Quantum spin liquids may be considered'quantum disordered'ground states of spin systems,
in which zero-point fluctuations are so strong that they prevent conventional magnetic long …

Quantum spin liquids have fascinated condensed matter physicists for decades because of
their unusual properties such as spin fractionalization and long-range entanglement. Unlike …

Recently, the effects of spin-orbit coupling (SOC) in correlated materials have become one
of the most actively studied subjects in condensed matter physics, as correlations and SOC …

In transition-metal compounds with partially filled 4 d and 5 d shells spin–orbit
entanglement, electronic correlations, and crystal-field effects conspire to give rise to a …

The emergence of novel quantum ground states in correlated electron systems with strong
spin–orbit coupling has been a recent subject of intensive studies. While it has been …

Recently there have been several proposals of materials predicted to be nodal-ring
semimetals, where zero energy excitations are characterized by a nodal ring in the …

In transition-metal compounds with partially filled $4 d $ and $5 d $ shells spin-orbit
entanglement, electronic correlations, and crystal-field effects conspire to give rise to a …

We study the intrinsic fully gapped odd-parity superconducting order in doped nodal-loop
materials with a torus-shaped Fermi surface. We show that the mirror symmetry, which …

The fractionalization of elementary excitations in quantum spin systems is a central theme in
current condensed matter physics. The Kitaev honeycomb spin model provides a prominent …

Topological properties play an increasingly important role in future research and technology.
This also applies to the field of topological magnetic excitations which has recently become …
