Action at a distance as a full-value solution of Maxwell equations: The basis and application of the separated-potentials method

Chubykalo, Andrew; Smirnov Rueda, Roman (American Physical Society, 1996-05)

The inadequacy of Lie´nard-Wiechert potentials is demonstrated as one of the examples related to the inconsistency of the conventional classical electrodynamics. The insufficiency of the Faraday-Maxwell concept to describe ...
Reply to ‘‘Comment on ‘Action at a distance as a full-value solution of Maxwell equations: The basis and application of the separated-potentials method’ ’’

Chubykalo, Andrew; Smirnov Rueda, Roman (American Physical Society, 1998-03)

The preceding Comment criticized the necessity of introducing an electrodynamics dualism concept based on a novel complete solution of Maxwell’s equations proposed in our previous paper @Phys. Rev. E 53, 5373 ~1996!#. ...
Is the free electromagnetic field a consequence of Maxwell´s equations or a postulate?

Chubykalo, Andrew; Smirnov Rueda, Roman; Munera, Héctor (Springer, 1998-12)

It is generally accepted that solutions of so called "free" Maxwell equations for Q = 0 (null charge density at every point of the whole space) describe a free electromagnetic field for which flux lines neither begin ...
Necessity of simultaneous co-existence of instantaneous and retarded interactions in classical electrodynamics

Chubykalo, Andrew; Jelev Vlaev, Stoyan (International Journal of Modern Physics A, 1999-09-01)

We consider the electromagnetic field of a charge moving with a constant acceleration along an axis. We find that this field obtained from the Li´enard–Wiechert potentials does not satisfy Maxwell equations if one considers ...
Unusual formations of the free electromagnetic field in vacuum

It is shown that there are exact solutions of the free Maxwell equations (FME) in vacuum allowing the existence of stable spherical formations of the free magnetic field and ring-like formations of the free electric ...
Steady-state sphere-like and ring-like formations of the free electromagnetic field in vacuum

Espinoza, Augusto; Chubykalo, Andrew (Sociedad italiana de Física, 2002-12-15)

It is shown that there are exact solutions of the free Maxwell equations in vacuum allowing and existence of closed spherical magnetic surfaces (without electric field on this surface and where magnetic field is tangential ...
Thomas–Fermi–Dirac theory of the hole gas of a double p-type d-doped GaAs quantum wells

Rodríguez Vargas, Isaac; Gaggero Sager, Luís Manuel; Velasco, Víctor (Elsevier, 2003-07)

We present the hole subband structure of two coupled p-type d-doped GaAs quantum wells as a function of the impurity concentration and the distance l between them, including exchange effects. We present an analytical ...
An alternative way of calculating the superlattice Green function for discrete media

Vlaev, Stoyan; Rodríguez Vargas, Isaac; Gaggero Sager, Luís Manuel; Velasco, Víctor (Elsevier, 2004-04)

We present an alternative and efficient way for calculating the superlattice Green function for discrete systems. Theidea is to consider the superlattices as a crystal with the unit cell having the size of the superlattice ...
Experimental test of the compatibility of the definitions of the electromagnetic energy density and the Poynting vector

Chubykalo, Andrew; Espinoza, Augusto; Ivanov, Rumen (Societ`a Italiana di Fisica, 2004-10)

It is shown that the generally accepted definition of the Poynting vector and the energy flux vector defined by means of the energy density of the electromagnetic field (Umov vector) lead to the prediction of the different ...
Subband structure comparison between n- and p-type double delta-doped GaAs quantum wells

Rodríguez Vargas, Isaac; Gaggero Sager, Luís Manuel (Sociedad Mexicana de Física, A.C., 2004-12)

Calculamos la estructura de niveles electrónicos (tipo-n), as´ı como la de huecos (tipo-p) de pozos cuánticos ±-dopados dobles (DDD) en GaAs. Se han tomando en cuenta los efectos de intercambio en el estudio. Las aproximaciones ...

Rodríguez Vargas, Isaac; Gaggero Sager, Luís Manuel; Martínez Orozco, Juan Carlos (Wiley, 2005-02)

We present the hole sub-band structure study in two p-type δ-doped ZnSe QW’s. An analytical expression for the Hartree–Fock potential is obtained following the lines of the Thomas–Fermi–Dirac (TFD) approximation. We have ...
Helmholtz theorem and the V-Gauge in the problem of superluminal and instantaneous signals in classical electrodynamics

Chubykalo, Andrew; Espinoza, Augusto; Alvarado Flores, Rolando; Gutiérrez Rodríguez, Alejandro (Foundations of Physics Letters, 2006-02)

In this work we substantiate the applying of the Helmholtz vector decomposition theorem (H-theorem) to vector fields in classical electrodynamics. Using the H-theorem, within the framework of the twoparameter Lorentz-like ...
Subband and transport calculations in double -type -doped quantum wells in Si

Rodríguez Vargas, Isaac; Gaggero Sager, Luís Manuel (American Institute of Physics, 2006-02)

The Thomas-Fermi approximation is implemented in two coupled n-type -doped quantum wells in Si. An analytical expression for the Hartree-Fock potential is obtained in order to compute the subband level structure. The ...

Experimental test on the applicability of the standard retardation condition to bound magnetic fields

Kholmetskii, Alexander; Missevitch, Oleg; Smirnov Rueda, Roman; Ivanov, Rumen; Chubykalo, Andrew (American Institute of Physics, 2007-01-31)

We start with the fact that the actual consensus on the empirical verification of the standard retardation condition does not take into account the complex structure of the whole electromagnetic field in the near zone. ...
Hole-level structure of double -doped quantum wells in Si: The influence of the split-off band

Rodríguez Vargas, Isaac; Gaggero Sager, Luís Manuel (Elsevier, 2007-02-15)

Reply to ‘Comment on “Helmholtz Theorem and the V-Gauge in the Problem of Superluminal and Instantaneous Signals in Classical Electrodynamics” by A. Chubykalo et al.’ by J.A. Heras [Found. Phys. Lett. vol. 19(6) p. 579 (2006)]

Chubykalo, Andrew; Espinoza, Augusto; Alvarado Flores, Rolando; Gutiérrez Rodríguez, Alejandro (Springer, 2007-09)

José A. Heras has recently raised interesting criticism [1] regarding the conclusions to our paper [2]. His main point is his assertion that the equations we derived for the solenoidal (Es ) and the irrotational (Ei ) ...
Coulomb interaction does not spread instantaneously

Rumen, Ivanov; Andrew, Chubykalo; Rivera Juárez, Juan M. (Cornell University, 2008-02-09)

The experiment is described which shows that Coulomb interaction spreads with a limit velocity and thus this kind of interaction cannot be considered as so called “instantaneous action at a distance”
