4-6. Calculate the values of = {E2)-(E)2 for a particle in a box in the state described by 6301 12
(15) 4. The state of the particle-in-a box located between 0<x<a is described by the following normalized wavefunction at t=0: Y(x,t=0) =(1/2) A Sin (fx/a)-(1/12) A Sin(3 rex/a) + (1/2) A Sin(5tx/a) (10) a) If the energy of the system is measured at t=0, what energies will be observed What is the probability (in percent) of observing an energy E> 9h-/8ma?? on
P7D.4 Calculate the expectation values of p, and p? for a particle in the state with n- 2 in a one-dimensional square-well potential
Calculate : i) degeneracy of the ground state of a particle in a linear (1-dimensional) box ii) Degeneracy of the ground state of a particle in a cubic (3-dimensional) box The answer is both same number of degeneracy. WHY? please showing calculation and explain
this is statistical mechanics
4. Calculate the probability that at 300 K a given particle in a 2D square box with a length of 1 cm is found in a) the quantum state (nx, ny) (3,1). b) the energy level e.

2.2 Two-level system A particle in the box is described by the following wavefunction 1 1 V(x, t) + V2 V2 = Um(x)e -i(Em/h) In other words, this state is a superposition of two modes: n-th, and m-th. A superposition that involves only two modes (not necessarily particle in the box modes, but any two modes) is called a "two-level system”. A more modern name for such a superposition is a "qubit”. a) Come up with an expression for the...

uion or the for a particle in a box in a state described in the previous problem. Plot your result through one cycle. blem, we shall develop the consequence of measuring the position of a particle 4-42. In this box. If we find that the particle is located between a/2-/2 and a/2+/2, then its wave function may be ideally represented by a/2 - /2 <x <a/2+/2 x > a/2+/2 Plot ?(x) and show that...

09 Estimate the ground state energy and wavefunction for a particle in a box using the variational method with the following trial wavefunction, where N is the normalization constant and ß is a variational parameter that should be minimized. 14) = N exp(-Bx2) (7.6) 1. Is this a good trial wavefunction for this approximation (justify your answer)? 2. Why is this not a good wavefunction? 3. Can you solve this problem both analytically and numerically? Pay careful attention to limits...
