$\pi$ phase shift upon reflection in quantum wells
Is there a similar phenomenon to the $\pi$ phase shift experienced by light upon reflection from a medium of lower to higher refracted index for particles in different potentials?
For instance, does a ...

Are reflection and transmission coefficients in 1D problem are independent of the direction in which we choose as incident?
I was watching a lecture series of Quantum mechanics of Professor V. Balakrishnan,
There was a problem session,
“For an arbitrary potential barrier (any potential function of position and it need not ...

Free particle encountering an infinite potential barrier
I understand that a wave function cannot penetrate through a barrier that has infinite potential. However when the wave function reflects off from the barrier what does this look like? If we're in a ...

Reflections from both edges of a finite well
In section 11.3.1 in Richard Robinnett's Quantum Mechanics book, it says that in the case of transmission resonance ($T=1$), there's complete destructive interference between waves reflected from the ...

Why do we suppose that reflected quantum state has the same energy that initial state?
I just read in my lecture notes that the teacher assumed the wave vector $k_+$ of reflected (from potential) state the same (but inverted) as wave vector of initial psi function (that goes to the ...

Mirror symmetry of spin-1/2 wavefunction: Definition of the reflection operator
I would expect from a reflection operator $\hat{M}$ to leave a wavefunction unchanged if two times applied, thus $\hat{M}^2=1$. However, for a spin-1/2 particle this is not the case when following the ...

Confusion about the reflection coefficient when a particle going through a potential
Suppose we have a potential$$ V(x) =
\begin{cases}
0, & \text{if $ x \le 0$} \\
V_0 & \text{if $ x \gt 0$ }
\end{cases}$$
The reflection coefficient for the case $E \lt V_0$ is $1$, which ...

Reflection in Finite Square Wells
For a Finite Square Well where we have a wavefunction $\psi(x)$ which is an energy eigenfunction with eigenvalue $E = 2V_0$ in the following potential:
$V(x) =
\begin{array}{ll}
6V_0 &...
