Fractional corner charges in a 2D super-lattice Bose-Hubbard model
Julian Bibo, Izabella Lovas, Yizhi You +2
We study a two dimensional super-lattice Bose-Hubbard model with alternating hoppings in the limit of strong on-site interactions. We evaluate the phase diagram of the model around…
Evaluation of time-dependent correlators after a local quench in iPEPS: hole motion in the t-J model
C. Hubig, A. Bohrdt, M. Knap +2
Infinite projected entangled pair states (iPEPS) provide a convenient variational description of infinite, translationally-invariant two-dimensional quantum states. However, the si…
Z2 characterization for three-dimensional multiband Hubbard models
Bernhard Irsigler, Jun-Hui Zheng, Fabian Grusdt +1
We introduce three numerical methods for characterizing the topological phases of three-dimensional multiband Hubbard models based on twisted boundary conditions, Wilson loops, as…
Multiparticle interactions for ultracold atoms in optical tweezers: Cyclic ring-exchange terms
Annabelle Bohrdt, Ahmed Omran, Eugene Demler +2
Dominant multi-particle interactions can give rise to exotic physical phases with anyonic excitations and phase transitions without local order parameters. In spin systems with a g…
Confined phases of one-dimensional spinless fermions coupled to gauge theory
Umberto Borla, Ruben Verresen, Fabian Grusdt +1
We investigate a quantum many-body lattice system of one-dimensional spinless fermions interacting with a dynamical gauge field. The gauge field mediates long-range attractio…
Dynamical formation of a magnetic polaron in a two-dimensional quantum antiferromagnet
Annabelle Bohrdt, Fabian Grusdt, Michael Knap
We numerically study the real-time dynamics of a single hole created in the model on a square lattice. Initially, the hole spreads ballistically with a velocity proportional…
Dissipative correlated dynamics of a moving impurity immersed in a Bose-Einstein Condensate
S. I. Mistakidis, F. Grusdt, G. M. Koutentakis +1
We unravel the nonequilibrium correlated quantum quench dynamics of an impurity traveling through a harmonically confined Bose-Einstein condensate in one-dimension. For weak repuls…
Time-Resolved Observation of Spin-Charge Deconfinement in Fermionic Hubbard Chains
Jayadev Vijayan, Pimonpan Sompet, Guillaume Salomon +6
Elementary particles such as the electron carry several quantum numbers, for example, charge and spin. However, in an ensemble of strongly interacting particles, the emerging degre…
Topological polarons, quasiparticle invariants and their detection in 1D symmetry-protected phases
Fabian Grusdt, Norman Y. Yao, Eugene Demler
In the presence of symmetries, one-dimensional quantum systems can exhibit topological order, which in many cases can be characterized by a quantized value of the many-body geometr…
Microscopic spinon-chargon theory of magnetic polarons in the t-J model
Fabian Grusdt, Annabelle Bohrdt, Eugene Demler
The interplay of spin and charge degrees of freedom, introduced by doping mobile holes into a Mott insulator with strong anti-ferromagnetic (AFM) correlations, is at the heart of s…
Floquet approach to lattice gauge theories with ultracold atoms in optical lattices
Christian Schweizer, Fabian Grusdt, Moritz Berngruber +5
Quantum simulation has the potential to investigate gauge theories in strongly-interacting regimes, which are up to now inaccessible through conventional numerical techniques. Here…
