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

Cavity-assisted boosting of self-hybridization between excitons and photonic bound states in the continuum in multilayers of transition metal dichalcogenides
TL;DR: In this paper , a cavity-assisted boosting of self-hybridization between excitons and quasibounded states in the continuum (QBIC) was reported by embedding a two-dimensional (2D) metasurface composed of bulk metal dichalcogenides into a microcavity.

Multi-dimensional laser spectroscopy of exciton polaritons with spatial light modulators
P. Mai,B. Pressl,M. Sassermann,Z. Vörös,Gregor Weihs,Christian Schneider,Andreas Löffler,Sven Höfling,Alfred Forchel +8 more
TL;DR: In this article, an experimental system that allows one to easily access the dispersion curve of exciton-polaritons in a microcavity is described. But this system is based on two spatial light modulators, one for changing the excitation angles (momenta), and the other for tuning the excitations wavelength.

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.

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.
