Employing a novel...21 July 2011|ILP SengstockQuantum Simulation of Frustrated Classical Magnetism in Triangular Optical LatticesPhoto: AG SengstockWe present the first realization of a large scale quantum simulator for classical magnetism in a triangular optical lattice. Via a specific modulation...18 April 2011|ILP SengstockQuantum phase transition to unconventional multi-orbital superfluidity in optical latticesPhoto: AG SengstockWe observe a novel multi-orbital superfluid phase with a complex order parameter in binary spin mixtures. In this unconventional superfluid, the local...13 February 2011|ILP SengstockMulti-Component Quantum Gases in Spin-Dependent Hexagonal LatticesPhoto: AG SengstockIn solid state materials hexagonal structures play an extremely important role and lead to novel physics like that of carbon nanotubes or graphene...
