Directly imaging spin polarons in a kinetically frustrated Hubbard system
The emergence of quasiparticles in quantum many-body systems underlies the rich
phenomenology in many strongly interacting materials. In the context of doped Mott …

Observation of Nagaoka polarons in a Fermi–Hubbard quantum simulator
Quantum interference can deeply alter the nature of many-body phases of matter. In the
case of the Hubbard model, Nagaoka proved that introducing a single itinerant charge can …

Itinerant magnetism and magnetic polarons in the triangular lattice Hubbard model
We use density matrix renormalization group to investigate the phase diagram of the Fermi
Hubbard model on a triangular lattice with densities above half-filling, $1\leq n< 2$. We …
