Quantum impurities in finite-temperature Bose gases: Detecting vortex proliferation across the BKT and BEC transitions
Paolo Comaron, Nathan Goldman, Atac Imamoglu +1
Detecting vortices in neutral superfluids represents an outstanding experimental challenge. Using stochastic classical-field methods, we theoretically show that a quantum impurity…
Fate of chiral order and impurity self-pinning in flat bands with local symmetry
Maxime Burgher, Marco Di Liberto, Nathan Goldman +1
Interacting bosons on a single plaquette threaded by a -flux can spontaneously break time-reversal symmetry, resulting in a chiral loop current. Connecting such bosonic -flux…
Floquet dynamical chiral spin liquid at finite frequency
Didier Poilblanc, Matthieu Mambrini, Nathan Goldman
Chiral Spin Liquids (CSL) are quantum spin analogs of electronic Fractional Chern Insulators. Their realizations on ultracold-atom or Rydberg-atom platforms remain very challenging…
Polaron formation in insulators and the key role of hole scattering processes: Band insulators, charge density waves and Mott transition
Ivan Amelio, Giacomo Mazza, Nathan Goldman
A mobile impurity immersed in a non-interacting Fermi sea is dressed by the gapless particle-hole excitations of the fermionic medium. This conventional Fermi-polaron setting is we…
Chiral polaron formation on the edge of topological quantum matter
Amit Vashisht, Ivan Amelio, Laurens Vanderstraeten +3
Immersing a mobile impurity in a quantum many-body environment can reveal fundamental properties of the background medium, hence providing a powerful probe of quantum matter. This…
