Branched Josephson junctions: Current carrying solitons in external magnetic fields

Autor: Sabirov, K., Babajanov, D., Matrasulov, D., Susanto, H.

Publikováno v: EPL, 130 (2020) 67002

We consider branched Josephson junction created by planar superconductors connected to each other through the Y-junction insulator. Assuming that the structure interacts with the external constant magnetic field, we study static sine-Gordon solitons

Charged solitons in branched conducting polymers

Autor: Babajanov, D., Matyoqubov, H., Matrasulov, D.

Publikováno v: J. Chem. Phys. 149, 164908 (2018)

We consider dynamics of charged solitons in branched conducting polymers. An effective model based on the sine-Gordon equation on metric graphs is used for computing the charge transport and scattering of charge carriers at the polymer branching poin

Thermal diffusion in branched structures: Metric graph based approach

Autor: Sabirov, K., Zhunussova, Zh., Babajanov, D., Matrasulov, D.

We consider the problem of heat diffusion in branched systems and networks on the basis of a model described in terms of heat equation on metric graphs. Using the explicit analytical solutions of the latter, evolution of the temperature profile and h

Nonlinear standing waves on planar branched systems: Shrinking into metric graph

Autor: Sobirov, Z., Babajanov, D., Matrasulov, D.

Publikováno v: NANOSYSTEMS: PHYSICS, CHEMISTRY, MATHEMATICS. 8, 29 (2017)

We treat the stationary nonlinear Schroodinger equation on two-dimensional branched domains, so-called fat graphs. The shrinking limit when the domain becomes one-dimensional metric graph is studied by using analytical estimate of the convergence of

Dynamics of Dirac solitons in networks

Autor: Sabirov, K. K., Babajanov, D. B., Matrasulov, D. U., Kevrekidis, P. G.

Publikováno v: J. Phys. A: Math. Theor. 51 (2018) 435203

We study dynamics of Dirac solitons in prototypical networks modeling them by the nonlinear Dirac equation on metric graphs. Soliton solutions of the nonlinear Dirac equation on simple metric graphs are obtained. It is shown that these solutions prov

Particle Transport in Graphene Nanoribbon Driven by Ultrashort Pulses

Autor: Babajanov, D., Matrasulov, D. U., Egger, R.

Publikováno v: Page 1 Eur. Phys. J. B (2014) 87: 258

We study charge transport in a graphene zigzag nanoribbon driven by an external time-periodic kicking potential. Using the exact solution of the time-dependent Dirac equation with a delta-kick potential acting in each period, we study the time evolut

Autor: Sapaev I. B., Sadullaev S., Babajanov D., Sapaev B., Umarov A. V., Pulatov Sh. Y., Meliziaev O. O., Daliev K. S.

Publikováno v: E3S Web of Conferences, Vol 413, p 04009 (2023)

Heterojunction between Si and CdSxTe1-x have been obtained by the method of vacuum deposition of powders of cadmium sulfide and cadmium telluride on the surface of monocrystalline silicon. The optimal temperature regime for the growth of the CdSxTe1-
