Open-quantum-system theory of non-Markovian electron-phonon dynamics
Gabriele Riva, Jacopo Simoni, Yuan Ping
We present a non-Markovian open-quantum-system formalism for nonequilibrium electron-phonon dynamics: a closed set of five coupled equations of motion, derived directly from the de…

Phonon-Assisted Radiative Lifetimes and Exciton Dynamics from First Principles
Chunhao Guo, Gabriele Riva, Jacopo Simoni +2
Exciton-phonon interactions play a fundamental role in phonon-assisted radiative recombination and exciton dynamics in solids. In this work, we present a first-principles framework…

First-principles open quantum dynamics for solids based on density-matrix formalism
Jacopo Simoni, Gabriele Riva, Yuan Ping
The theoretical description of materials' properties driven out of equilibrium has important consequences in various fields such as semiconductor spintronics, nonlinear optics, con…
