Dissipation-induced bulk and boundary criticality in the Haldane chain
Zhenjiu Wang, Manuel Weber
We study the Haldane chain coupled to a dissipative ohmic bath. Using large-scale quantum Monte Carlo simulations, we identify a second-order quantum phase transition into an antif…

Edge modes of topological Mott insulators and deconfined quantum critical points
Yuhai Liu, Toshihiro Sato, Disha Hou +3
Topology and anomalies lead to edge modes that can interact with critical bulk fluctuations. To study this setup, pertaining to boundary criticality, we consider a model exhibiting…

Alteration of Topology in Quantum Phase Transitions via Symmetry Enrichment
Gabriel Rein, Marcin Raczkowski, Zhenjiu Wang +2
Topology plays a cardinal role in explaining phases and quantum phase transitions beyond the Landau-Ginzburg-Wilson paradigm. In this study, we formulate a set of models of Dirac f…
