Recursive renormalization of the singlet one-pion-exchange plus point-like interactions
(Elsevier Science BvAmsterdamHolanda, 2005)
Effects on light propagating in an electromagnetized vacuum, as predicted by a particular class of scalar tensor theory of gravitation
(IOP Publishing, 2013-10)
The effect of static electromagnetic fields on the propagation of light is analyzed in the context of a particular class of scalar–tensor gravitational theories. It is found that for appropriate field configurations and ...
Universal scaling in BCS superconductivity in three dimensions in non-s waves
(1998-12-01)
The solutions of a renormalized BCS equation are studied in three space dimensions in s, p and d waves for finite-range separable potentials in the weak to medium coupling region. In the weak-coupling limit, the present ...
Inflationary perturbations in anisotropic, shear-free universes
(2012)
In this work, the linear and gauge-invariant theory of cosmological perturbations in a class of anisotropic and shear-free spacetimes is developed. After constructing an explicit set of complete eigenfunctions in terms of ...
3-loop gauge coupling for hot gauge theories
(2018)
This talk offers a brief review of the determination of coupling constants in the framework of dimensionally reduced effective field theories for thermal QCD, specializing on its gluonic sector. Interestingly, higher-order ...
Yang-Mills action from open superstring field theory
(2003-09-01)
We calculate the effective action for nonabelian gauge bosons up to quartic order using WZW-like open superstring field theory. After including level zero and level one contributions, we obtain with 75% accuracy the ...

Seeking a fingerprint: analysis of point processes in actigraphy recording
(IOP Publishing, 2016-05)
Motor activity of humans displays complex temporal fluctuations which can be characterised by scale-invariant statistics, thus demonstrating that structure and fluctuations of such kinetics remain similar over a broad range ...
