Ultrafast Nonequilibrium Dynamics in Two-dimensional Quantum Spin-Hall Materials
Rajesh K. Malla, Dasol Kim, Dong Eon Kim +2
We develop the theoretical framework of nonequilibrium ultrafast photonics in monolayer quantum spin-Hall insulators supporting a multitude of topological states. In these material…
Landau-Zener transition between two levels coupled to continuum
Rajesh K. Malla, M. E. Raikh
For a Landau-Zener transition in a two-level system, the probability for a particle, initially in the first level, {\em i}, to survive the transition and to remain in the first lev…
Effect of decay of the final states on the probabilities of the Landau-Zener transitions in multistate non-integrable models
Rajesh K. Malla, M. E. Raikh
For a Landau-Zener transition in a two-level system, the probability for a particle, initially in the first level, to survive the transition and to remain in the first level, does…
Nonadiabatic dissociation of molecular Bose-Einstein condensates: competition between chemical reactions
Rajesh K. Malla
We provide a framework to solve generic models describing the dissociation of multiple molecular Bose-Einstein condensates in a nonadiabatic regime. The competition between individ…
Coherent reaction between molecular and atomic Bose-Einstein condensates: integrable model
Rajesh K. Malla, Vladimir Y. Chernyak, Chen Sun +1
We solve a model that describes a stimulated conversion between ultracold bosonic atoms and molecules. The reaction is triggered by a linearly time-dependent transition throughout…
