Frustrated three-leg spin tubes: from spin 1/2 with chirality to spin 3/2
J. -B. Fouet, A. Laeuchli, S. Pilgram +2
Motivated by the recent discovery of the spin tube [(CuCltachH)Cl]Cl, we investigate the properties of a frustrated three-leg spin tube with antiferromagnetic intra-rin…
Molecules of Fermionic Atoms in an Optical Lattice
Thilo Stöferle, Henning Moritz, Kenneth Günter +2
We create molecules from fermionic atoms in a three-dimensional optical lattice using a Feshbach resonance. In the limit of low tunnelling, the individual wells can be regarded as…
Magnetic Phase Transition at 88 K in Na0.5CoO2 revealed by 23Na-NMR investigations
B. Pedrini, J. L. Gavilano, S. Weyeneth +6
Na0.5CoO2 exhibits a metal-insulator transition at 53 K upon cooling. The nature of another transition at 88 K has not been fully clarified yet. We report the results of measuremen…
d-wave resonating valence bond states of fermionic atoms in optical lattices
Simon Trebst, Ulrich Schollwoeck, Matthias Troyer +1
We study controlled generation and measurement of superfluid d-wave resonating valence bond (RVB) states of fermionic atoms in 2D optical lattices. Starting from loading spatial an…
Atomic quantum simulator for lattice gauge theories and ring exchange models
H. P. Büchler, M. Hermele, S. D. Huber +2
We present the design of a ring exchange interaction in cold atomic gases subjected to an optical lattice using well understood tools for manipulating and controlling such gases. T…
Supersolids versus phase separation in two-dimensional lattice bosons
Pinaki Sengupta, Leonid P. Pryadko, Fabien Alet +2
We study the nature of the ground state of the strongly-coupled two dimensional extended boson Hubbard model on a square lattice. We demonstrate that strong but finite on-site inte…
