Polarons—electronic charge carriers ‘dressed’ by a local polarization of the background environment—are among the most fundamental quasiparticles in interacting many-body systems, and emerge even at the level of a single dopant1. In the context of the two-dimensional Fermi–Hubbard model, polarons are predicted to form around charged dopants in an antiferromagnetic background in the low-doping regime, close to the Mott insulating state2–7; this prediction is supported by macroscopic transport… 
Unbiased description of magnetic polarons in a Mott insulator
Polarons are among the most elementary quasiparticles of interacting quantum matter, consisting of a charge carrier dressed by an excited background. In Mott insulators, they take the form of a
Dynamical interplay between a single hole and a Hubbard antiferromagnet
In strongly correlated quantum materials, the intricate interplay between charge carriers and spins leads to a breakdown of the conventional notion of charge transport. A prime example of such
Microscopic spinon-chargon theory of magnetic polarons in the t−J model
The interplay of spin and charge degrees of freedom, introduced by doping mobile holes into a Mott insulator with strong antiferromagnetic (AFM) correlations, is at the heart of strongly correlated
Repulsive Fermi and Bose Polarons in Quantum Gases
Polaron quasiparticles are formed when a mobile impurity is coupled to the elementary excitations of a many-particle background. In the field of ultracold atoms, the study of the associated impurity
Microscopic evolution of doped Mott insulators from polaronic metal to Fermi liquid
TLDR
A crossover in Fermi-Hubbard systems on a cold-atom quantum simulator is observed and the transformation of multipoint correlations between spins and holes upon increasing doping at temperatures around the superexchange energy is revealed.
Rotational Resonances and Regge-like Trajectories in Lightly Doped Antiferromagnets.
TLDR
A rotational variant of angle-resolved photo-emission spectroscopy (ARPES) is proposed and long-lived rotational resonances for an individual dopant are identified, which are interpreted as a direct indicator of the microscopic structure of spinon-chargon bound states.
Strong pairing in mixed-dimensional bilayer antiferromagnetic Mott insulators
Interacting many-body systems in reduced-dimensional settings, such as ladders and few-layer systems, are characterized by enhanced quantum fluctuations. Recently, two-dimensional bilayer systems
Spin-Mediated Mott Excitons
Motivated by recent experiments on Mott insulators, in both iridates and ultracold atoms, we theoretically study the effects of magnetic order on the Mott-Hubbard excitons. In particular, we focus on
Dynamical formation of a magnetic polaron in a two-dimensional quantum antiferromagnet
We numerically study the real-time dynamics of a single hole created in the $t-J$ model on a square lattice. Initially, the hole spreads ballistically with a velocity proportional to the hopping
Fate of pairing and spin-charge separation in the presence of long-range antiferromagnetism
We present a numerical study of competing orders in the 1D t-J model with long-range RKKY-like staggered spin interactions. By circumventing the constraints imposed by Mermin-Wagner’s theorem, this

TLDR
The results demonstrate that microscopy of cold atoms in optical lattices can help to understand the low-temperature Fermi–Hubbard model and provide a valuable benchmark for numerical simulations.
Direct observation of incommensurate magnetism in Hubbard chains
TLDR
Direct observation of incommensurate spin correlations in doped and spin-imbalanced Hubbard chains confirms two fundamental predictions for Luttinger liquids and shows that such correlations are suppressed by interchain coupling.

Parton theory of magnetic polarons: Mesonic resonances and signatures in dynamics
When a mobile hole is moving in an anti-ferromagnet it distorts the surrounding Neel order and forms a magnetic polaron. Such interplay between hole motion and anti-ferromagnetism is believed to be
Bad metallic transport in a cold atom Fermi-Hubbard system
TLDR
This work studies transport in a clean quantum system: ultracold lithium-6 in a two-dimensional optical lattice, a testing ground for strong interaction physics in the Fermi-Hubbard model, and determines the diffusion constant by measuring the relaxation of an imposed density modulation and modeling its decay hydrodynamically.

Quantum dimer model for the pseudogap metal
TLDR
This model describes an exotic metal that is similar in many respects to simple metals like silver, however, the simple metallic character coexists with “topological order” and long-range quantum entanglement previously observed only in exotic insulators or fractional quantum Hall states in very high magnetic fields.
