Quantum phases and entanglement properties of an extended Dicke model
We study a simple model describing superradiance in a system of two-level atoms interacting with a single-mode bosonic field. The model permits a continuous crossover between integrable and partially chaot...

Monodromy in Dicke superradiance
We study the focus-focus type of monodromy in an integrable version of the Dicke model. Classical orbits forming a pinched torus represent analogues of the dynamic superradiance under conditions of a closed system. Quantum signature...

Stabilization of product states and excited-state quantum phase transitions in a coupled qubit-field system
We study a system of a single qubit (or a few qubits) interacting with a soft-mode bosonic field. Considering an extended version of the Rabi model with both in the ultrastrong coupling regime where the superradiant

Superradiance in finite quantum systems randomly coupled to continuum
We study the effect of superradiance in open quantum systems, i.e., the separation of short- and long-living eigenstates when a certain subspace of states of an effective non-Hermitian Hamiltonian and relate robust features of the superr...

Interference of Single Photons Emitted by Entangled Atoms in Free Space
the control of the emission rate of a single photon from a pair of distant, entangled atoms into a free-space optical mode. Changing the length of the optical path connecting the atoms modulates the single-photon emission ...

Collective Luminescence and Phonon-Induced Processes in Double Quantum Dots
We study the evolution of a quantum state of a double quantum dot system interacting with the electromagmetic environment and with the lattice modes, in the presence of a coupling between the two dots. We propose a unified approach the sub- ...
