Aspects of renormalization in finite-density field theory
(American Physical Society, 2015-05-15)
We study the renormalization of the Fermi surface coupled to a massless boson near three spatial dimensions. For this, we set up a Wilsonian RG with independent decimation procedures for bosons and fermions, where the ...
Renormalized coordinate approach to the thermalization process
(2009-03-03)
We consider a particle in the harmonic approximation coupled linearly to an environment modeled by an infinite set of harmonic oscillators. The system (particle environment) is considered in a cavity at thermal equilibrium. ...

On the removal of infinities from divergent series
(University of Exeter. School of Education, 2015-07)
The consequences of adopting other definitions of the concepts of sum and convergence of a series are discussed in the light of historical and epistemological contexts. We show that some divergent series appearing in the ...
Renormalization on noncommutative torus
(Springer, 2016-04)
We study a self-interacting scalar φ4 theory on the d-dimensional noncommutative torus. We determine, for the particular cases d= 2 and d= 4 , the counterterms required by one-loop renormalization. We discuss higher loops ...
Renormalized coordinate approach to the thermalization process
(Amer Physical Soc, 2009-03-01)
We consider a particle in the harmonic approximation coupled linearly to an environment modeled by an infinite set of harmonic oscillators. The system (particle environment) is considered in a cavity at thermal equilibrium. ...
Nucleon-nucleon scattering within a multiple subtractive renormalization approach
(2011-06-15)
We present a methodology to renormalize the nucleon-nucleon interaction in momentum space, using a recursive multiple subtraction approach that prescinds from a cutoff regularization, to construct the kernel of the scattering ...
