Supersolid, an exotic quantum state of matter that consists of particles forming an
incompressible solid structure while simultaneously showing superfluidity of zero viscosity …

Abstract Antiferromagnetically coupled S= 1/2 spins on an isotropic triangular lattice are the
paradigm of frustrated quantum magnetism, but structurally ideal realizations are rare. Here …

High-quality single crystals of NaYbSe 2, which resembles a perfect triangular-lattice
antiferromagnet without intrinsic disorder, are investigated by magnetization and specific …

Accurate simulations of the two-dimensional (2D) Hubbard model constitute one of the most
challenging problems in condensed matter and quantum physics. Here we develop a …

Quantum spin liquids (QSLs) are theoretical states of matter with long-range entanglement
and exotic quasiparticles. However, they generally elude quantitative theory, rendering their …

We report heat capacity measurements of SrCu 2 (BO 3) 2 under high pressure along with
simulations of relevant quantum spin models and map out the (P, T) phase diagram of the …

Frustrated magnets hold the promise of material realizations of exotic phases of quantum
matter, but direct comparisons of unbiased model calculations with experimental …

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 …

Understanding the nature of the excitation spectrum in quantum spin liquids is of
fundamental importance, in particular for the experimental detection of candidate materials …

The physics of the triangular lattice Hubbard model exhibits a rich phenomenology, ranging
