Dirac reduced radial equations and the problem of additional solutions
Anzor Khelashvili, Teimuraz Nadareishvili
We show that additional solutions must be ignored (in differences of the Schrodinger and Klein-Gordon equations) in the Dirac equation, where usually passed the second order radial…
Singular Behavior of the Laplace Operator in Polar Spherical Coordinates and Some of Its Consequences for the Radial Wave Function at the Origin of Coordinates
Anzor Khelashvili, Teimuraz Nadareishvili
Singular behavior of the Laplace operator in spherical coordinates is investigated. It is shown that in course of transition to the reduced radial wave function in the Schrodinger…
Bound states on the lattice with partially twisted boundary conditions
D. Agadjanov, F. -K. Guo, G. Ríos +1
We propose a method to study the nature of exotic hadrons by determining the wave function renormalization constant from lattice simulations. It is shown that, instead of study…
Model of Generation of Electromagnetic Emission Detected Before Earthquake
M. Kachakhidze, N. Kachakhidze, T. Kaladze
The paper offers physical bases of earth EM emission in the earthquake preparation period.
A framework for the calculation of the transition form factors on the lattice
Andria Agadjanov, Véronique Bernard, Ulf-G. Meißner +1
Using the non-relativistic effective field theory framework in a finite volume, we discuss the extraction of the transition form factors from lattice data. A counterpart of…
Partial twisting for scalar mesons
Dimitri Agadjanov, Ulf-G. Meißner, Akaki Rusetsky
The possibility of imposing partially twisted boundary conditions is investigated for the scalar sector of lattice QCD. According to the commonly shared belief, the presence of qua…
Generalization of the hypervirial and Feynman-Hellman theorems
Teimuraz Nadareishvili, Anzor Khelashvili
Using well-known methods we generalize (hyper)virial theorems to case of singular potential. Discussion is carried on for most general second order differential equation, which inv…
In connection with identification of VLF emissions before L'Aquila earthquake
M. Kachakhidze, Z. Kereselidze, N. Kachakhidze
The present paper deals with an attempt to check up the theoretical model of self-generated seismo-electromagnetic oscillations of LAI system on the basis of retrospective data. Ap…
What is the boundary condition for radial wave function of the Schrödinger equation ?
Anzor A. Khelashvili, Teimuraz P. Nadareishvili
There is much discussion in the mathematical physics literature as well as in quantum mechanics textbooks on spherically symmetric potentials. Nevertheless, there is no consensus a…
On the Boundary conditions for the Radial Schrodinger Equation
Anzor A. Khelashvili, Teimuraz P. Nadareishvili
Exploring the idea that equation for radial wave function must be compatible with the full Schrodinger equation, a boundary condition is derived.
