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…
