Coupled oscillators, entangled oscillators, and Lorentz-covariant harmonic oscillators
Coupled oscillators, entangled oscillators, and Lorentz-covariant harmonic oscillators
Other than scattering problems where perturbation theory is applicable, there are basically two ways to solve problems in physics. One is to reduce the problem to harmonic oscillators, and the other is to formulate the problem in terms of two-by-two matrices. If two oscillators are coupled, the problem combines both …
