The discovery of the quantum spin Hall effect and topological insulators more than a decade
ago has revolutionized modern condensed matter physics. Today, the field of topological …

We introduce generic bosonic models exemplifying that chiral Meissner currents can persist
in insulating phases of matter. We first consider interacting bosons on a two-leg ladder. The …

It has been shown that the bosonic symmetry-protected-trivial (SPT) phases with pure gauge
anomalous boundary can all be realized via nonlinear σ models (NL σ Ms) of the symmetry …

We study a bosonic model with correlated hopping on a honeycomb lattice, and show that its
ground state is a bosonic integer quantum Hall (BIQH) phase, a prominent example of a …

The boundary of symmetry-protected topological states (SPTs) can harbor new quantum
anomaly phenomena. In this work, we characterize the bosonic anomalies introduced by the …

Bosonic topological insulators (BTIs) in three dimensions are symmetry-protected
topological phases protected by time-reversal and boson number conservation symmetries …

Symmetry-protected topological phases (SPT) are short-range entangled gapped states
protected by global symmetry. Nontrivial SPT phases cannot be adiabatically connected to …

Recent experiments in ultracold atoms and photonic analogs have reported the
implementation of artificial gauge fields in lattice systems, facilitating the realization of …

Symmetry-protected topological (SPT) phases of matter have been the focus of many recent
theoretical investigations, but controlled mechanisms for engineering them have so far been …

Quantum disordering a discrete-symmetry-breaking state by condensing domain walls can
lead to a trivial symmetric insulator state. In this work, we show that if we bind a one …
