This article reviews experimental and theoretical work on Bose-Einstein condensation in
quantum magnets. These magnets are natural realizations of gases of interacting bosons …

Motivated by experiments on Josephson junction arrays in a magnetic field and ultracold
interacting atoms in an optical lattice in the presence of a “synthetic” orbital magnetic field …

We describe a quantum circuit that produces a highly entangled state of N qubits from which
one can efficiently compute expectation values of local observables. This construction yields …

Paramagnetic spin systems with spontaneously broken spatial symmetries, such as valence
bond solid phases, can host topological defects carrying nontrivial quantum numbers, which …

The global coupling of few-level quantum systems (“spins”) to a discrete set of bosonic
modes is a key ingredient for many applications in quantum science, including large-scale …

We propose an unconventional topological quantum phase transition connecting a higher-
order topological insulator (HOTI) and a featureless Mott insulator sharing the same …

Motivated by multiple possible physical realizations, we study the SU (4) quantum
antiferromagnet with a fundamental representation on each site of the triangular lattice. We …

The theory of quantum phase transitions separating different phases with distinct symmetry
patterns at zero temperature is one of the foundations of modern quantum many-body …
