Bosonic topological phases of matter: bulk-boundary correspondence, SPT invariants and gauging
Apoorv Tiwari, Xiao Chen, Ken Shiozaki +1
We analyze and Bosonic Symmetry Protected Topological (SPT) phases of matter protected by onsite symmetry group by using dual bulk and boundary approaches. In the…
Entanglement entropy of (3+1)D topological orders with excitations
Xueda Wen, Huan He, Apoorv Tiwari +2
Excitations in (3+1)D topologically ordered phases have very rich structures. (3+1)D topological phases support both point-like and string-like excitations, and in particular the l…
Log-rise of the Resistivity in the Holographic Kondo Model
Bikash Padhi, Apoorv Tiwari, Chandan Setty +1
We study a single-channel Kondo effect using a recently developed holographic large- technique. In order to obtain resistivity of this model, we introduce a probe field. The gra…
Gauging (3+1)-dimensional topological phases: an approach from surface theories
Xiao Chen, Apoorv Tiwari, Chetan Nayak +1
We discuss several bosonic topological phases in (3+1) dimensions enriched by a global symmetry, and gauging the symmetry. More specifically, followin…
Boundary conformal field theory and symmetry protected topological phases in dimensions
Bo Han, Apoorv Tiwari, Chang-Tse Hsieh +1
We propose a diagnostic tool for detecting non-trivial symmetry protected topological (SPT) phases protected by a symmetry group in 2+1 dimensions. Our method is based on direc…
