Axioms, 2022 A discrete modified Leslie–Gower prey-predator model considering the effect of fear on prey species is proposed and studied in this paper. First, we discuss the existence of equilibria and the local stability of the model.

The Isotropic Center of NGC 5419—A Core in Formation?
The Astrophysical Journal, 2023 With its cored surface brightness profile, the elliptical galaxy NGC 5419 appears as a typical high-mass early-type galaxy (ETG). However, the galaxy hosts two distinct nuclei in its center.

Direct-retrograde orbit flips at planetary close encounters
Astronomy & Astrophysics, 2022 Aims. We want to find the conditions under which planetary close encounters transform the orbits of small Solar System bodies from direct to retrograde, and vice versa. Methods. We derive analytical constraints on the orbital elements of the small body that allow direct-retrograde transitions at close encounters. We check the validity of the analytical

Ab initio spin-flip conductance of hydrogenated graphene nanoribbons: spin- orbit interaction and scattering with local impurity sites [PDF]
, 2015 We calculate the spin-dependent zero-bias conductance G(sigma sigma ') in armchair graphene nanoribbons with hydrogen adsorbates employing a DFT-based ab initio transport formalism including spin-orbit interaction.

Resonant Homoclinic Bifurcations with Orbit Flips and Inclination Flips
Applied Mathematics, 2013 Homoclinic bifurcation with one orbit flip, two inclination flips and resonance in the tangent directions of homoclinic orbit is considered. By studying the associated successor functions constructed from a local active coordinate system, we prove the existence of double 1-periodic orbit, 1-homoclinic orbit, and also some coexistence conditions of 1 ...

Qubit gates with simultaneous transport in double quantum dots
New Journal of Physics, 2018 A single electron spin in a double quantum dot in a magnetic field is considered in terms of a four-level system. By describing the electron motion between the potential minima via spin-conserving tunneling and spin flip caused by a spin–orbit coupling ...

Semiconductor spintronics in a participating phonon medium: Macroscopic equations
AIP Advances, 2013 In the last two decades considerable interest has arisen on the spin related phenomena in semiconductor devices. In semiconductor materials two essential mechanisms act on the spin dynamics: the spin-orbit coupling and the spin-flip interactions.
