Scaling of the gap, fidelity susceptibility, and Bloch oscillations across the superfluid-to-Mott-insulator transition in the one-dimensional Bose-Hubbard model
We investigate the interaction-induced superfluid-to-Mott-insulator transition in the one-
dimensional Bose-Hubbard model (BHM) for fillings n= 1, n= 2, and n= 3 by studying the …

Symmetry Protection of Critical Phases and a Global Anomaly in Dimensions
SC Furuya, M Oshikawa - Physical review letters, 2017 - APS
We derive a selection rule among the (1+ 1)-dimensional SU (2) Wess-Zumino-Witten
theories, based on the global anomaly of the discrete Z 2 symmetry found by Gepner and …
