Searching for a -function on the three-dimensional sphere
C. G. Beneventano, I. Cavero-Peláez, D. D'Ascanio +1
We present a detailed analytic study on the three-dimensional sphere of the most popular candidates for -functions, both for Dirac and scalar free massive fields. We discuss to…
Topological Entropy and Renormalization Group flow in 3-dimensional spherical spaces
M. Asorey, C. G. Beneventano, I. Cavero-Peláez +2
We analyze the renormalization group (RG) flow of the temperature independent term of the entropy in the high temperature limit β/a<<1 of a massive field theory in 3-dimensional sp…
Thermodynamics of conformal fields in topologically non-trivial space-time backgrounds
M. Asorey, C. G. Beneventano, D. D'Ascanio +1
We analyze the finite temperature behaviour of massless conformally coupled scalar fields in homogeneous lens spaces . High and low temperature expansions are ex…
Casimir energy for Dirac fields in
C. G. Beneventano, E. M. Santangelo
We study massless Dirac fields in a portion of , where one of the boundaries coincides with the "boundary at infinity" of the Anti-de-Sitter space. We evaluate the vacuum en…
Planar QED at finite temperature and density: Hall conductivity, Berry's phases and minimal conductivity of graphene
C. G. Beneventano, Paola Giacconi, E. M. Santangelo +1
We study 1-loop effects for massless Dirac fields in two spatial dimensions, coupled to homogeneous electromagnetic backgrounds, both at zero and at finite temperature and density.…
Phases of the Dirac determinant, Abelian Chern-Simons terms and Berry's phases in the field theoretic description of graphene
E. M. Santangelo
This talk presents a study of massless relativistic Dirac fields in three Euclidean dimensions, at finite temperature and density, in the presence of a uniform electromagnetic back…
