Topological semimetal: a probable new state of quantum optical lattice gases protected by D$_4$ symmetry
Topological semimetal quantum optical lattice gases

The use of optical lattices plays a versatile role in advancing knowledge of correlated quantum
matter. The recent orbital lattice experimentsof Wirth et al [1{3] open up a new thrust towards
discov...

We study a three-components fermionic gas loaded in a one-dimensional optical trap at half-
lling. We nd that the system is fully gapped and may order into 8 possible phases: four 2kF
atomic densi...

We study a system of ultra-cold atoms possessing long range interaction (e.g. dipole-dipole interaction)in a one dimensional optical lattice in the presence of a confining harmonic trap. We have shown...
