Generalized Adiabatic Impulse Approximation
Takayuki Suzuki, Hiromichi Nakazato
Non-adiabatic transitions in multilevel systems appear in various fields of physics, but it is not easy to analyze their dynamics in general. In this paper, we propose to extend th…

Vacuum decay and fermion total reflection by the Klein step
H. Nakazato, M. Ochiai
The so-called Klein tunneling is re-examined within the framework of quantum field theory, but from a different point of view on the asymptotic states. We treat it as a one-dimensi…

Analytic approach to dynamics of the resonant and off-resonant Jaynes-Cummings systems with cavity losses
Soshun Ozaki, Hiromichi Nakazato
A new analytic approach to investigate the zero-temperature time evolution of the Jaynes-Cummings system with cavity losses is developed. With the realistic coupling between the ca…
