Finite-size fluctuations and photon statistics near the polariton condensation transition in a single-mode microcavity
P. R. Eastham, P. B. Littlewood
We consider polariton condensation in a generalized Dicke model, describing a single-mode cavity containing quantum dots, and extend our previous mean-field theory to allow for fin…
Transformation of spin information into large electrical signals via carbon nanotubes
Luis E. Hueso, Jose M. Pruneda, Valeria Ferrari +7
Spin electronics (spintronics) exploits the magnetic nature of the electron, and is commercially exploited in the spin valves of disc-drive read heads. There is currently widesprea…
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…
Classical magnetotransport of inhomogeneous conductors
Meera M. Parish, Peter B. Littlewood
We present a model of magnetotransport of inhomogeneous conductors based on an array of coupled four-terminal elements. We show that this model generically yields non-saturating ma…
Solitonic Phase in Manganites
Luis Brey, P. B. Littlewood
Whenever a symmetry in the ground state of a system is broken, topological defects will exist. These defects are essential for understanding phase transitions in low dimensional sy…
