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…
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…
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…
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…
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…
