BCS-BEC crossover with a finite-range interaction
Meera M. Parish, Bogdan Mihaila, Eddy M. Timmermans +2
We study the crossover from BEC to BCS pairing for dilute systems but with a realistic finite-range interaction. We exhibit the changes in the excitation spectrum that provide a cl…
The Electron Glass in a Switchable Mirror: Relaxation, Aging and Universality
M. Lee, P. Oikonomou, P. Segalova +3
The rare earth hydride YH can be tuned through the metal-insulator transition both by changing and by illumination with ultraviolet light. The transition is dominated b…
Effects of Disorder on Coexistence and Competition between Superconducting and Insulating States
M. V. Mostovoy, F. M. Marchetti, B. D. Simons +1
We study effects of nonmagnetic impurities on the competition between the superconducting and electron-hole pairing. We show that disorder can result in coexistence of these two ty…
Models of coherent exciton condensation
P. B. Littlewood, P. R. Eastham, J. M. J. Keeling +3
That excitons in solids might condense into a phase-coherent ground state was proposed about 40 years ago, and has been attracting experimental and theoretical attention ever since…
Polariton condensation with localised excitons and propagating photons
Jonathan Keeling, P. R. Eastham, M. H. Szymanska +1
We estimate the condensation temperature for microcavity polaritons, allowing for their internal structure. We consider polaritons formed from localised excitons in a planar microc…
Condensation of Cavity Polaritons in a Disordered Environment
F. M. Marchetti, B. D. Simons, P. B. Littlewood
A model for direct two band excitons in a disordered quantum well coupled to light in a cavity is investigated. In the limit in which the exciton density is high, we assess the imp…
