Chiral Gauge Theory for Graphene

Gauge Theory of Chiral

Indirect CP violation is analyzed in the framework of the electroweak gauge theory of J = 0 mesons proposed in [1] in which they transform like composite fermion-antifermion operators by the chiral U (N) L × U (N) R group and by the SU (2) L × U (1) gauge group of the Glashow-Salam-Weinberg model [2]. It is shown that, in this model where, in particular, mass terms are introduced for the mesons...

Regulated Chiral Gauge Theory

After a brief introduction to the overlap two examples relating to topological properties of chiral fermion systems in interaction with gauge fields are presented: It is shown how the overlap preserves the continuum structure of exact fermionic zero modes in gauge backgrounds that are instanton-like and why chiral anomalies are inevitable.

We construct a chiral gauge theory to describe fractionalization of fermions in graphene. Thereby we extend a recently proposed model, which relies on vortex formation. Our chiral gauge fields provide dynamics for the vortices and also couple to the fermions.

Gauge Freedom in Chiral Gauge Theory with Vacuum Overlap

In the vacuum overlap formalism[1] of a generic chiral gauge theory, gauge symmetry is explicitly broken by the complex phase of fermion determinant. In order to restore the gauge invariance, gauge average—the integration along gauge orbit— is invoked. Then, what is required for the dynamical nature of the gauge freedom at β = ∞ (pure gauge limit) is that the global gauge symmetry is not broken...
