Entropy Dynamics of Phonon Quantum States Generated by Optical Excitation of a Two-Level System
In quantum physics, two prototypical model systems stand out due to their wide range of applications. These are the two-level system (TLS) and the harmonic oscillator. The former is often an ideal model for confined charge or spin systems and the latter for lattice vibrations, i.e., phonons. Here, w...
