  • Antiferromagnetic heisenberg spin chain of a few cold atoms in a one-dimensional trap 
    Murmann, S.; Deuretzbacher, Frank; Zürn, G.; Bjerlin, J.; Reimann, S.M.; Santos, Luis; Lompe, T.; Jochim, S. (College Park, MD : American Physical Society, 2015)
    We report on the deterministic preparation of antiferromagnetic Heisenberg spin chains consisting of up to four fermionic atoms in a one-dimensional trap. These chains are stabilized by strong repulsive interactions between ...
  • Simulating circuits with impasse points 
    Thiessen, Tina; Mathis, Wolfgang (Göttingen : Copernicus GmbH, 2013)
    In this paper circuits with impasse points, i.e. with jumps in their configuration space will be analyzed. These non-regularized circuits exhibit a fold in their configuration space, which can lead to difficulties during ...
  • Smallest state spaces for which bipartite entangled quantum states are separable 
    Anwar, H.; Jevtic, S.; Rudolph, O.; Virmani, S. (Bristol : Institute of Physics Publishing, 2015)
    According to usual definitions, entangled states cannot be given a separable decomposition in terms of products of local density operators. If we relax the requirement that the local operators be positive, then an entangled ...
  • Spin-chain model for strongly interacting one-dimensional Bose-Fermi mixtures 
    Deuretzbacher, Frank; Becker, D.; Bjerlin, J.; Reimann, S.M.; Santos, Luis (College Park, MD : American Physical Society, 2017)
    Strongly interacting one-dimensional (1D) Bose-Fermi mixtures form a tunable XXZ spin chain. Within the spin-chain model developed here, all properties of these systems can be calculated from states representing the ordering ...
  • Unconventional phases of attractive Fermi gases in synthetic Hall ribbons 
    Ghosh, Sudeep Kumar; Greschner, Sebastian; Yadav, Umesh K.; Mishra, Tapan; Rizzi, Matteo; Shenoy, Vijay B. (College Park, MD : American Physical Society, 2017)
    An innovative way to produce quantum Hall ribbons in a cold atomic system is to use M hyperfine states of atoms in a one-dimensional optical lattice to mimic an additional "synthetic dimension." A notable aspect here is ...
  • Unraveling Two-Photon Entanglement via the Squeezing Spectrum of Light Traveling through Nanofiber-Coupled Atoms 
    Hinney, Jakob; Prasad, Adarsh S.; Mahmoodian, Sahand; Hammerer, Klemens; Rauschenbeutel, Arno; Schneeweiss, Philipp; Volz, Jürgen; Schemmer, Max (College Park, Md. : APS, 2021)
    We observe that a weak guided light field transmitted through an ensemble of atoms coupled to an optical nanofiber exhibits quadrature squeezing. From the measured squeezing spectrum we gain direct access to the phase and ...
