Semiclassical shape resonances for magnetic Stark Hamiltonians
Kentaro Kameoka, Naoya Yoshida
We study shape resonances of two-dimensional magnetic Stark Hamiltonians in the semiclassical limit. The magnetic field is assumed to be constant and the scalar potential is a pert…

Continuum limit of resonances for discrete Schrödinger operators
Kentaro Kameoka, Shu Nakamura
We consider complex resonances for discrete and continuous Schrödinger operators, and we show that the resonances of discrete models converge to resonances of continuous models in…

Many-body Stark resonances by the complex absorbing potential method
Kentaro Kameoka
The resonances of many-body Stark Hamiltonians are characterized by the complex absorbing potential method. Namely, the resonances are shown to be the limit points of complex discr…
