Abstract The study of Bose–Einstein condensation effects in photonic systems has revealed
a rich phenomenology related to spontaneous coherence generation in driven-dissipative …

An exciton is the particle-like entity that forms when an electron is bound to a positively
charged 'hole'. An ordered electronic state in which excitons condense into a single …

An exciton is the bosonic quasiparticle of electron–hole pairs bound by the Coulomb
interaction. Bose–Einstein condensation of this exciton state has long been the subject of …

The nanoscale periodic potentials introduced by moiré patterns in semiconducting van der
Waals heterostructures have emerged as a platform for designing exciton superlattices …

Excitons (coupled electron–hole pairs) in semiconductors can form collective states that
sometimes exhibit spectacular nonlinear properties. Here, we show experimental evidence …

Heterostructures comprising different monolayer semiconductors provide an attractive
setting for fundamental science and device technologies, such as in the emerging field of …

We directly monitor exciton propagation in freestanding and SiO 2-supported WS 2
monolayers through spatially and time-resolved microphotoluminescence under ambient …

Phase transitions to quantum condensed phases—such as Bose–Einstein condensation
(BEC), superfluidity, and superconductivity—have long fascinated scientists, as they bring …

Microcavities are semiconductor, metal, or dielectric structures providing optical confinement
in one, two or three dimensions. At the end of the 20th century, microcavities have attracted …

We show that, because of the inevitable twist and lattice mismatch in heterobilayers of
transition metal dichalcogenides, interlayer excitons have sixfold degenerate light cones …
