Is the Hamiltonian generated by the external magnetic field in the neutron interferometry experiment like "potential energy"?
I believe that the Hamiltonian generated by the external magnetic field in the neutron interferometry experiment effectively leads to an increase in the neutron's potential energy.
Why is this ...

Does this experiment put an end to Copenhagen (and all epistolar) interpretations of QM?
The article from April 2022 in PhysRev Research is about the famous double slit experiment (Mach Zehnder variant) made with single neutrons and it proves that there is definitely something in both ...

Why is the plane wave $\tilde{A}e^{ikx}$ representing an isolated neutron not physically acceptable?
I consider a plane wave $Ae^{ikx-i\omega t}$ where $A \in \mathbb{C}$, $k = \frac{2\pi }{\lambda} \in \mathbb{R}$, $\omega = 2 \pi \nu = \frac{2\pi c}{\lambda} \in \mathbb{R}$ ($\lambda$ is the wave ...

Selection rules in neutron scattering
Why doesn't neutron scattering have selection rules?
According to Wikipedia, it seems that the value of the transition moment integral will be non-zero, but I guess another way of phrasing my question ...

Can a neutron act as a wave? Can the wave of light superpose with the wave of neutrons?
Can neutrons act as a wave? and can that wave superpose with wave of a photon? and what are, if any, the required conditions for that phenomenon to happen? Thirdly, if we pass light through completely ...

What does it mean that a neutron has a 'negative' magnetic moment?
Most questions about this ask why, or how, a neutron has a magnetic moment at all, or why it is negative....
But I am curious as to what it means, physically or experimentally, for a magnetic moment ...

How do neutron stars emit black body radiation?
If my understanding is correct, black body radiation is emitted by a substance due to the substances coupling with the electric field. The negatively charged electrons in atoms for example can couple ...

What colour would neutronium be? [duplicate]
Everything we learn about colour in relation to matter is based on "normal" matter that has electrons around it. Absorption and emission of electromagnetic radiation is explained in terms of ...

Doesn't the neutron's lack of an electric dipole moment conflict with the concept of baryons having a radius?
The proton radius puzzle appears to one of the more widely known unsolved problems in physics, but doesn't it point to a much deeper issue? Nearly all of a baryon's observed mass can be attributed to ...

If neutronium existed out there, are we capable of observing it? [duplicate]
I know that theoretically, neutronium cannot exist. However, no work was done until now even looking for neutronim around us. So my question is that, if neutronium actually existed with some minimum ...

Why protons are stable but Neutrons not?
just read something about standard model and find it very interesting, proton is made of there subatomic particle U,U,D and neutron have U,D,D .
electromagnetic force between U,U,D wants to rip apart ...

Quantum mechanics. Scattering from step potential barrier of magnetic field
I am having trouble to think how to solve the following problem:
The plane $x=0$ separates two parts of space: when $x>0$ there is homogeneous magnetic field, which induction vector $B_x=B_y=0$, ...

What is the escape velocity of a neutron particle (not neutron star)
I'm not sure if this question makes sense (if not maybe you can explain why)
But if the neutron has mass and have a size, then it should have a escape velocity in the "surface" right?
I know the ...

Why exactly is Neutronium-4 unstable and how to explain Marqués' experimental results?
Wikipedia states:
A tetraneutron is a hypothetical stable cluster of four neutrons. The existence of this cluster of particles is not supported by current models of nuclear forces. There is some ...
