Nonadiabatic Transitions for a Decaying Two-Level-System: Geometrical and Dynamical Contributions
R. Schilling, Mark Vogelsberger, D. A. Garanin
We study the Landau-Zener Problem for a decaying two-level-system described by a non-hermitean Hamiltonian, depending analytically on time. Use of a super-adiabatic basis allows to…

Saddle index properties, singular topology, and its relation to thermodynamical singularities for a phi^4 mean field model
D. A. Garanin, R. Schilling, A. Scala
We investigate the potential energy surface of a phi^4 model with infinite range interactions. All stationary points can be uniquely characterized by three real numbers $α_+, alpha…
