Chiral magnetic effect at finite temperature in a field-theoretic approach
C. G. Beneventano, M. Nieto, E. M. Santangelo
We investigate the existence (or lack thereof) of the chiral magnetic effect in the framework of finite temperature field theory, studied through the path integral approach and reg…
To gap or not to gap? Mass distortions and edge modes in graphene armchair nanoribbons
C. G. Beneventano, I. V. Fialkovsky, M. Nieto +1
We investigate, in the framework of macroscopic Dirac model, the spectrum, charge density and conductivity of metallic armchair graphene nanoribbons in presence of different mass t…
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…
Zeroes of combinations of Bessel functions and mean charge of graphene nanodots
C. G. Beneventano, I. V. Fialkovsky, E. M. Santangelo
We establish some properties of the zeroes of sums and differences of contiguous Bessel functions of the first kind. As a byproduct, we also prove that the zeroes of the derivative…
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…
Charge density and conductivity of disordered Berry-Mondragon graphene nanoribbons
C. G. Beneventano, I. V. Fialkovsky, E. M. Santangelo +1
We consider gated graphene nanoribbons subject to Berry-Mondragon boundary conditions in the presence of weak impurities. Using field--theoretical methods, we calculate the density…
