Investigation of Jet Mixing Characteristics Using Slotted Rectangular Tabs [PDF]

open access: yesJournal of Aerospace Technology and Management, 2021
This article discusses the jet mixing effectiveness of rectangular tab with slots to distort the jet, thereby creating vortices of differing sizes to enhance the mixing.

Spontaneous Formations of Dynamical Steady States in Polariton Condensates

open access: yesFrontiers in Physics, 2021
We present a numerical analysis on dynamical steady states of polariton Bose–Einstein condensates (BECs) in an incoherent exciton reservoir driven by a ring-shaped optical pump.

Switching and instabilities of optical vortices in nonlinear dual-core photonic crystal fibre couplers [PDF]

open access: yesJournal of the European Optical Society-Rapid Publications, 2006
We study switching of an optical vortex launched into one core of a dual-core waveguide coupler in a photonic crystal fibre with self-focusing nonlinearity.

Current configurations in long Josephson contact in an external magnetic field

open access: yesSt. Petersburg Polytechnical University Journal: Physics and Mathematics, 2021
Current configurations in a periodically modulated long Josephson contact located in an external magnetic field are considered for values of the pinning parameter I greater than and less than the critical one.

Casimir Force between Two Vortices in a Turbulent Bose–Einstein Condensate

open access: yesAtoms, 2020
We consider the Casimir force between two vortices due to the presence of density fluctuations induced by turbulent modes in a Bose–Einstein condensate. We discuss the cases of unbounded and finite condensates.

Superheating field in superconductors with nanostructured surfaces

open access: yesFrontiers in Electronic Materials, 2023
We report calculations of a DC superheating field Hsh in superconductors with nanostructured surfaces. Numerical simulations of the Ginzburg–Landau (GL) equations were performed for a superconductor with an inhomogeneous impurity concentration, a thin ...

Deep Minima in the Triply Differential Cross Section for Ionization of Atomic Hydrogen by Electron and Positron Impact

open access: yesAtoms, 2020
We investigate ionization of atomic hydrogen by electron- and positron-impact. We apply the Coulomb–Born (CB1) approximation, various modified CB1 approximations, the three body distorted wave (3DW) approximation, and the time-dependent close-coupling ...
