$\pi$ 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 ...

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 ...

Question about hard well potential in quantum mechanics
How we can treat the potential that is infinity on one side and zero for other side
$$V(x)=\begin{cases}0~~~~~~~~~x>0\\ +\infty~~~~~ x<0 \end{cases}$$
I think we must apply the one boundary ...

Definition of transmission and reflection coefficients for a particle
Quick intro:
A 1D quantum particle is subject to the potential
$$
V(x) = \begin{cases}
0 \;\;\;\;\; x\leq 0\\
V_0 \;\;\; x > 0
\end{cases}
$$
I am trying to understand the definition of ...

What's the intuition for the reflection of a quantum particle at a potential step equal to the particle's energy?
While doing the problem of potential step, I saw that if the energy of the particle is equal to the potential energy of the step, then the wave function is a constant, or to say the probability ...

Is it possible the opposite of tunneling?
In tunneling we have particles of energies $E<V$ going through barriers of potential $V$. Can we get particles of energies $E>V$ get reflected by these barriers of smaller potentials?

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 ...
