Fine Structure of Rydberg Excitons in Cuprous Oxide
- PhysicsPhysics of the Solid State
In 1952, E.F. Gross and N.A. Karryev discovered excitons of big radius also called the Wannier–Mott excitons. Their energy spectrum, response to external electric and magnetic fields, and also…

Polaritons in cuprous oxide perturbed by LA-phonons
We present a comparative analysis of a 'conventional' phonoriton (coherent superposition of exciton-photon-phonon) and a polariton (coherent exciton-photon superposition) 'weakly' coupled to the…
Photonic band mixing in linear chains of optically coupled microspheres.
- PhysicsPhysical review. E, Statistical, nonlinear, and soft matter physics
Bands resulting from hybridization of excitations resulting from whispering gallery modes with different parity of l exhibits anomalous dispersion properties characterized by a gap in the allowed values of wave numbers and divergence of group velocity.
Heavy photon states in photonic chains of resonantly coupled cavities with supermonodispersive microspheres.
- PhysicsPhysical review letters
A "bottom-up" approach to constructing photonic structures for photon manipulation using supermonodispersive polymer microspheres and an excellent agreement with a tight-binding model calculation is found.
Microcavities combining a semiconductor with a fused-silica microsphere.
- PhysicsOptics letters
We report studies of a novel microcavity system that combines a semiconductor quantum well with a fused-silica microsphere. We show that excitonic photoluminescence from the quantum well couples…
Optical resonances and two-sphere systems.
- PhysicsApplied optics
A theoretical investigation of the effects of interparticle coupling on morphology-dependent resonances of spheres is conducted and Calculations are presented of resonance spectra for selected orientations of the bispheres relative to the incident wave vector along with spectra that should prove useful in describing the scattering properties of a monodisperse ensemble of randomly oriented bisphere.
Bose–Einstein condensation of exciton polaritons
A comprehensive set of experiments giving compelling evidence for BEC of polaritons of bosonic quasi-particles are detailed, which indicate the spontaneous onset of a macroscopic quantum phase.
Exciton-photon strong-coupling regime for a single quantum dot embedded in a microcavity.
- PhysicsPhysical review letters
We report on the observation of the strong-coupling regime between the excitonic transition of a single GaAs quantum dot and a discrete optical mode of a microdisk microcavity. Photoluminescence is…
Ab initio tight-binding description of morphology-dependent resonance in a bisphere
Morphology-dependent resonance (MDR) of the electric field in a bisphere is investigated with respect to the electromagnetic energy stored within the spheres. The energy spectra clearly reveal the…
Quantum saturation and condensation of excitons in Cu2O: A theoretical study.
- PhysicsPhysical review. B, Condensed matter
It is shown that the ortho excitons move along the phase boundary without crossing it (i.e., they exhibit a ``quantum saturation''), as a consequence of the balance of entropy changes due to cooling of exciton by phonons and heating by the nonradiative Auger two-exciton recombination process.
