Analytical Approximations to the Dynamics of Nonlinear Level Crossing Models
Chon-Fai Kam, Yang Chen
We study the dynamics of a nonlinear two-level crossing model with a cubic modification of the linear Landau-Zener diabatic energies. The solutions are expressed in terms of the bi…

Analytical Results for the Dynamics of Parabolic Level-Crossing Model
Chon-Fai Kam, Yang Chen
We study the dynamics of a two-level crossing model with a parabolic separation of the diabatic energies. The solutions are expressed in terms of the tri-confluent Heun equations -…
