Kink in dual dilaton-axion theories with potential
Oleg V. Kechkin
The representation in terms of Ernst's complex potential is used to describe and analyze dilaton-axion theories with potential. The set of such systems is divided into pairs of dua…
Kink in the dilaton-axion theory with a potential possessing dilaton shift symmetry
Oleg V. Kechkin
The sigma model with dilaton and axion is generalized by including in it a potential that is invariant under the global transformation of the dilaton shift. In the (1 + 1)-dimensio…
Structures of General Relativity in Dilaton-Maxwell Electrodynamics
Oleg V. Kechkin, Pavel A. Mosharev
It is shown that electro (magneto) static sector of Maxwell's electrodynamics coupled to the dilaton field in a string theory form possesses the symmetry group of the stationary Ge…
Singularity-free interaction in dilaton-Maxwell electrodynamics
Oleg Kechkin, Pavel Mosharev
An effective potential is created for the dynamics of a test particle, which preserves dilatation symmetry for nonlinear static dilaton-Maxwell background. It is found that the cen…
Absolute Time and Temperature in Quantum and Classical Relativistic Mechanics
Vadim V. Asadov, Oleg V. Kechkin
We present a relativistic quantum mechanics of a point mass with absolute thermodynamic time and temperature, combined to a single complex parameter of evolution. In this theory, t…
Classical Dynamics of Quantum Numbers with Arrow of Time
Vadim V. Asadov, Oleg V. Kechkin
We study a quantum theory with complex time parameter and non-Hermitian Hamiltonian structure. In this theory, the real part of the complex time is equal to `usual' physical time,…
