Effective field theories for interacting boundaries of 3d topological crystalline insulators through bosonisation

HIGHLIGHTS

• who: Patricio Salgado-Rebolledo from the SchoolUniversity of have published the research: Effective field theories for interacting boundaries of 3D topological crystalline insulators through bosonisation, in the Journal: Scientific Reports Scientific Reports of 15/06/2020
• what: The authors show that for a particular value of the couplings the fermionic system can be described in the low energy limit by a single fermion field non-minimally coupled to an effective U(1) gauge field. Since this is a standard Thirring model for the authors can linearise the interactions by where e=χ ψ introducing a vector field . . .
