Description
We present recent developments using the temperature dependent effective
potential technique (TDEP) to model strongly non-harmonic materials. The
method employs model Hamiltonians that explicitly depend on temperature.
I will present applications pertaining to thermal conductivity,
inelastic neutron spectra and phase stabilities. In addition, we
investigate non-linear electron-phonon coupling and its influence on
phonon spectra, and recent additions to that deal with nuclear quantum
effects and efficient stochastic sampling.
