Charge and spin correlations of a Peierls insulator after a quench | | Martin Hohenadler
; | | Date: |
22 Mar 2013 | | Abstract: | Electron-phonon coupling plays a central role for time-dependent phenomena in
condensed matter, for example in photo-excitation experiments. We use the
continuous-time quantum Monte Carlo method to study the real-time evolution of
charge and spin correlation functions of a Peierls insulator after a quench to
a noninteracting Hamiltonian. This approach gives exact results, and fully
takes into account quantum phonon effects without relying on a Hilbert space
truncation. It is also free from a dynamical sign problem. Since thermalization
is absent for a quench to an integrable model, we observe dephasing over a time
scale set by the electronic hopping integral. Our exact results provide a
benchmark for more realistic calculations, and may be directly applicable to
experiments with cold atoms or trapped ions. | | Source: | arXiv, 1303.5682 | | Services: | Forum | Review | PDF | Favorites | |
