On the open Dicke-type model generated by an infinite-component vector spin
Ryota Kyokawa, Hajime Moriya, Hiroshi Tamura
We consider an open Dicke model comprising a single infinite-component vector spin and a single-mode harmonic oscillator which are connected by Jaynes--Cummings-type interaction be…

Markov property and strong additivity of von Neumann entropy for graded quantum systems
Hajime Moriya
It is easy to verify the equivalence of the quantum Markov property and the strong additivity of entropy for graded quantum systems as well. However, the structure of Markov states…

On separable states for composite systems of distinguishable fermions
Hajime Moriya
We study characterization of separable (classically correlated) states for composite systems of distinguishable fermions that are represented as CAR algebras.
