Calibration of Model Parameters in Navigation Devices Based on Fiber-Optic Gyroscopes
Autor: V. N. Likhachev, Victor Semenovich Yaroshevsky, Oleg Vsevolodovich Trifonov
Publikováno v: Mathematical Models and Computer Simulations. 12:676-684
The features of navigation devices based on fiber-optic gyroscopes cause problems in their practical applications and require calibration prior to being used. The algorithms for accumulating and processing the information of strapdown inertial blocks

Solving a Discrete Nonlinear Schrödinger Equation with a Trap
Autor: N. S. Erikhman, George A Vinogradov, V. N. Likhachev
Publikováno v: Russian Journal of Physical Chemistry B. 14:391-394
The wave function and ground state energy for a discrete nonlinear Schrodinger equation (DNLSE) with a trap can be found numerically using an iterative process. However, this approach does not always give convergent results. A functional is proposed

Polaron on a Lattice with a Trap in the Su–Schrieffer–Heeger Approximation
Autor: V. N. Likhachev, George A Vinogradov
Publikováno v: Russian Journal of Physical Chemistry B. 14:222-226
The wave function and energy of the ground state of a lattice described by the Su–Schrieffer–Heeger Hamiltonian with a trap were found using three different methods. In the first of these methods, the energy of the ground state was calculated by

Solutions of the Discrete Nonlinear Schrödinger Equation with a Trap
Autor: V. N. Likhachev, G. A. Vinogradov
Publikováno v: Theoretical and Mathematical Physics. 201:1771-1778
We obtain solutions of the discrete nonlinear Schrodinger equation with an impurity center in two ways. In the first of them, we construct the wave function as a series in a certain parameter. In the second, approximate method, we obtain the wave fun

Quantum Problem of Polaron Localization and Justification of the Su—Schrieffer—Heeger Approximation
Autor: V. N. Likhachev, G. A. Vinogradov
Publikováno v: Theoretical and Mathematical Physics. 199:719-725
We consider a polaron localized on a trap in a one-dimensional lattice with a harmonic potential of nearest-neighbor interaction. We study the lattice oscillations in the framework of quantum mechanics and regard the polaron energy as a functional of
