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…
First order Quantum Hall to Wigner crystal phase transition on a triangular lattice: an iDMRG study
Gleb Fedorovich, Clemens Kuhlenkamp, Atac Imamoglu +1
In this work we study a system of interacting fermions on a triangular lattice in the presence of an external magnetic field. We neglect spin and fix a density of one third, with o…
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…
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…
Fermionization and collective excitations of 1D polariton lattices
Johannes Knörzer, Rafał Ołdziejewski, Puneet A. Murthy +1
We theoretically demonstrate that the hallmarks of correlation and fermionization in a one-dimensional exciton-polaritons gas can be observed with state-of-the-art technology. Our…
