Polaritons are quasiparticles that form in semiconductors when an elementary excitation
such as an exciton or a phonon interacts sufficiently strongly with light. In particular, exciton …

Polaritons are quasi-particles that originate from the coupling of light with matter and that
demonstrate quantum phenomena at the many-particle mesoscopic level, such as Bose …

We apply our recently developed theory of frequency-filtered and time-resolved N-photon
correlations (del Valle et al 2012 Phys. Rev. Lett. 109 183601) to study the two-photon …

We discuss the excitation of polaritons—strongly coupled states of light and matter—by
quantum light, instead of the usual laser or thermal excitation. As one illustration of the new …

Optical parametric oscillators (OPOs) have been widely applied in spectroscopy, squeezed
light, and correlated photons, as well as quantum information. Conventional OPOs usually …

Nonequilibrium patterns in open systems are ubiquitous in nature, with examples as diverse
as desert sand dunes, animal coat patterns such as zebra stripes, or geographic patterns in …

Semiconductor devices are strong competitors in the race for the development of quantum
computational systems. In this work, we interface two semiconductor building blocks of …

Multi-level exciton-polariton systems offer an attractive platform for studies of non-linear
optical phenomena. However, studies of such consequential non-linear phenomena as …

Superfluidity, which is the ability of a liquid or gas to flow with zero viscosity, is one of the
most remarkable implications of collective quantum coherence. In equilibrium systems such …

We consider a polariton microcavity resonantly driven by two external lasers which
simultaneously pump both lower and upper polariton branches at normal incidence. In this …
