TLDR
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

Polariton trap in microcavities with metallic mirrors.
TL;DR: In planar microcavities with metallic mirrors the spectra of cavity polaritons may be strongly modified by the presence of a surface plasmon interacting with transverse-magnetic (TM)-polarized cavity modes, which may serve as a very effective trap for polariton population at high non-resonant excitation of the cavity.

TL;DR: In this paper , the first halide perovskite polariton light-emitting device is presented, which is based on a CsPbBr3 capacitive structure, which can inject the electrons and holes from the same electrode and simultaneously maintain the high quality of the microcavity.

Van der Waals Heterostructure Polaritons with moir\'e-Induced Nonlinearity
Long Zhang,Fengcheng Wu,Shaocong Hou,Zhe Zhang,Yu Hsun Chou,Kenji Watanabe,Takashi Taniguchi,Stephen R. Forrest,Hui Deng +8 more
TL;DR: In this article, the density dependence of the moir´e polaritons reveals strong nonlinearity due to exciton blockade, suppressed exciton energy shift, and suppressed excitation-induced dephasing, all of which are consistent with the quantum-confined nature of the excitons.

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.

Absence of Ferromagnetism or Antiferromagnetism in One- or Two-Dimensional Isotropic Heisenberg Models
N. D. Mermin,Herbert Wagner +1 more
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.
