zeeman-type spin splitting in non-magnetic three-dimensional compounds: materials prediction and electrical control

Answers

Answer 1

Zeeman-type spin splitting in non-magnetic three-dimensional compounds: materials prediction and electrical control.

The Zeeman Effect:

The discussion of the atomic energy levels, their transitions, and the related spectral lines has implicitly assumed that the atom is not affected by magnetic fields. The atomic energy levels are split into a greater number of levels and the spectral lines are likewise split when magnetic fields are present. The Zeeman Effect is referred to as this splitting.

The non-magnetic Zeeman effect has only been predicted and observed in two-dimensional molecules, despite its potential for device application. We show that Zeeman-type spin splitting may also occur in non-centrosymmetric three-dimensional compounds and that this splitting can be controlled by altering the direction in which these compounds' slabs expand. We identify the necessary elements for this effect: A general k-point must have the following characteristics:

(i) non-centrosymmetric, including polar and non-polar point groups;

(ii) valence band maximum or conduction band minimum;

(iii) non-time-reversal-invariant momentum; and

(iv) zero magnetic moment.

We do a material screening to systematically look for these systems in the aflow-ICSD database using these criteria as filters. 20 material candidates with the Zeeman-type effect are discovered.

We also discovered that an external electric field, which in turn can cause a metal-insulator transition, can influence spin-splitting in restricted systems. We propose a spin-filtering device based on the Zeeman-type phenomenon in three-dimensional compounds.

Two blocks on a surface of negligible friction are attached together by a spring, as shown in the figure above. The mass of block 1 is MM, and the mass of block 2 is 2M. Block 1 is initially moving toward block 2, which is at rest. The spring compresses and decompresses in a repeated motion as the two blocks slide to the right. Which of the following statements best describes the speed of the center of mass of the two-block system?

Answers

In the absence of an external force, the total linear momentum of the system maintains conservation, indicating that the speed of the system's center of mass is constant.

This is because the spring force between the masses acts as an internal force between the two masses.

The product of an object's mass, m, and velocity, v, is known as linear momentum, and it is a vector quantity. In order to express it and refer to momentum informally, the letter "p" is utilized. You should be aware that a body's momentum always points in the same direction as its velocity vector. Because it is a conserved quantity, the overall momentum of a system is always constant. Linear momentum is measured in kg/s.

The total linear momentum prior to an object's interaction and the total linear momentum following that interaction is identical. Any system of objects that is subject to no net external force has a constant total linear momentum.

Answers

The free-fall acceleration on the planet 2 will be 6 m/sec².

Acceleration is the rate of change of velocity with respect to time.

Also it defines the maximum capacity of a vehicle to attain its speed.Its SI unit is m/sec².

As we know that acceleration due to gravity can be expressed as

g = MG / R²

M = mass of the planet

G = Gravitational constant

R = radius of the planet

For planet 1

Mass = M1 = M

Radius = R1 = R

Acceleration due to gravity = g1 = 12 m/sec²

G = g1R1²/M1

For planet 2

Mass = M2 = 2M

Radius = R2 = 2R

Acceleration due to gravity = g2 = ?

G = g2R2²/M2

Since 'G' is constant, therefore on equating both the equations, g2 can be calculated

g2 = (g1R1²/M1) * (M2/R2²)

a 1.8-cmcm-tall object is 22 cmcm to the left of a lens with a focal length of 11 cmcm . a second lens with a focal length of -5 cmcm is 37 cmcm to the right of the first lens.

Answers

A lens with an 11 cm focal length is 22 cm to the left of a 1.8 cm tall object. The image's height has decreased by 0.25 pixels when a second lens with a focal length of -5cm is placed 37cm to the right of the first lens.

