Observation of Nagaoka Polarons in a Fermi-Hubbard Quantum Simulator
Martin Lebrat, Muqing Xu, Lev Haldar Kendrick +7
Quantum interference can deeply alter the nature of many-body phases of matter. In the paradigmatic case of the Hubbard model, Nagaoka famously proved that introducing a single iti…

Directly imaging spin polarons in a kinetically frustrated Hubbard system
Max L. Prichard, Benjamin M. Spar, Ivan Morera +3
The emergence of quasiparticles in quantum many-body systems underlies the rich phenomenology in many strongly interacting materials. In the context of doped Mott insulators, magne…

Quantum Cherenkov transition of finite momentum Bose polarons
Kushal Seetharam, Yulia Shchadilova, Fabian Grusdt +2
We investigate the behavior of a finite-momentum impurity immersed in a weakly interacting three-dimensional Bose-Einstein condensate (BEC) of ultra-cold atoms, giving a detailed a…
