Unusual compressibility in the negative-thermal-expansion material ZrW2O8
C. Pantea, A. Migliori, P. B. Littlewood +5
The negative thermal expansion (NTE) compound ZrW2O8 has been well-studied because it remains cubic with a nearly constant, isotropic NTE coefficient over a broad temperature range…
Thermodynamics and Excitations of Condensed Polaritons in Disordered Microcavities
F. M. Marchetti, J. Keeling, M. H. Szymanska +1
We study the thermodynamic condensation of microcavity polaritons using a realistic model of disorder in semiconductor quantum wells. This approach correctly describes the polarito…
BCS-BEC crossover in a system of microcavity polaritons
Jonathan Keeling, P. R. Eastham, M. H. Szymanska +1
We investigate the thermodynamics and signatures of a polariton condensate over a range of densities, using a model of microcavity polaritons with internal structure. We determine…
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…
