    • Bloch oscillations of bosonic lattice polarons 

      Grusdt, Fabian; Shashi, A.; Abanin, Dmitry; Demler, Eugene A. (American Physical Society (APS), 2014)
      We consider a single-impurity atom confined to an optical lattice and immersed in a homogeneous Bose-Einstein condensate (BEC). Interaction of the impurity with the phonon modes of the BEC leads to the formation of a stable ...
    • A cold-atom Fermi–Hubbard antiferromagnet 

      Mazurenko, Anton; Chiu, Christie Shinglei; Parsons, Maxwell Fredrick; Kanasz-Nagy, Marton; Schmidt, Richard; Grusdt, Fabian; Demler, Eugene A.; Greif, Daniel Guenther; Greiner, Markus (Springer Nature, 2017)
      Exotic phenomena in strongly correlated electron systems emerge from the interplay between spin and motional degrees of freedom. For example, doping an antiferromagnet is expected to give rise to pseudogap states and ...
    • Imaging Magnetic Polarons in the Doped Fermi–Hubbard Model 

      Demler, Eugene; Koepsell, Joannis; Vijayan, Jayadev; Sompet, Pimonpan; Bohrdt Grusdt, Fabian; Hilker, Timon A.; Demler, Eugene; Salomon, Guillaume; Bloch, Immanuel; Gross, Christian (Springer Science and Business Media LLC, 2019-08-14)
      Polarons are among the most fundamental quasiparticles emerging in interacting many-body systems, forming already at the level of a single mobile dopant [1]. In the context of the two- dimensional ...
    • Measuring Z 2 topological invariants in optical lattices using interferometry 

      Grusdt, Fabian; Abanin, Dmitry; Demler, Eugene A. (American Physical Society (APS), 2014)
      We propose an interferometric method to measure ℤ2 topological invariants of time-reversal invariant topological insulators realized with optical lattices in two and three dimensions. We suggest two schemes which both rely ...
    • Radio-frequency spectroscopy of polarons in ultracold Bose gases 

      Shashi, Aditya; Grusdt, Fabian; Abanin, Dmitry; Demler, Eugene A. (American Physical Society (APS), 2014)
      Recent experimental advances enabled the realization of mobile impurities immersed in a Bose-Einstein condensate (BEC) of ultracold atoms. Here, we consider impurities with two or more internal hyperfine states, and study ...
