Probing anharmonic phonons in WS2 van der Waals crystal by Raman spectroscopy and machine learning
Summary: Understanding the optothermal physics of quantum materials will enable the efficient design of next-generation photonic and superconducting circuits.Anharmonic phonon dynamics is central to strongly interacting optothermal physics.This is because the pressure of a gas of anharmonic phonons is temperature dependent.Phonon-phonon and electro
