Polarization control in spin-transparent hadron colliders by weak-field navigators involving lattice enhancement effect

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
Hadron polarization control schemes for Spin Transparent (ST) synchrotrons are analyzed. The spin dynamics and beam polarization in such synchrotrons are controlled by spin navigators (SN) which are special small insertions of weak magnetic fields. An SN

Spin-polarized transport in a quasi-1D wire with Rashba dots

open access: yesAIP Advances, 2018
A numerical study on spin-polarized transport properties in a quasi-one-dimensional wire with Rashba quantum dots is presented. The ballistic spin transmission probability and spin density profiles are obtained using the quantum transmitting boundary ...

Rashba coupling and spin switching through surface states of Dirac semimetals

open access: yesNew Journal of Physics, 2021
We study the effect of the Rashba spin–orbit coupling on the Fermi arcs of topological Dirac semimetals. The Rashba coupling is induced by breaking the inversion symmetry at the surface. Remarkably, this coupling could be enhanced by the interaction with

Complex Dynamic Behaviors of a Modified Discrete Leslie–Gower Predator–Prey System with Fear Effect on Prey Species

open access: yesAxioms, 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.

Spin-helix Larmor mode

open access: yesScientific Reports, 2018
A two-dimensional electron gas (2DEG) with equal-strength Rashba and Dresselhaus spin-orbit coupling sustains persistent helical spin-wave states, which have remarkably long lifetimes.

The Isotropic Center of NGC 5419—A Core in Formation?

open access: yesThe 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.

Spin-orbit coupling, electron transport and pairing instabilities in two-dimensional square structures

open access: yesAIP Advances, 2016
Rashba spin-orbit effects and electron correlations in the two-dimensional cylindrical lattices of square geometries are assessed using mesoscopic two-, three- and four-leg ladder structures.

Defected twisted ring topology for autonomous periodic flip–spin–orbit soft robot

open access: yesProceedings of the National Academy of Sciences of the United States of America
Significance Topology and defect are crucial for autonomous soft mobile machines made of soft materials since they can dramatically change materials’ responses. However, their interplay on autonomous motion remains largely unexplored.

Resonant Homoclinic Bifurcations with Orbit Flips and Inclination Flips

open access: yesApplied 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 ...
