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…
