Action principle and weak invariants
Sumiyoshi Abe, Congjie Ou
A weak invariant associated with a master equation is characterized in such a way that its spectrum is not constant in time but its expectation value is conserved under time evolut…
Improvement of superconducting properties by high mixing entropy at blocking layers in BiS2-based superconductor REO0.5F0.5BiS2
Ryota Sogabe, Yosuke Goto, Tomohiro Abe +5
To investigate the interlayer interaction in the recently synthesized high-entropy-alloy-type (HEA-type) REO0.5F0.5BiS2 superconductors (RE: rare earth), we have systematically syn…
Comment on "Route from discreteness to the continuum for the Tsallis q-entropy"
Congjie Ou, Sumiyoshi Abe
Several years ago, it has been discussed that non-logarithmic entropies such as the Tsallis q-entropy cannot be applied to systems with continuous variables. Now, in their recent p…
Maximum Power Output of Quantum Heat Engine with Energy Bath
Shengnan Liu, Congjie Ou
The difference between quantum isoenergetic process and quantum isothermal process comes from the violation of the law of equipartition of energy in the quantum regime. To reveal a…
Lindbladian operators, von Neumann entropy and energy conservation in time-dependent quantum open systems
Congjie Ou, Ralph V. Chamberlin, Sumiyoshi Abe
The Lindblad equation is widely employed in studies of Markovian quantum open systems. Here, firstly, a simple result is presented on the time evolution of the non Neumann entropy…
Exotic properties and optimal control of quantum heat engine
Congjie Ou, Sumiyoshi Abe
A quantum heat engine of a specific type is studied. This engine contains a single particle confined in the infinite square well potential with variable width and consists of three…
