Effective field theories of topological crystalline insulators and topological crystals [PDF]

open access: yesPhysical Review B, 2022
We present a general approach to obtain effective field theories for topological crystalline insulators whose low-energy theories are described by massive Dirac fermions. We show that these phases are characterized by the responses to spatially dependent

Topological Quantum Statistical Mechanics and Topological Quantum Field Theories

open access: yesSymmetry, 2022
The Ising model describes a many-body interacting spin (or particle) system, which can be utilized to imitate the fundamental forces of nature. Although it is the simplest many-body interacting system of spins (or particles) with Z2 symmetry, the ...

POLYMERS AND TOPOLOGICAL FIELD THEORY

Modern Physics Letters B, 1992
We show that the generating function for self-avoiding paths is formally obtainable from a Witten topological field theory, even if the physical quantities for polymers are not the physical quantities in the BRST approach. We argue that in the dense phase the BRST invariance should generally be broken at the quantum level.
