Time evolution of Renyi entropy under the Lindblad equation
Sumiyoshi Abe
In recent years, the Renyi entropy has repeatedly been discussed for characterization of quantum critical states and entanglement. Here, time evolution of the Renyi entropy is stud…

Weak invariants of time-dependent quantum dissipative systems
Sumiyoshi Abe
The concept of weak invariant is introduced. Then, the weak invariants associated with time-dependent quantum dissipative systems are discussed in the context of master equations o…

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…
