Light pseudoscalar meson masses under strong magnetic fields within the SU(3) Nambu-Jona-Lasinio model
(American Physical Society, 2021-11)
We calculate the pole masses of pseudoscalar mesons in a strongly magnetized medium within the framework of the SU(3) Nambu-Jona-Lasinio model, using a magnetic field-independent regularization scheme. We employ both a ...
Long-term changes in solar quiet (Sq) geomagnetic variations related to Earth?s magnetic field secular variation
(American Geophysical Union, 2013-01)
The daily amplitude of the solar quiet (Sq) magnetic variation of the horizontal intensity, H, of observatories at low and midlatitudes is analyzed, in search of significant long‐term trends. These trends are expected based ...

Modelling electromagnetic responses of 2-D structures due to spatially non-uniform inducing fields. Analysis of magnetotelluric source effects at coastlines
(Wiley Blackwell Publishing, Inc, 2003-10)
In previous works, we presented 2-D and 3-D magnetotelluric modelling methods based on Rayleigh-Fourier expansions. These methods are an alternative to finite-element and finite-difference techniques and are especially ...
Magnetic contributions in Bekenstein type models
(American Physical Society, 2018-02)
In this work, we analyze the spatial and time variation of the fine structure constant (α) upon the theoretical framework developed by Bekenstein (Phys. Rev. D 66, 123514 (2002)PRVDAQ0556-282110.1103/PhysRevD.66.123514). ...
Critical Theory of Two-Dimensional Mott Transition: Integrability and Hilbert Space Mapping
(Scientific Research Publishing, 2015-04)
We reconsider the Mott transition in the context of a two-dimensional fermion model with density-density coupling. We exhibit a Hilbert space mapping between the original model and the Double Lattice Chern-Simons theory ...
Optimum Integration Procedure for Connectionist and Dynamic Field Equations
(Frontiers Media, 2021-05)
Connectionist and dynamic field models consist of a set of coupled first-order differential equations describing the evolution in time of different units. We compare three numerical methods for the integration of these ...
Initializing a mesoscale boundary layer model with radiosonde observations
(Springer, 2017-08)
A mesoscale boundary-layer model is used to simulate low-level regional wind fields over the La Plata River of South America, a region characterized by a strong daily cycle of land–river surface-temperature contrast and ...
Correlation entropy of an interacting quantum field and H theorem for the [Formula Presented] model
(American Physical Society, 2003-12)
Following the Boltzmann-BBGKY paradigm we propose a correlation entropy (of the nth order) for an interacting quantum field. The concept of correlation entropy is useful for addressing issues related to thermalization. As ...
Magnetic domain wall creep and depinning: A scalar field model approach
(American Physical Society, 2018-06-11)
Magnetic domain wall motion is at the heart of new magnetoelectronic technologies and hence the need for a deeper understanding of domain wall dynamics in magnetic systems. In this context, numerical simulations using ...
