DOI: 10.1007/jhep07(2019)062
Abstract: A bstractWe discuss the low-energy dynamics of superfluidity with topological order in (3 + 1) spacetime dimensions. We generalize a topological BF theory by introducing a non-square K matrix, and this generalized BF theory can… read more here.

DOI: 10.1038/s41586-020-2318-5
Abstract: Much of the richness in nature emerges because simple constituents form an endless variety of ordered states 1 . Whereas many such states are fully characterized by symmetries 2 , interacting quantum systems can exhibit… read more here.

DOI: 10.1103/physreva.95.032324
Abstract: We examine two proposals for marginally-self-correcting quantum memory: the cubic code by Haah and the welded code by Michnicki. In particular, we prove explicitly that they are absent of topological order above zero temperature, as… read more here.

DOI: 10.1103/physreva.95.042330
Abstract: Topological order is now being established as a central criterion for characterizing and classifying ground states of condensed matter systems and complements categorizations based on symmetries. Fractional quantum Hall systems and quantum spin liquids are… read more here.

DOI: 10.1103/physrevb.104.245113
Abstract: We propose here a counterdiabatic (CD) strategy for fast preparation of a state with long-range topological order by magnetic field tuning of an initial separable state. For concreteness, we consider the ground state of the… read more here.

DOI: 10.1103/physrevb.95.235107
Abstract: We apply symmetric tensor network state (TNS) to study the nearest neighbor spin-1/2 antiferromagnetic Heisenberg model on Kagome lattice. Our method keeps track of the global and gauge symmetries in TNS update procedure and in… read more here.

DOI: 10.1103/physrevb.95.235140
Abstract: Gapped quantum liquids (GQL) include both topologically ordered states (with long range entanglement) and symmetry protected topological (SPT) states (with short range entanglement). In this paper, we propose a classification of 2+1D GQL for both… read more here.

DOI: 10.1103/physrevlett.128.056401
Abstract: Electronic properties of crystals are inherently pertained to crystalline symmetry, so that amorphization that lowers and breaks symmetry is detrimental. One important crystalline property is electron band topology which is known to be weakened and… read more here.
