We analyze the time-resolved energy transport and the entropy production in ac-driven quantum coherent electron systems coupled to multiple reservoirs at finite temperature. At slow driving, we formulate the first and second laws of thermodynamics valid at each instant of time. We identify heat fluxes flowing through the different pieces of the device and emphasize the importance of the energy stored in the contact and central regions for the second law of thermodynamics to be instantaneously…

Periodic Energy Transport and Entropy Production in Quantum Electronics
From a thermodynamical perspective recent investigations on nonstationary heat and work generated in quantum systems, emphasizing open questions and unsolved issues are discussed.
Charge and energy transfer in ac-driven Coulomb-coupled double quantum dots
We study the dynamics of charge and energy currents in a Coulomb-coupled double quantum dot system, when only one of the two dots is adiabatically driven by a time-periodic gate that modulates
Simulating time-dependent thermoelectric transport in quantum systems
We put forward a gauge-invariant theoretical framework for studying time-resolved thermoelectric transport in an arbitrary multiterminal electronic quantum system described by a noninteracting
Quantum thermodynamics of the resonant-level model with driven system-bath coupling
We study nonequilibrium thermodynamics in a fermionic resonant level model with arbitrary coupling strength to a fermionic bath, taking the wide-band limit. In contrast to previous theories, we
Work exchange, geometric magnetization, and fluctuation-dissipation relations in a quantum dot under adiabatic magnetoelectric driving
We study the adiabatic dynamics of the charge, spin and energy of a quantum dot with a Coulomb interaction under two-parameter driving, associated to time-dependent gate voltage and magnetic field.
Transport and thermodynamics in quantum junctions: A scattering approach.
We present a scattering approach for the study of the transport and thermodynamics of quantum systems strongly coupled to their thermal environment(s). This formalism recovers the standard
Anomalous Joule law in the adiabatic dynamics of a normal-superconductor quantum dot
We formulate a general theory to study the time-dependent charge and energy transport of an adiabatically driven quantum dot in contact to normal and superconducting reservoirs at T = 0. This setup
Thermodynamics and Steady State of Quantum Motors and Pumps Far from Equilibrium
A general order-by-order scheme based on energy conservation is derived to rationalize how every order of the expansion of one form of energy flux is connected with the others of the system when beyond-first-order expansions are required.
Heat transport in a two-level system driven by a time-dependent temperature
The field of thermotronics aims to develop thermal circuits that operate with temperature biases and heat currents just as how electronic circuits are based on voltages and electric currents. Here,