Let's determine the distance at which the image is formed from the first lens since the image of the first lens serves as a virtual object for the second lens. Use the lens manufacturer's formula:

1/o + 1/i = 1/f, where I am the image distance and o is the object distance,

1/i = 1/f - 1/o = 1/(11cm) - 1/(22cm) = 0.045 1/cm, so

i = 22cm

the virtual object for the second lens is left at a distance of 37 cm - 22 cm, or 15 cm, from the second lens. Utilize the lens manufacturer's formula once more:

1/i = 1/f - 1/o (This time, the object distance is the separation between the second lens and the virtual object.)

1/i = 1/(-5cm) - 1/(15cm) = -0.26 1/cm, so

i = -15/4cm away from the second lens.

The sum of the two magnifications from the two lenses is the total magnification: m = m1m2, where m = -i/o, so

m = (-22 cm/22 cm)( 15/4cm/15cm) = -0.25, Consequently, the image's height is 0.25 pixels shorter than it was before.

It is the inverse of the system's optical power that determines how strongly an optical system diverges or converges light: the focal length. The convergence or divergence of light is indicated by a positive focal length, whilst the opposite is true for a negative focal length.

Since two point sources S₁ and S₂, Which are in phase and emit identical sound waves of wavelength 2.0 m: The length L₁ = 21 m. A listener stands at point P: Assume the amplitude of individual sound reaching at point P does not change, to find L₂, we need to know the path difference for destructive interference.

What is path difference for destructive interference?

The path difference for destructive interference is given by ΔL = (n + 1)λ/2

where

ΔL = path difference = L₂ - L₁, λ = wavelength and n is an integer.

Since we require the least intensity, we have the minimum interference. So, n = 0.

So, ΔL = (n + 1)λ/2

ΔL = (0 + 1)λ/2

L₂ - L₁ = λ/2

So, making L₂ subject of the formula, we have

L₂ = L₁ + λ/2

Given that

L₁ = 21 mλ = 2.0 m

Substituting the values of the variables into the equation, we have that

L₂ = L₁ + λ/2

The block is propelled along a horizontal surface as the spring is let go. Friction and the spring's bulk can be disregarded. Between two blocks with masses of 1 kg and 2 kg that are lying on a smooth horizontal surface is a compressed elastic spring. The block is freed from rest once the spring has been compressed by 2.0 cm.

If two metal blocks of different masses slide freely down the same frictionless incline,
which one of the following is true?
A) They have equal accelerations
B) They have unequal accelerations, but the forces acting on them are equal.
C) The more massive block reaches the bottom first.
D) The less massive block reaches the bottom first.
E) None of these is correct.

Answers

If two metal blocks of different masses slide freely down the same frictionless incline, option a is correct.

Objects accelerate due to imbalanced forces. However, not every item accelerates at the same rate in the presence of the same imbalanced force. As a result, the speed and net force in the direction perpendicular to the plane must both be zero. Since the plane is assumed to be "frictionless," no force is applied to the block that is perpendicular to the surface by the plane. The acceleration is determined by multiplying the acceleration of gravity by the sine of the angle for a frictionless incline of angle degrees. The force of gravity is not parallel to the surface when there is an inclination. The normal force diminishes as the angle of the incline increases, which reduces the frictional force. You can increase the inclination until the thing barely starts to slip.

the rod has a diameter of 40 mm. if it is subjected to the force system shown, determine the stress components that act at point a, and show the results on a volume element located at this point

Answers

In this case, we are given that the rod is subjected to the force system shown in the figure. There is a vertical force F acting on the rod at point A, as well as a horizontal force P. The rod is also subjected to a moment M about the z-axis.

To determine the stress components that act at point A, we need to consider the forces that are acting on a small volume element located at this point.

The stress on a volume element is defined as the force acting on the element per unit area. The stress components at a point can be represented by a stress tensor, which is a 3x3 matrix with nine elements. The diagonal elements of the stress tensor represent the normal stress components, while the off-diagonal elements represent the shear stress components.

To determine the stress components at point A, we need to consider how these forces are distributed over the surface of the volume element. The normal stress components can be found by considering the forces acting perpendicular to the surface of the element. The shear stress components can be found by considering the forces acting tangent to the surface of the element.

