Pairs Emission in a Uniform Background Field: an Algebraic Approach
Roberto Soldati
A fully algebraic general approach is developed to treat the pairs emission and absorption in the presence of some uniform external background field. In particular, it is shown tha…
The Unruh effect revisited
Pietro Longhi, Roberto Soldati
A new and exact derivation of the Bogoliubov coefficients is obtained for the simplest case of a spinless, neutral, massive field in a uniformly accelerated frame with a constant a…
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.…
The quantum Hall effect in graphene samples and the relativistic Dirac effective action
C. G. Beneventano, Paola Giacconi, E. M. Santangelo +1
We study the Euclidean effective action per unit area and the charge density for a Dirac field in a two--dimensional spatial region, in the presence of a uniform magnetic field per…
Effective action for Dirac spinors in the uniform electromagnetic background fields
Roberto Soldati, Lorenzo Sorbo
Some new expressions are found, concerning the effective action as a regularized path-integral for Dirac's spinors in {\it 3+1} dimensions, in the presence of general uniform (i.e.…
The Mandelstam--Leibbrandt Prescription and the Discretized Light Front Quantization
Roberto Soldati
It is shown that the quantization of the unphysical degrees of freedom, which leads to the Mandelstam--Leibbrandt prescription for the infrared spurious singularities in the contin…
