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.…
Quantum Hall effect in graphene: A functional determinant approach
C. G. Beneventano, E. M. Santangelo
We start the paper with a brief presentation of the main characteristics of graphene, and of the Dirac theory of massless fermions in 2+1 dimensions obtained as the associated low-…
