Commensurate Two-Component Bosons in an Optical Lattice: Ground State Phase Diagram
Bosons optical lattice superfluid quantum systems and quantum
2014/12/20
Two sorts of bosons in an optical lattice at commensurate filling factors can form five stable superfluid and insulating ground states with rich and nontrivial phase diagram. The structure of the grou...

2014/5/28
We present a feasible scheme for the cooling of a mechanical resonator via projective measurements on an auxiliary flux qubit which interacts with it. We find that ground-state cooling can be achieved...
Opportunities to constrain astrophysical reaction rates for the s-process through determination of the ground state cross sections
