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.

Orbital Flips Caused by the Eccentric Von Zeipel–Lidov–Kozai Effect in Nonrestricted Hierarchical Planetary Systems

open access: yesThe Astronomical Journal, 2022
Abstract The eccentric von Zeipel–Lidov–Kozai effect is widely applied to diverse astrophysical settings. In the restricted hierarchical three-body system, the topic of orbital flips has been extensively studied. However, it is far from being understood for nonrestricted circumstances.

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 ...

Pulse-adding of temporal dissipative solitons: resonant homoclinic points and the orbit flip of case B with delay

open access: yesNonlinearity, 2023
Abstract We numerically investigate the branching of temporally localised, two-pulse solutions from one-pulse periodic solutions with non-oscillating tails in delay differential equations (DDEs) with large delay. Solutions of this type are commonly referred to as temporal dissipative solitons (TDSs) (Yanchuk et al 2019 Phys. Rev. Lett.

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 Planet Nine Hypothesis [PDF]

open access: yes, 2019
Over the course of the past two decades, observational surveys have unveiled the intricate orbital structure of the Kuiper Belt, a field of icy bodies orbiting the Sun beyond Neptune.

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.

Kneadings, Symbolic Dynamics and Painting Lorenz Chaos. A Tutorial

open access: yes, 2012
A new computational technique based on the symbolic description utilizing kneading invariants is proposed and verified for explorations of dynamical and parametric chaos in a few exemplary systems with the Lorenz attractor.

Two-dimensional localized structures in harmonically forced oscillatory systems [PDF]

open access: yes, 2016
Two-dimensional spatially localized structures in the complex Ginzburg–Landau equation with 1:1 resonance are studied near the simultaneous presence of a steady front between two spatially homogeneous equilibria and a supercritical Turing bifurcation on ...
