A perspective on Lindblad's Non-Equilibrium Entropy
Erik Aurell, Ryoichi Kawai
Göran Lindblad in 1983 published a monograph on non-equilibrium thermodynamics. We here summarize the contents of this book, and provide a perspective on its relation to later deve…
Heat pump driven entirely by quantum correlation
Tharon Holdsworth, Ryoichi Kawai
The second law of thermodynamics prohibits spontaneous heat from a cold to a hot body. However, it has been theoretically and experimentally shown that energy can flow from a cold…
A qubit strongly interacting with a bosonic environment: Geometry of thermal states
Patrick Lee Orman, Ryoichi Kawai
A standard theory of thermodynamics states that a quantum system in contact with a thermal environment relaxes to the equilibrium state known as the Gibbs state wherein decoherence…
Entropy production of a small quantum system under strong coupling with an environment: A computational experiment
Ketan Goyal, Xian He, Ryoichi Kawai
Many theoretical expressions of dissipation along non-equilibrium processes have been proposed. However, they have not been fully verified by experiments. Especially for systems st…
Steady state thermodynamics of two qubits strongly coupled to bosonic environments
Ketan Goyal, Ryoichi Kawai
When a quantum system is placed in thermal environments, we often assume that the system relaxes to the Gibbs state in which decoherence takes place in the system energy eigenbasis…
Optical levitation of microdroplet containing a single quantum dot
Yosuke Minowa, Ryoichi Kawai, Masaaki Ashida
We demonstrate the optical levitation or trapping in helium gas of a single quantum dot (QD) within a liquid droplet. Bright single photon emission from the levitated QD in the dro…
