Dynamics of two interacting dipolar two-level systems in a multi-mode electromagnetic cavity: sudden death and revival of the entanglement within the Born-Markov approximation
Loann Quien, Naomichi Hatano
The paper analyzes the dynamics of two interacting dipolar two‑level systems (qubits) inside a multi‑mode electromagnetic cavity using the Born‑Markov approximation, deriving exact…
Markovianity and non-Markovianity of Particle Bath with Dirac Dispersion Relation
Takano Taira, Naomichi Hatano, Akinori Nishino
The dynamics of a two-level system coupled to a particle bath with the Dirac dispersion relation is studied. We analytically show that closing the Dirac gap results in a transition…
Fractional power-law decay in the spontaneous emission of a two-level system
Hiroki Nakabayashi, Hayato Kinkawa, Takano Taira +1
It has been shown for various systems that the decay rate of an unstable quantum system deviates from exponential behavior in short- and long-time regimes associated with memory ef…
Non-equilibrium Dynamics of Three-Level Absorption Refrigerator at Third-Order Liouvillian Exceptional Points
Jingyi Gao, Naomichi Hatano
We analyze the influence of Liouvillian exceptional points (LEPs) in the three-level quantum absorption refrigerator, putting emphasis on the non-equilibrium process before the con…
