(Charla) Thermodynamics and role of coherences in quantum-dot-based nanomachines

Conferencia; Transport at the Nanoscale; 2020

In this talk, I will briefly review the dynamical and thermodynamical aspects of different forms of quantum motors and quantum pumps. I will then focus on two key topics: (1) The steady-state regime of quantum motors and pumps, paying particular attention to the role of higher order terms in the nonadiabatic expansion of the current-induced forces. (2) The thermodynamical properties of such systems, emphasizing systematic ways of studying the relationship between different energy fluxes (charge and heat currents and mechanical power) passing through the system. Finally, I will illustrate the above-discussed topics in a double quantum dot within the Coulomb-blockade regime and capacitively coupled to a mechanical rotor.
