A High Phase-Space-Density Gas of Polar Molecules
K. -K. Ni, S. Ospelkaus, M. H. G. de Miranda +7
A quantum gas of ultracold polar molecules, with long-range and anisotropic interactions, would not only enable explorations of a large class of many-body physics phenomena, but co…
Observation of an ultracold plasma instability
X. L. Zhang, R. S. Fletcher, S. L. Rolston
We present the first observation of an instability in an expanding ultracold plasma. We observe periodic emission of electrons from an ultracold plasma in weak, crossed magnetic an…
Orbital fluctuation mechanism for superconductivity in iron-based compounds
Tudor D. Stanescu, Victor Galitski, S. Das Sarma
We propose orbital fluctuations in a multi-band ground state as the superconducting pairing mechanism in the new iron-based materials. We develop a general SU(4) theoretical framew…
Intrinsic and Fundamental Decoherence: Issues and Problems
C. Anastopoulos, B. L. Hu
We investigate the meaning of gravity-induced decoherence in quantum theory, known as `intrinsic' or `fundamental' decoherence in the literature. We explore a range of issues relev…
Quantum decoherence of a charge qubit in a spin-fermion model
R. M. Lutchyn, L. Cywinski, Cody P. Nave +1
We consider quantum decoherence in solid-state systems by studying the transverse dynamics of a single qubit interacting with a fermionic bath and driven by external pulses. Our in…
