Three-Dimensional Kardar--Parisi--Zhang Scaling in Polariton Condensates
Junhui Cao, Denis Novokreschenov, Artem Alexandrov +2
Kardar--Parisi--Zhang (KPZ) universality provides an example of macroscopic scaling generated by microscopic violation of detailed balance. While one- and two-dimensional realizati…
The origin of KPZ-scaling in arrays of polariton condensates
Denis Novokreschenov, Alexey Kavokin
This work investigates the origin of Kardar-Parisi-Zhang (KPZ) scaling in the phase dynamics of one-dimensional and two-dimensional polariton condensates. We demonstrate that the k…
Polariton XY-simulators revisited
Junhui Cao, Denis Novokreschenov, Alexey Kavokin
Arrays of bosonic condensates of exciton-polaritons have emerged as a promising platform for simulating classical XY models, capable of rapidly reaching phase-locked states that ma…
Classical and single photon memory devices based on polariton lasers
D. Novokreschenov, A. Kudlis, A. V. Kavokin
Stimulated scattering of incoherent excitons into an exciton-polariton mode leads to the build-up of a polariton condensate whose polarization is sensitive to a small seeded popula…
Kardar-Parisi-Zhang universality in optically induced lattices of exciton-polariton condensates
D. Novokreschenov, V. Neplokh, M. Misko +7
We investigate space-time coherence in one-dimensional lattices of exciton-polariton condensates formed by fully reconfigurable non-resonant optical pumping. Starting from an open-…
Extended XY model for spinor polariton simulators
A. Kudlis, D. Novokreschenov, I. A. Shelykh
The classic lattice XY model is one of the universal models of statistical mechanics appearing in a broad variety of optical and condensed matter systems. One of its possible reali…
Quantum beats of a macroscopic polariton condensate in real space
R. V. Cherbunin, A. Liubomirov, D. Novokreschenov +2
We experimentally observe harmonic oscillations in a bosonic condensate of exciton-polaritons confined within an elliptical trap. These oscillations arise from quantum beats betwee…
Quantum electrodynamical density functional theory for generalized Dicke model
A. Kudlis, D. Novokreschenov, I. Iorsh +1
We formulate and analyze in detail the ground state quantum electrodynamical density functional theory (QEDFT) for a generalized Dicke model describing a collection of tight-bi…
Non-perturbative effects of deep-strong light-matter interaction in a mesoscopic cavity-QED system
Andrey Kudlis, Denis Novokreschenov, Ivan Iorsh +1
We consider a system comprising two groups of quantum dimers placed in a common electromagnetic cavity, and controlled by selectively applying a static external potential to one of…
