Chiral Mott insulators, Meissner effect, and Laughlin states in quantum ladders
A Petrescu, K Le Hur - Physical Review B, 2015 - APS
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 …

Construction of bosonic symmetry-protected-trivial states and their topological invariants via nonlinear models
XG Wen - Physical Review B, 2015 - APS
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 …

Multikink topological terms and charge-binding domain-wall condensation induced symmetry-protected topological states: Beyond chern-simons/bf field theories
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 …
