Quantum dynamics and thermodynamics in nanosystems with strong electronic-vibrational coupling under external driving — •Jakob Bätge1, Wenjie Dou2, Amikam Levy3, and Michael Thoss1 — 1Institute of Physics, University of Freiburg, Freiburg, Germany — 2School of Science, Westlake University, Hangzhou, China — 3Department of Chemistry, Bar-Ilan University, Ramat-Gan, Israel
The development and optimization of quantum devices increase the interest in dynamics and thermodynamics of systems on the scale of single atoms and molecules. In this contribution, we investigate the nonequilibrium quantum dynamics of a time-dependent driven nanosystem with interacting electronic and vibrational degrees of freedom utilizing the numerically exact hierarchical equations of motion approach for multiple fermionic and bosonic environments [1]. We analyze the role of vibrations in the electronic friction induced by electronic-vibrational coupling and identify the adiabatic and nonadiabatic contributions to thermodynamic quantities[2].
