Theta Subgroup Structure of Maxwell theory in the Lattice Villain Hamiltonian Formulation
Shoto Aoki, Yoshio Kikukawa, Toshinari Takemoto
We study the duality structure of lattice Maxwell theory with a theta term in the Hamiltonian Villain formulation. Reflecting the fact that odd-level Chern--Simons theory depends o…

Exact SL(2,Z)-Structure of Lattice Maxwell Theory with -term in Modified Villain Formulation
Shoto Aoki, Yoshio Kikukawa, Toshinari Takemoto
We study the duality of lattice Maxwell theory in the modified Villain formulation, employing an ultra-local action with a theta term. Although this action is known to become non u…

Chiral Anomaly of Kogut-Susskind Fermion in the (3+1)-dimensional Hamiltonian formalism
Shoto Aoki, Yoshio Kikukawa, Toshinari Takemoto
We consider Kogut-Susskind fermions (also known as staggered fermions) in a -dimensional Hamiltonian formalism and examine a chiral transformation and its associated chiral…
