Scanning transmission electron microscopy (STEM) has emerged as a uniquely powerful
tool for structural and functional imaging of materials on the atomic level. Driven by …

The exactly solvable Kitaev model on the honeycomb lattice has recently received
enormous attention linked to the hope of achieving novel spin-liquid states with …

In this work, we exhaust all the spin space symmetries, which fully characterize collinear,
noncollinear, and commensurate spiral as well as incommensurate spiral magnetism, etc …

A Majorana fermion is a fermionic particle that is its own antiparticle. Since the theoretical
discovery by Ettore Majorana in 1937, the exotic particle has long been searched in particle …

Quantum spin liquids are an exciting playground for exotic physical phenomena and
emergent many-body quantum states. The realization and discovery of quantum spin liquid …

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 recent emergence of 2D van der Waals magnets down to atomic-layer thickness
provides an exciting platform for exploring quantum magnetism and spintronics applications …

The coexistence of correlated electron and hole crystals enables the realization of quantum
excitonic states, capable of hosting counterflow superfluidity and topological orders with …

Two-dimensional (2D) materials exhibit a wide range of atomic structures, compositions, and
associated versatility of properties. Furthermore, for a given composition, a variety of …

The Kitaev spin liquid provides a rare example of well-established quantum spin liquids in
more than one dimension. It is obtained as the exact ground state of the Kitaev spin model …
