On Enriching the Levin-Wen model with Symmetry
Liang Chang, Meng Cheng, Shawn X. Cui +6
Symmetry protected and symmetry enriched topological phases of matter are of great interest in condensed matter physics due to new materials such as topological insulators. The Lev…
Symmetry Fractionalization, Defects, and Gauging of Topological Phases
Maissam Barkeshli, Parsa Bonderson, Meng Cheng +1
We examine the interplay of symmetry and topological order in dimensional topological phases of matter. We present a definition of the \it topological symmetry \rm group, whi…
Probing Majorana Physics in Quantum Dot Shot Noise Experiments
Dong E. Liu, Meng Cheng, Roman M. Lutchyn
We consider a quantum dot coupled to a topological superconductor and two normal leads and study transport properties of the system. Using Keldysh path-integral approach, we study…
Criticality in Translation-Invariant Parafermion Chains
Wei Li, Shuo Yang, Hong-Hao Tu +1
In this work we numerically study critical phases in translation-invariant parafermion chains with both nearest- and next-nearest-neighbor hopping terms. The model c…
Bridging Fermionic and Bosonic Short Range Entangled States
Yi-Zhuang You, Zhen Bi, Alex Rasmussen +2
In this paper we construct bosonic short range entangled (SRE) states in all spatial dimensions by coupling a gauge field to fermionic SRE states with the same symmetries, an…
Helical order in one-dimensional magnetic atom chains and possible emergence of Majorana bound states
Younghyun Kim, Meng Cheng, Bela Bauer +2
We theoretically obtain the phase diagram of localized magnetic impurity spins arranged in a one-dimensional chain on top of a one- or two-dimensional electron gas with Rashba spin…
