Small phase theorem
WebMar 16, 2024 · The initial configuration fills a region of phase space that includes a particle at rest at the origin (lower left corner of the shaded shape. This initial region includes a small initial displacement (up to approximately Δx) as well as a small initial momentum (up to approximately Δp). WebAdiabatic theorem and Berry phase. As far as I can check, the adiabatic theorem in quantum mechanics can be proven exactly when there is no crossing between (pseudo-)time-evolved energy levels. To be a little bit more explicit, one describes a system using the Hamiltonian H ( s) verifying H ( s = 0) = H 0 and H ( s = 1) = H 1, with s = ( t 1 ...
