Change of θ dependence in 4D SU(N) gauge theories across the deconfinement transition
(2013)We study the dependence of 4D SU(N) gauge theories on the topological θ term at finite temperature T. We exploit the lattice formulation of the theory, presenting numerical results for the expansion of the free energy up ...

Eight-Dimensional Quantum Hall Effect and "Octonions"
(2003)A generalization of the quantum Hall effect (QHE) where particles move in an eight-dimensional space under an SO(8) gauge field was constructed. A nonrelativistic Hamiltonian for particles moving on the S8 in the presence ...

Novel nonlocal gauge functions in electrodynamics and their effect on quantum mechanical phases
(2011)We point to previously overlooked solutions of the standard gauge transformation equations of Electrodynamics: the generalized "gauge functions" go beyond the usual Dirac phase factors (spatial or temporal integrals of ...

Simulating a CP-violating topological term in gauge theories
(2012)We present recent results on the θ-dependence of four-dimensional SU(N) gauge theories, where θ is the coefficient of the CP-violating topological term in the Lagrangian. In particular, we study the scaling behavior of ...

SU(N) gauge theories in the presence of a topological term
(2008)We review recent results on the θ dependence of the ground-state energy and spectrum of four-dimensional SU(N) gauge theories, where θ is the coefficient of the CP-violating topological term F F in the Lagrangian. In ...

Two-loop renormalization of fermion bilinears on the lattice
(2009)We compute the renormalization functions on the lattice, in the RI′ scheme, of local bilinear quark operators ψ̄ Γψ, where Γ = Î, γ5, γμ, γ5, γμ, γ5 σμν. This calculation is carried out to two loops for the first time. We ...

θ Dependence of 4D SU(N) gauge theories at finite temperature
(Proceedings of Science (PoS), 2013)We report a study of the dependence of 4D SU(N) gauge theories on the topological θ term at finite temperature, and in particular in the large-N limit. We show that theθ dependence drastically changes across the deconfinement ...
