Transport properties of electron-phonon coupled systems
PI: Prof. Fabian Heidrich-Meisner
This project studies the transport properties and charge-carrier relaxation dynamics in electron-phonon coupled systems. We will employ computational many-body methods to address these main goals: non-equilibrium transport in heterostructures with polaronic charge carriers, the melting of charge-density wave states after optical excitations, the computation of the optical conductivity in electron-phonons systems and the development of efficient numerical finite-temperature methods.

| In our recent study Stolpp et al. Phys. Rev. B 101, 035134 (2020), we investigate the decay of charge density waves states in the one-dimensional Holstein modelin various parameter regimes (see part (a) of the figure for a sketch). The lower panel shows the phase diagram of the model at half filling (obtained in other studies, see references in our publication). |
