Quantum spin liquids form a novel class of matter where, despite the existence of strong
exchange interactions, spins do not order down to the lowest measured temperature …

Magnetic insulators have proved to be fertile ground for studying new types of quantum
many-body state, and I survey recent experimental and theoretical examples. The insights …

The defining problem in frustrated quantum magnetism, the ground state of the nearest-
neighbor S= 1/2 antiferromagnetic Heisenberg model on the kagome lattice, has defied all …

We perform a density-matrix renormalization group (DMRG) study of the S= 1 2 Heisenberg
antiferromagnet on the kagome lattice to identify the conjectured spin liquid ground state …

The electronic orders in Hubbard models on a kagome lattice at van Hove filling are of
intense current interest and debate. We study this issue using the singular-mode functional …

Quantum spin liquid (QSL) is a novel state of matter which refuses the conventional spin
freezing even at 0 K. Experimentally searching for the structurally perfect candidates is a big …

Muon spin relaxation (μ SR) experiments on single crystals of the structurally perfect
triangular antiferromagnet YbMgGaO 4 indicate the absence of both static long-range …

We apply moderate-high-energy inelastic neutron scattering (INS) measurements to
investigate Yb 3+ crystalline electric field (CEF) levels in the triangular spin-liquid candidate …

We study the energy and the static spin structure factor of the ground state of the spin-1/2
quantum Heisenberg antiferromagnetic model on the kagome lattice. By the iterative …

Topological phases in frustrated quantum spin systems have fascinated researchers for
decades. One of the earliest proposals for such a phase was the chiral spin liquid, a bosonic …
