Generalized Almost Complete Revivals in quantum spin chains
Igor Ermakov
The conception of almost complete revivals has been introduced recently. In a quantum many-body system local observable may exhibit an almost complete revival to its maximal value…
Almost complete revivals in quantum many-body systems
Igor Ermakov, Boris V. Fine
Revivals of initial non-equilibrium states is an ever-present concern for the theory of dynamic thermalization in many-body quantum systems. Here we consider a nonintegrable lattic…
Testing eigenstate decoherence hypothesis in a model of collisional decoherence
Ivan V. Dudinets, Igor Ermakov, Oleg Lychkovskiy
The eigenstate decoherence hypothesis (EDH) asserts that each individual eigenstate of a large closed system is locally classical-like. We test this hypothesis for a heavy particle…
Cooper pair polaritons in cold fermionic atoms within a cavity
Amaury Dodel, Alexander Pikovski, Igor Ermakov +4
We formulate a Bardeen-Cooper-Schriffer (BCS) theory of quasiparticles in a degenerate Fermi gas strongly coupled to photons in a optical cavity. The elementary photonic excitation…
Time dynamics of Bethe ansatz solvable models
Igor Ermakov, Tim Byrnes
We develop a method for finding the time evolution of exactly solvable models by Bethe ansatz. The dynamical Bethe wavefunction takes the same form as the stationary Bethe wavefunc…
High accuracy energy formulas for the attractive two-site Bose-Hubbard model
Igor Ermakov, Tim Byrnes, Nikolay Bogoliubov
The attractive two-site Bose-Hubbard model is studied within the framework of the analytical solution obtained by the application of Quantum Inverse Scattering Method. The structur…