For example, the normal stress component in the x-direction at point A can be found by considering the force F acting perpendicular to the surface of the element in the y-direction. The normal stress component in the y-direction at point A can be found by considering the force P acting perpendicular to the surface of the element in the x-direction. The shear stress component in the XY-plane at point A can be found by considering the moment M acting tangent to the surface of the element.

To determine the specific values of the stress components, we would need to know the dimensions of the volume element, as well as the magnitudes of the forces and moments acting on the rod. With this information, we can use the equations of statics to solve for the stress components at point A.

When the filament breaks in one lamp in a parallel circuit, lamps in other branches of the circuit normally continue glowing as brightly.

What is Parallel Circuit Connection ?

There are precisely two sets of electrically common points formed by the connections of all parts across one another. A path for electrical current created by one of the load components is referred to as a "branch" in a parallel circuit (such as a resistor).

The fact that it is all connected in parallel sequences, hence the name, is a crucial component of the "parallel" circuit. The "rungs" on either side of this sort of circuit must be descended for a current to pass through each component.

Aparallel circuit's characteristics :

The identical two places are joined by each gadget.The parallel branches divide the circuit's overall current.The overall current in the circuit is equal to the sum of the currents in the parallel branches.As the number of branches increases, the circuit's total resistance lowers.

There are two forces on the 2.00kg box in the overhead view of Fig., but only one is shown. For F 1​ =20.0N,a=12.0m/s 2, and θ=30.0 o, find the second force (a) in unit-vector notation and as (b) a magnitude and (c) an angle relative to the positive direction of the x axis.

Answers

The unit vector of the second force is [tex]\frac{-32i-12.3^1/2}{38.16}[/tex], and its magnitude is 38.16N and the angle is 147 with a positive x-axis.

According to the question

a= 12m/s^2

m=2kg

F=24N

Fx= Fsin30 = 24.1/2=12

   = 12(-i)

Fy= Fcos30 = 12√3N

   = 12√3(-j)

F=-12i-12√3j

F1=20j,        F2=F-F1= -32i-12√3j

                  F2=38.16N

(a) Unit vector = [tex]\frac{F2}{|F2|}[/tex] =[tex]\frac{-32i-12.3^1/2}{38.16}[/tex]

(b)Magnitude= 38.16N

(c) Angle= [tex]tan^{-1}[/tex][tex]\frac{y}{x}[/tex] = 33 means 33 with - x axis. so with the + x-axis it will be 180-33= 147

Therefore

The unit vector of the second force is [tex]\frac{-32i-12.3^1/2}{38.16}[/tex] and its magnitude is 38.16N and the angle is 147 with a positive x-axis

A 20-cm-diameter circular cover is placed over a 10-cm-diameter hole that leads into an evacuated chamber. The pressure in the chamber is 16kPa. How much force is required to pull the cover off?

Answers

A 10-cm-wide opening leading into an evacuated chamber is covered with a circular 20-cm-diameter lid. It exerts a 638 N force.

What is the force is required to pull the cover off ?

20 kPa is the chamber's pressure. The formula for calculating the required force is Force = difference in pressure x area of plate.

[tex]$F=\left(P_2-P_1\right) \times A \ldots$$F=\left(P_2-P_1\right) \times \pi r^2$$P_1=20000 \mathrm{~Pa}$$P_2=101325 \mathrm{~Pa}$$r=0.05 \mathrm{~m}$[/tex]

Now adjust equation (1) to reflect the new values, and calculate

[tex]$F=(101325-20000) \times 3.14 \times(0.05)^2=638 \mathrm{~N}$[/tex]

638 N of force is required.

The numbers from each of these observations and calculations should be entered into the primary equation, F = pA, where F is the piston force (F) in newtons (N), p is the gauge pressure, and A is the complete bore area.

An object's speed, direction of motion, or shape can all be altered by applying a force to it. A measurement of the force operating on a region is called pressure. The formula pressure = force / area can be used to calculate pressure. A force will therefore exert higher pressure while working across a smaller region.
