Stochastic quantization of a self-interacting nonminimal scalar field in semiclassical gravity
(Elsevier B.V., 2019-11-10)
We employ stochastic quantization for a self-interacting nonminimal massive scalar field in curved spacetime. The covariant background field method and local momentum space representation are used to obtain the Euclidean ...
QCD effective charge and the structure function F-2 at small-x
(Elsevier B.V., 2011-03-28)
We study infrared contributions to the QCD description of the HERA data on the structure function F-2 within the generalized DAS approximation. We argue that this approximation is a natural one and consistent with the ...
Nonperturbative effective-field theory for two-leg antiferromagnetic spin ladders
(American Physical Society, 2001-12)
We study the long wavelength limit of a spin- 2 Heisenberg antiferromagnetic two-leg ladder, treating the interchain coupling in a nonperturbative way. We perform a mean field analysis and then include the fluctuations in ...
Nonperturbative correlation effects in diluted magnetic semiconductors
(American Physical Society, 2016-01)
The effects of carrier-impurity correlations due to a Kondo-like spin-spin interaction in diluted magnetic semiconductors are investigated. These correlations are not only responsible for a transfer of spins between the ...
Higher grading conformal affine Toda theory and (generalized) sine-Gordon/massive Thirring duality
(2003-11-01)
Some properties of the higher grading integrable generalizations of the conformal affine Toda systems are studied. The fields associated to the non-zero grade generators are Dirac spinors. The effective action is written ...

QCD fixed points: Banks-Zaks scenario or dynamical gluon mass generation?
(2017-01-30)
Fixed points in QCD can appear when the number of quark flavors (Nf) is increased above a certain critical value as proposed by Banks and Zaks (BZ). There is also the possibility that QCD possess an effective charge ...
The impact of transverse Slavnov-Taylor identities on dynamical chiral symmetry breaking
(2021-11-01)
We extend earlier studies of transverse Ward-Fradkin-Green-Takahashi identities in QED, their usefulness to constrain the transverse fermion-boson vertex and their importance for multiplicative renormalizability, to the ...
