Second-order adiabatic expansion of heat and charge currents within the nonequilibrium Green's function approach

Year: 2024

Type: article

Abstract: Nanoscale heat management and energy conversion require precise control of energy flow. Adiabatic expansions are key tools for studying time-dependent devices such as quantum motors and pumps, but their complexity has limited research to first-order approximations. This work develops a novel theoretical framework to calculate second-order energy, heat, and charge currents, enabling a deeper understanding of quantum thermodynamics and the study of unexplored phenomena, such as second-order monoparametric pumping.
