In this article, the authors reviewed recent experiments and corresponding theoretical pictures based on the Gross-Pitaevskii equations and the Boltzmann kinetic simulations for a finite-size BEC of polaritons.Abstract:
In the past decade, a two-dimensional matter-light system called the microcavity exciton-polariton has emerged as a new promising candidate of Bose-Einstein condensation BEC in solids. Many pieces of important evidence of polariton BEC have been established recently in GaAs and CdTe microcavities at the liquid helium temperature, opening a door to rich many-body physics inaccessible in experiments before. Technological progress also made polariton BEC at room temperatures promising. In parallel with experimental progresses, theoretical frameworks and numerical simulations are developed, and our understanding of the system has greatly advanced. In this article, recent experiments and corresponding theoretical pictures based on the Gross-Pitaevskii equations and the Boltzmann kinetic simulations for a finite-size BEC of polaritons are reviewed.read more

Graphene/ferroelectrics/graphene hybrid structure: Asymmetric doping of graphene layers
TL;DR: In this paper, an asymmetrical doping in two graphene layers, one side with electrons and another side with holes, was demonstrated by Raman spectroscopy using a poly(vinylidenefluoride-co-trifluoroethylene)(P(VDF-TrFE))/graphene hybrid, which can easily form β-phase close to our simulation model.

Gate-tunable emission of exciton-plasmon polaritons in hybrid MoS2-gap-mode metasurfaces

TL;DR: In this article, the authors couple the excitonic resonance of atomic thin MoS2 monolayers with gap-surface-plasmon (GSP) metasurfaces, and demonstrate selective enhancement of the exciton-polariton polariton emissions by controlling the charge density at interface through electrically gating in MOS structure.

Exact diagonalization studies of quantum simulators
TL;DR: In this paper, the authors present several important examples of quantum systems which can be numerically solved using the exact diagonalization technique, which works solely for systems of a small number of particles and/or available quantum states.

TL;DR: In this paper, the authors investigated the dynamics of an exciton-polariton condensate which emerges in semiconductor microcavity subject to disorder, which determines its spatial and temporal behaviour.

Ordering, metastability and phase transitions in two-dimensional systems
TL;DR: In this article, a new definition of order called topological order is proposed for two-dimensional systems in which no long-range order of the conventional type exists, and the possibility of a phase transition characterized by a change in the response of the system to an external perturbation is discussed in the context of a mean field type of approximation.

TL;DR: In this paper, it is rigorously proved that at any nonzero temperature, a one- or two-dimensional isotropic spin-S$ Heisenberg model with finite-range exchange interaction can be neither ferromagnetic nor antiferromagnetic.

Quantum Phase Transition From a Superfluid to a Mott Insulator in a Gas of Ultracold Atoms
TL;DR: This work observes a quantum phase transition in a Bose–Einstein condensate with repulsive interactions, held in a three-dimensional optical lattice potential, and can induce reversible changes between the two ground states of the system.
