-
(AMER PHYSICAL SOC, 1999)Tunneling problems are characterized by different quantum time scales of motion. In this paper, we identify a tunneling time scale, which is based on a simple variational principle. The method utilizes the stationary e ...
-
(IOP Publishing, 1999)We propose a new analytical method to solve for the nonexactly solvable Schrodinger equation. Successfully, it is applied to a class of spiked harmonic oscillators and truncated Coulomb potentials. The utility of this ...
-
(Springer-Verlag, 2000)A new pseudoperturbative (artificial in nature) methodical proposal [15] is used to solve for Schrodinger equation with a class of phenomenologically useful and methodically challenging anharmonice oscillator potentials ...
-
(Springer, 2001)The energy levels of neutral atoms supported by Yukawa potential, V(r)=-Z exp(-\alpha r)/r, are studied, using both dimensional and dimensionless quantities, via a new analytical methodical proposal (devised to solve for ...

(Inst Physıcs Acad Scı Czech Republıc, 2001)The energy levels of neutral atoms supported by Yukawa potential, V(r)=-Z exp(-\alpha r)/r, are studied, using both dimensional and dimensionless quantities, via a new analytical methodical proposal (devised to solve for ...
-
(Physical Review D, American Physical Society (APS), 2001)A single pulse of null dust and colliding null dust both transform a regular horizon into a spacelike singularity in the space of colliding waves. The local isometry between such space-times and black holes extrapolates ...
-
(Inst Physics Acad Sci Czech Republic, Springer (Online Publishing), 2002)The D -dimensional quasi - exact solutions for the singular even - power anharmonic potential V(q)=aq^2+bq^{-4}+cq^{-6} are reported. We show that whilst Dong and Ma's [5] quasi - exact ground - state solution (in D=2) is ...
-
(IOP Publishing, 2002)For complex potentials V(x) = -(ix)(3) -beta(2)(ix)(-2) - 2betadelta(ix)(1/2) which are PT symmetric, we show that in beta much greater than 1 strong coupling regime the low-lying bound states almost coincide with harmonic ...
-
(INST PHYSICS ACAD SCI CZECH REPUBLIC, Springer (Online Publishing), 2002)Magnetic fingerprints on the spectra of an interacting electron with a negatively charged ion in a parabolic quantum dot (QD), and of two interacting electrons in such a dot, are investigated via a pseudoperturbative ...
-
(INST PHYSICS ACAD SCI CZECH REPUBLIC, Springer (Online Publishing), 2003)The shifted 1/N expansion technique used by El-Said [Phys. Rev. B 61 (2000) 13026], to study the relative Hamiltonian of two interacting electrons confined in a quantum dot, is investigated. El-Said's results from shifted ...
-
(International Journal of Theoretical Physics, Springer, 2003)A scalar field generalization of Xanthopoulos's cylindrically symmetric solutions of the vacuum Einstein equation is obtained. The obtained solution preserves the properties of the Xanthopoulos solution, which are regular ...
-
(General Relativity and Gravitation, 2003)A technique is given to generate coupled scalar field solutions in colliding Einstein - Maxwell (EM) waves. By employing the Bell - Szekeres solution as seed and depending on the chosen scalar field it is possible to ...
-
(Classical and Quantum Gravity, Institute of Physics (IOP) Publishing, 2003)We present an exact solution that describes collision of electromagnetic shock waves coupled with axion plane waves. The axion has a rather special coupling to the cross polarization term of the metric. The initial data ...
-
(IOP Publishing, 2003)The observation that the existence of the amazing reality and discreteness of the spectrum need not necessarily be attributed to the Hermiticity of the Hamiltonian is re-emphasized in the context of the non-Hermitian Dirac ...
-
(INST PHYSICS ACAD SCI CZECH REPUBLIC , Springer(Online publishing), 2004)A relativistic extension of our pseudo-perturbative shifted l-expansion technique is presented to solve for the eigenvalues of Dirac and Klein-Gordon equations. Once more we show the numerical usefulness of its results via ...
-
Nonsingular colliding wave solutions in Einstein-Maxwell-dilaton-axion theory E. Halilsoy and M. Ha (Physical Review D, American Physical Society (APS), 2004)The local isometry between black holes and colliding plane waves is employed to derive new colliding wave solutions in the Einstein-Maxwell-dilaton-axion theory. The technique is applied to the asymptotically nonflat linear ...
-
(Physical Review -Series d-, American Physical Society (APS), 2004)Dirac equation is solved in the near horizon limit geometry of an extreme Kerr black hole. We decouple equations first as usual, into an axial and angular part. The axial equation turns out to be independent of the mass ...
-
(American Institute of Physics, 2005)We extend the application of the techniques developed within the framework of the pseudo-Hermitian quantum mechanics to study a unitary quantum system described by an imaginary PT-symmetric potential v(x) having a continuous ...
-
(Physical Review D,, 2006)We consider colliding wave packets consisting of hybrid mixtures of electromagnetic, gravitational and scalar waves. Irrespective of the scalar field, the electromagnetic wave still reflects from the gravitational wave. ...
