Integrable multistate Landau-Zener models with parallel energy levels
Vladimir Y. Chernyak, Fuxiang Li, Chen Sun +1
We discuss solvable multistate Landau-Zener (MLZ) models whose Hamiltonians have commuting partner operators with -time-dependent parameters. Many already known solvable…

Multitime Landau-Zener model: classification of solvable Hamiltonians
Vladimir Y. Chernyak, Nikolai A. Sinitsyn, Chen Sun
We discuss a class of models that generalize the two-state Landau-Zener (LZ) Hamiltonian to both the multistate and multitime evolution. It is already known that the corresponding…
