Coherent path integral

WebA recurrent theme in his research is the role played by coherent states, in particular, in connection with path integral formulations of quantization. Perhaps at a less lofty level, this concept has had at least two spectacular applications: as a powerful investigative tool in quantum optics and as a precursor to wavelets. WebIn the Hilbert space of a quantum particle the standard coherent-state resolution of unity is written in terms of a phase-space integration of the outer product . Because no pair of coherent states is orthogonal, one c…

WebOct 10, 2024 · Classical Mechanics of the Simple Harmonic Oscillator. To define the notation, let us briefly recap the dynamics of the classical oscillator: the constant energy is E = p2 2m + 1 2kx2. or p2 + (mωx)2 = 2mE, ω = √k / m. The classical motion is most simply described in phase space, a two-dimensional plot in the variables (mωx, p).
