An all-optical event horizon in an optical analogue of a Laval nozzle
Moshe Elazar, Victor Fleurov, Shimshon Bar-Ad
Exploiting the fact that light propagation in defocusing nonlinear media can mimic the transonic flow of an equivalent fluid, we demonstrate experimentally the formation of an all-…
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…
Effects of nonlinear sweep in the Landau-Zener-Stueckelberg effect
D. A. Garanin, R. Schilling
We study the Landau-Zener-Stueckelberg (LZS) effect for a two-level system with a time-dependent nonlinear bias field (the sweep function) W(t). Our main concern is to investigate…
Inverse problem for the Landau-Zener effect
D. A. Garanin, R. Schilling
We consider the inverse Landau-Zener problem which consists in finding the energy-sweep functions W(t)=E1(t)-E2(t) resulting in the required time dependences of the level populatio…
Dynamical precursor of nematic order in a dense fluid of hard ellipsoids of revolution
Th. Theenhaus, M. Letz, A. Latz +2
We investigate hard ellipsoids of revolution in a parameter regime where no long range nematic order is present but already finite size domains are formed which show orientational…
