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…
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…
Universality of Parametric Spectral Correlations: Local versus Extended Perturbing Potentials
F. M. Marchetti, I. E. Smolyarenko, B. D. Simons
We explore the influence of an arbitrary external potential perturbation V on the spectral properties of a weakly disordered conductor. In the framework of a statistical field theo…
Field Theory of Mesoscopic Fluctuations in Superconductor/Normal-Metal Systems
Alexander Altland, B. D. Simons, D. Taras-Semchuk
Thermodynamic and transport properties of mesoscopic conductors are strongly influenced by the proximity of a superconductor: An interplay between the large scale quantum coherent…
