WebJun 10, 2024 · p is not a self-adjoint operator in case of the particle in a box problem. Hence your argument breaks down. However, p^2 remains well defined. This is treated in most texts on functional analysis. My preferred reference is Akhieser, Glazman, Theory of Linear Operators in Hilbert Space (Dover Books on Mathematics) WebThis is the same as the relation E = p^2/2m between energy and momentum for a free particle, if one adopts the correspondence E = hbar w and p = hbar k.

We want to set up a variational calculation to estimate the ground state energy. When the anisotropy is signi cant (C˛1 or C˝1), we do not expect the ground state to be even approximately rotationally invariant. Webso it is to quantum mechanics what Newton's first law is to particle mechanics. For a wave function of the form Aexp(-iwt)exp(ikx), Schrodinger's equation implies the dispersion relation hbar w = (hbar k)^2/2m.

This relationship comes directly from the definitions of momentum (p=mv) and kinetic energy (T=½mv 2). The derivation of this formula is extremely simple.

WebUsing operators, we can verify the time-dependent Schrodinger equation: p = - i ℏ ∂ /∂x p 2 = - ℏ 2 ∂ 2 /∂x 2 KE = p 2 /2m = - (ℏ 2 /2m) ∂ 2 /∂x 2 If we use the conservation of energy, that is KE + PE = E, and take the simplest case where the particle is free (PE = 0), we have KE = E, and then : - (ℏ 2 /2m) ∂ 2 /∂x 2 = i ℏ ∂ /∂t .
