Scientific News1 January 2018|ILP SengstockSymmetry-broken momentum distributions induced by matter-wave diffraction during time-of-flight expansion of ultracold atomsPhoto: AG SengstockWe study several effects which lead to symmetry-broken momentum distributions of quantum gases released from optical lattices. In particular, we...6 July 2017|ILP SengstockTime-reversal symmetry breaking in 1D superfluidsPhoto: AG SengstockWe found a superfluid which spontaneously breaks the time-reversal symmetry in one-dimensional optical lattices. This twisted superfluid is...1 May 2016|ILP SengstockSchwerelos: Generalprobe auf Forschungsrakete bestandenPhoto: AG SengstockEin von Wissenschaftlerinnen und Wissenschaftlern der Universität Hamburg mitentwickeltes System für präzisionsspektroskopische Anwendungen im...1 December 2015|ILP SengstockBreaking inversion symmetry in a state-dependent honeycomb lattice: Artificial graphene with tunable band gapPhoto: AG SengstockWe present the application of a novel method for controlling the geometry of a state-dependent honeycomb lattice: The energy offset between the two...12 May 2015|ILP SengstockMultiphoton interband excitations of quantum gases in driven optical latticesPhoto: AG SengstockPeriodically driven quantum systems, so called Floquet systems, are described by a time-independent effective Hamiltonian. This allows for realizing...8 July 2014|ILP SengstockSpin Orbit Coupling in Periodically Driven Optical LatticesPhoto: AG SengstockWe propose a novel experimental scheme for the emulation of spin-orbit coupling for ultracold, neutral atoms trapped in a one-dimensional lattice...24 January 2014|ILP SengstockQuantum phases in tunable state-dependent hexagonal optical latticesPhoto: AG SengstockWe study the ground-state properties of ultracold bosonic atoms on a state-dependent graphene-like honeycomb lattice. We discuss the various...6 July 2013|ILP SengstockLarge-Amplitude Superexchange of High-Spin Fermions in Optical LatticesPhoto: AG SengstockWe show that fermionic high-spin systems with spin-changing collisions allow to monitor superexchange processes in optical superlattices with large...22 April 2013|ILP SengstockEngineering Ising-XY spin models in a triangular lattice via tunable artificial gauge fieldsPhoto: AG SengstockEmulation of gauge fields for ultracold atoms provides access to a class of exotic states arising in strong magnetic fields. Here we report on the...3 April 2013|ILP SengstockCluster Gutzwiller for bosons in optical latticesPhoto: AG SengstockBy treating clusters within the Gutzwiller theory, a surprisingly good description of quantum fluctuations beyond the mean-field theory is achieved...Show all news
