Exciton-polariton ring Josephson junction
Nina Voronova, Anna Grudinina, Riccardo Panico +6
Macroscopic coherence in quantum fluids allows the observation of interference effects in their wavefunctions, and enables applications such as superconducting quantum interference…
Tunable Bose-Einstein condensation and roton-like excitation spectra with dipolar exciton-polaritons in crossed fields
Timofey V. Maximov, Igor L. Kurbakov, Nina S. Voronova +1
We develop the many-body theory of dipolar exciton-polaritons in an optical microcavity in crossed transverse electric and in-plane magnetic fields. Even for relatively weak fields…
Coupled system of electrons and exciton-polaritons: Screening, dynamical effects, and superconductivity
Andrey S. Plyashechnik, Alexey A. Sokolik, Nina S. Voronova +1
Bose-Fermi systems such as mixtures of electrons with excitons or exciton-polaritons are extensively discussed as candidates to host a variety of intriguing phenomena, including po…
Topologically driven Rabi-oscillating interference dislocation
Amir Rahmani, David Colas, Nina Voronova +3
Quantum vortices are the quantized version of classical vortices. Their center is a phase singularity or vortex core around which the flow of particles as a whole circulates and is…
Coupled quantum vortex kinematics and Berry curvature in real space
Lorenzo Dominici, Amir Rahmani, David Colas +6
The Berry curvature provides a powerful tool to unify several branches of science through their geometrical aspect: topology, energy bands, spin and vector fields. While quantum de…
Shaping the topology of light with a moving Rabi-oscillating vortex
Lorenzo Dominici, Nina Voronova, David Colas +8
Quantum vortices are the analogue of classical vortices in optics, Bose-Einstein condensates, superfluids and superconductors, where they provide the elementary mode of rotation an…
Finite-temperature Hatree-Fock-Bogoliubov theory for exciton-polaritons
A. M. Grudinina, I. L. Kurbakov, Yu. E. Lozovik +1
Microcavity exciton-polaritons, known to exhibit non-equilibrium Bose condensation at high critical temperatures, can be also brought in thermal equilibrium with the surrounding me…
Bose condensation of direct excitons in an off-resonant cavity at elevated temperatures
Nina S. Voronova, Igor L. Kurbakov, Yurii E. Lozovik
We propose a way to increase the lifetime of two-dimensional direct excitons and show the possibility to observe their macroscopically coherent state at high temperatures. For a si…
Inverted pendulum state of a polariton Rabi oscillator
Nina S. Voronova, Andrei A. Elistratov, Yurii E. Lozovik
Exciton-photon beats known as polariton Rabi oscillations in semiconductor microcavities are usually excited by short pulses of light. We consider a different pumping scheme, assum…
Detuning-controlled internal oscillations in an exciton-polariton condensate
Nina Voronova, Andrei Elistratov, Yurii Lozovik
We theoretically analyze exciton-photon oscillatory dynamics within a homogenous polariton gas in presence of energy detuning between the cavity and quantum well modes. Whereas pur…
Internal Josephson phenomena in a coupled two-component Bose condensate
N. S. Voronova, Yu. E. Lozovik
We discuss the coherent oscillations between two coupled quantum states of a Bose-Einstein condensate in two-dimensional space at zero temperature. In the system we consider, weak…
