Spin liquids are collective phases of quantum matter that have eluded discovery in
correlated magnetic materials for over half a century. Theoretical models of these enigmatic …

Having served as a playground for fundamental studies on the physics of d and f electrons
for almost a century, magnetic molecules are now becoming increasingly important for …

In recent years inelastic spin-flip spectroscopy using a low-temperature scanning tunneling
microscope has been a very successful tool for studying not only individual spins but also …

We demonstrate theoretically that the thermal Hall effect of magnons in collinear
antiferromagnetic insulators is an indicator of magnetic and topological phase transitions in …

The ability to manipulate single atoms has opened up the door to constructing interesting
and useful quantum structures from the ground up. On the one hand, nanoscale …

Direct measurements of spin fluctuations are becoming the mainstream approach for studies
of complex condensed matter, molecular, nuclear, and atomic systems. This review covers …

The bulk-boundary correspondence is a defining feature of topological states of matter.
However, for quantum magnets in two dimensions such as spin liquids or topological …

Spin-ordered states close to metal-insulator transitions are poorly understood theoretically
and challenging to probe in experiments. Here, we propose that the quantum twisting …

We present a brief pedagogical review of theoretical Green's function methods applicable to
open quantum systems out of equilibrium, in general, and single molecule junctions, in …

A quantum spin liquid with a spinon Fermi surface is an exotic insulator that hosts neutral
Fermi surfaces inside the insulating gap. In an external magnetic field, it has been pointed …
