Two-level adiabatic transition probability for small avoided crossings generated by tangential intersections

Kenta Higuchi, Takuya Watanabe

In this paper, the asymptotic behaviors of the transition probability for two-level avoided crossings are studied under the limit where two parameters (adiabatic parameter and ener…

Spectral analysis of three-state quantum walks with general coin matrices

Chusei Kiumi, Jirô Akahori, Takuya Watanabe +1

Mathematical analysis of the spectral properties of the time evolution operator in quantum walks is essential for understanding key dynamical behaviors such as localization and lon…

Landau-Zener Formula in a "Non-Adiabatic" regime for avoided crossings

Takuya Watanabe, Maher Zerzeri

We study a two-level transition probability for a finite number of avoided crossings with a small interaction. Landau-Zener formula, which gives the transition probability for one…

Widths of resonances above an energy-level crossing

Setsuro Fujiié, André Martinez, Takuya Watanabe

We study the existence and location of the resonances of a semiclassical system of coupled Schrödinger operators, in the case where the two electronic levels cross at s…

Molecular predissociation resonances near an energy-level crossing II: Vector field interaction

Setsuro Fujiie, André Martinez, Takuya Watanabe

We study the resonances of a two-by-two semiclassical system of one dimensional Schrödinger operators, near an energy where the two potentials intersect transversally, one of them…
