Spin quantum Hall effects in a spin-1 topological paramagnet
Yuan-Ming Lu, Dung-Hai Lee
AKLT state (or Haldane phase) in a spin-1 chain represents a large class of gapped topological paramagnets, which hosts symmetry-protected gapless excitations on the boundary. In t…
Quantum phase transitions between bosonic symmetry protected topological phases in two dimensions: emergent and anyon superfluid
Yuan-Ming Lu, Dung-Hai Lee
Inspired by Chern-Simons effective theory description of symmetry protected topological (SPT) phases in two dimensions, we present a projective construction for many-body wavefunct…
Superconductivity of doped Weyl semimetals: finite-momentum pairing and electronic analogues of the 3He-A phase
Gil Young Cho, Jens H. Bardarson, Yuan-Ming Lu +1
We study superconducting states of doped inversion-symmetric Weyl semimetals. Specifically, we consider a lattice model realizing a Weyl semimetal with an inversion symmetry and st…
Gapless edge states of BF field theory and translation-symmetric Z2 spin liquids
Gil Young Cho, Yuan-Ming Lu, Joel E. Moore
We study possible gapless edge states of translation-symmetric Z2 spin liquids. The gapless edge states emerge from dangling Majorana fermions at the boundary. We construct a serie…
Theory and classification of interacting 'integer' topological phases in two dimensions: A Chern-Simons approach
Yuan-Ming Lu, Ashvin Vishwanath
We study topological phases of interacting systems in two spatial dimensions in the absence of topological order (i.e. with a unique ground state on closed manifolds and no fractio…
Majorana fermions in spin-singlet nodal superconductors with coexisting non-collinear magnetic order
Yuan-Ming Lu, Ziqiang Wang
Realizations of Majorana fermions in solid state materials have attracted great interests recently in connection to topological order and quantum information processing. We propose…
