The long fascination that antiferromagnetic materials has exerted on the scientific community
over about a century has been entirely renewed recently with the discovery of several …

We study the spin liquid candidate of the spin-1/2 J 1-J 2 Heisenberg antiferromagnet on the
triangular lattice by means of density matrix renormalization group (DMRG) simulations. By …

Quantum magnets provide the simplest example of strongly interacting quantum matter, yet
they continue to resist a comprehensive understanding above one spatial dimension. We …

The entanglement entropy is a unique probe to reveal universal features of strongly
interacting many-body systems. In two or more dimensions these features are subtle, and …

The interplay of symmetry and topology has been at the forefront of recent progress in
quantum matter. Here, we uncover an unexpected connection between band topology and …

Motivated by very recent experimental observations of the 1/9-magnetization plateaus in
YCu 3 (OH) 6+ x Br 3-x and YCu 3 (OD) 6+ x Br 3-x, our study delves into the magnetic-field …

Pinch point singularities, associated with flat band magnetic excitations, are tell-tale
signatures of Coulomb spin liquids. While their properties in the presence of quantum …

A clear thermal Hall signal (κ xy) was observed in the spin-liquid phase of the S= 1/2
kagome antiferromagnet Ca kapellasite [CaCu 3 (OH) 6 Cl 2· 0.6 H 2 O]. We found that κ xy …

We demonstrate that the single crystal of YCu 3 [OH (D)] 6.5 Br 2.5 (YCOB) is a kagome
Heisenberg antiferromagnet without evident orphan spins (≪ 0.8%). The site mixing …

We investigate the ground-state properties of the spin-1/2 pyrochlore Heisenberg
antiferromagnet using pseudofermion functional renormalization group techniques. The first …
