This is an introductory review of the physics of quantum spin liquid states. Quantum
magnetism is a rapidly evolving field, and recent developments reveal that the ground states …

Topological superconductivity can emerge from the combination of conventional
superconductivity in a metal and strong spin–orbit coupling in a semiconductor when they …

Quantum-enhanced measurements exploit quantum mechanical effects for increasing the
sensitivity of measurements of certain physical parameters and have great potential for both …

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

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 …

We show that an ordinary semiconducting thin film with spin-orbit coupling can, under
appropriate circumstances, be in a quantum topologically ordered state supporting exotic …

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 …

Topological quantum computation is a computational paradigm based on topological
phases of matter, which are governed by topological quantum field theories. In this …

We study the spin-1 2 Heisenberg model on the triangular lattice with antiferromagnetic first-
(J 1) and second-(J 2) nearest-neighbor interactions using density matrix renormalization …

Topological phases in frustrated quantum spin systems have fascinated researchers for
decades. One of the earliest proposals for such a phase was the chiral spin liquid, a bosonic …
