s-wave, p-wave or d-wave collisions in scattering theory
2014年1月22日 · S wave is the zero angular momentum quantum number , l=0, and will correspond to a classical head on ...
What is a phase of a wave and a phase difference?
2018年8月12日 · If you make an arbitrary choice and say your wave "starts" when it's height is 0, then if you start a second wave a short time later it will be out of phase with the first wave. If …
What is the relation between electromagnetic wave and photon?
2014年12月18日 · electromagnetic wave is a chain reaction of electric and magnetic fields creating each other so the chain of wave moves forward. It's clear this doesn't have to be true. …
What are $s$-wave collisions? - Physics Stack Exchange
2022年10月27日 · Atom cooling involves photons interacting with atoms. These interactions are sometimes called scattering. The system undergoing the scattering has an angular momentum …
How is the Schroedinger equation a wave equation?
$|\partial_t \dot{\psi}| \ll \omega |\dot{\psi}|$ means that the envelope function's time derivative $\dot{\psi}$ is changing much more slowly than the plane wave is oscillating (i.e. many plane …
Phase shifts in scattering theory - Physics Stack Exchange
Its used in partial wave analysis, a common orthogonal expansion . Any function can be decomposed into infinitely many partial waves, the different partial waves correspond to …
Wave packets v.s. wave trains - Physics Stack Exchange
A wave train simply means a series of more or less equally spaced wave crests. A wave packet generally means a collection of waves with neighboring wavenumbers, which interfere to …
Why can't transverse waves travel through a liquid?
2015年2月11日 · Note that the orientation relative to gravity is irrelevant (so horizontal and vertical don't really mean anything unless you're talking about gravity waves) In longitudinal waves the …
Born Interpretation of Wave Function - Physics Stack Exchange
Now quantum mechanics is wave mechanics, mathematics is similar but interpretation varies. But particles and waves are two exclusive phenomenon, to join them De broglie's hypothesis was …
condensed matter - What is a $p_x - Physics Stack Exchange
I would like to particularly address this nice question relating the Hamiltonian formulation of this superconducting state (via Bogoliubov-de Gennes (BdG) equation) to the low energy quantum …
