Approaching Carnot Efficiency at Finite Power in an Experimentally Feasible Quantum Heat Engine
Shogo Toma, Atsushi Noguchi, Ken Funo +1
Whether a heat engine can approach Carnot efficiency while maintaining finite power is a fundamental question in finite-time thermodynamics. For classical Markovian heat engines wi…
Hierarchy of entropy production and thermodynamic trade-off relations in non-Markovian systems
Ken Funo, Tan Van Vu, Keiji Saito
Non-Markovian dynamics arise when a system is coupled to a bath with finite correlation time, producing memory effects that can modify finite-time thermodynamic behavior. We study…
Improvement of Speed Limits: Quantum Effect on the Speed in Open Quantum Systems
Kotaro Sekiguchi, Satoshi Nakajima, Ken Funo +1
In the context of quantum speed limits, it has been shown that the minimum time required to cause a desired state conversion via the open quantum dynamics can be estimated using th…
Symmetry induced enhancement in finite-time thermodynamic trade-off relations
Ken Funo, Hiroyasu Tajima
Symmetry imposes constraints on open quantum systems, affecting the dissipative properties in nonequilibrium processes. Superradiance is a typical example in which the decay rate o…
