Inhomogeneous magnetic phases: a LOFF-like phase in Sr3Ru2O7 (2008)
Berridge, A. M., Green, A. G., Grigera, S. A., Simons, B. D.
The phase diagram of Sr3Ru2O7 contains a metamagnetic transition that bifurcates to enclose an anomalous phase with intriguing properties - a large resistivity with anisotropy that breaks the...
Conduit, G. J., Conlon, P. H., Simons, B. D.
We explore the zero temperature phase behavior of a two-dimensional two-component atomic Fermi gas with population and mass imbalance in the regime of the BEC-BCS crossover. Working in the mean-field...
Coexistence of SDW, d-wave singlet and staggered $\pi$-triplet superconductivity (2008)
Aperis, A., Varelogiannis, G., Littlewood, P. B., Simons, B. D.
We have studied the competition and coexistence of staggered triplet SC with d-wave singlet SC and SDW in the mean-field approximation. Detailed numerical studies demonstrate that particle-hole...
Probing ultra-cold Fermi atoms with a single ion (2008)
Sherkunov, Y., Muzykantskii, B., D'Ambrumenil, N., Simons, B. D
We study an ion held in a Paul trap in an atomic Fermi gas and compute the two-photon Raman photo-association rate of the ion and an atom. We show, that, as a function of the detunings between the...
Pattern Formation in Exciton System near Quantum Degeneracy (2005)
Levitov, L S, Simons, B D, Butov, L V
We discuss models of the modulational instability in a cold exciton system in coupled quantum wells. One mechanism involves exciton formation in a photoexcited electron-hole system in the presence of...
Mostovoy, M.V., Marchetti, F.M., Simons, B.D., Littlewood, P.B.
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 types of ordering in...
Pattern Formation as a Signature of Quantum Degeneracy in a Cold Exciton System (2004)
Levitov, L. S., Simons, B. D., Butov, L. V.
The development of a Turing instability to a spatially modulated state in a photoexcited electron-hole system is proposed as a novel signature of exciton Bose statistics. We show that such an...
Charge transport and phase transition in exciton rings (2003)
Butov, L. V., Levitov, L. S., Mintsev, A. V., Simons, B. D., Gossard, A. C., Chemla, D. S.
The macroscopic exciton rings observed in the photoluminescence (PL) patterns of excitons in coupled quantum wells (CQWs) are explained by a series of experiments and a theory based on the idea of...
Quantized Adiabatic Charge Transport in a Carbon Nanotube (2001)
Talyanskii, V. I., Novikov, Dmitry, Simons, B. D., Levitov, L. S.
The coupling of a metallic Carbon nanotube to a surface acoustic wave (SAW) is proposed as a vehicle to realize quantized adiabatic charge transport in a Luttinger liquid system. We demonstrate that...
