Frustration in magnetic materials arising from competing exchange interactions can prevent
the system from adopting long-range magnetic order and can instead lead to a diverse …

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 …

Quantum circuit dynamics with local projective measurements can realize a rich spectrum of
entangled states of quantum matter. Motivated by the physics of the Kitaev quantum spin …

Quantum fluctuations can inhibit long-range ordering in frustrated magnets and potentially
lead to quantum spin liquid (QSL) phases. A prime example are gapless QSLs with …

The Kitaev honeycomb model has attracted significant attention due to its exactly solvable
spin-liquid ground state with fractionalized Majorana excitations and its possible …

The excitations in the Kitaev spin liquid (KSL) can be described by Majorana fermions,
which have characteristic field dependence of bulk gap and topological edge modes. In the …

Kitaev magnets are materials with bond-dependent Ising interactions between localized
spins on a honeycomb lattice. Such interactions could lead to a quantum spin-liquid (QSL) …

Topological insulator phases of non-interacting particles have been generalized from
periodic crystals to amorphous lattices, which raises the question whether topologically …
