Strong electronic correlations pose one of the biggest challenges to solid state theory.
Recently developed methods that address this problem by starting with the local, eminently …

Numerous correlated electron systems exhibit a strongly scale-dependent behavior. Upon
lowering the energy scale, collective phenomena, bound states, and new effective degrees …

Motivated by experimental studies that have found signatures of a quantum spin liquid
phase in organic crystals whose structure is well described by the two-dimensional …

The nature of quantum spin liquids, a novel state of matter where strong quantum
fluctuations destroy the long-range magnetic order even at zero temperature, is a long …

Quantum gas microscopes have expanded the capabilities of quantum simulation of
Hubbard models by enabling the study of spatial spin and density correlations in square …

At strong repulsion, the triangular-lattice Hubbard model is described by s= 1/2 spins with
nearest-neighbor antiferromagnetic Heisenberg interactions and exhibits conventional 120° …

Electron correlation and spin frustration are among the central issues in condensed matter
physics, and their interplay is expected to bring about exotic phases with both charge and …

We investigate fermionic Mott insulators in a geometrically frustrated triangular lattice, a
paradigm model system for studying spin liquids and spontaneous time-reversal symmetry …

We study kinetic magnetism for the Fermi-Hubbard model in triangular lattices. We focus on
the regime of strong interactions, U≫ t, and filling factors around one electron per site. For …

The interplay between spin frustration and charge fluctuation gives rise to an exotic quantum
state in the intermediate-interaction regime of the half-filled triangular-lattice Hubbard model …
