Nonadiabatic transitions in Landau-Zener grids: integrability and semiclassical theory
Rajesh K. Malla, Vladimir Y. Chernyak, Nikolai A. Sinitsyn
We demonstrate that the general model of a linearly time-dependent crossing of two energy bands is integrable. Namely, the Hamiltonian of this model has a quadratically time-depend…
Cooperative Light Emission in the Presence of Strong Inhomogeneous Broadening
C. Sun, V. Y. Chernyak, A. Piryatinski +1
We study photon emission by an ensemble of two-level systems, with strong inhomogeneous broadening and coupled to a cavity mode whose frequency has linear time-dependence. The anal…
Dynamic spin localization and gamma-magnets
V. Y. Chernyak, N. A. Sinitsyn, C. Sun
We explore an unusual type of quantum matter that can be realized by qubits having different physical origin. Interactions in this matter are described by essentially different cou…
Low-Temperature Hopping Dynamics with Energy Disorder: Renormalization Group Approach
Kirill A. Velizhanin, Andrei Piryatinski, Vladimir Y. Chernyak
We formulate a real-space renormalization group (RG) approach for efficient numerical analysis of the low-temperature hopping dynamics in energy-disordered lattices. The approach e…
Quantization and Fractional Quantization of Currents in Periodically Driven Stochastic Systems I: Average Currents
Vladimir Y. Chernyak, John R. Klein, Nikolai A. Sinitsyn
This article studies Markovian stochastic motion of a particle on a graph with finite number of nodes and periodically time-dependent transition rates that satisfy the detailed bal…
Quantization and Fractional Quantization of Currents in Periodically Driven Stochastic Systems II: Full Counting Statistics
Vladimir Y. Chernyak, John R. Klein, Nikolai A. Sinitsyn
We study Markovian stochastic motion on a graph with finite number of nodes and adiabatically periodically driven transition rates. We show that, under general conditions, the quan…
