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…

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…
