Laminar and transiently disordered dynamics of magnetic-skyrmion pipe flow

X Zhang, J Xia, OA Tretiakov, M Ezawa, G Zhao… - Physical Review B, 2023 - APS
The world is full of fluids that flow. The fluid nature of flowing skyrmionic quasiparticles is of
fundamental physical interest and plays an essential role in the transport of many skyrmions …

Active crystals on a sphere

S Praetorius, A Voigt, R Wittkowski, H Löwen - Physical Review E, 2018 - APS
Two-dimensional crystals on curved manifolds exhibit nontrivial defect structures. Here we
consider “active crystals” on a sphere, which are composed of self-propelled colloidal …

Shear banding, intermittency, jamming, and dynamic phases for skyrmions in inhomogeneous pinning arrays

C Reichhardt, CJO Reichhardt - Physical Review B, 2020 - APS
We examine driven skyrmion dynamics in systems with inhomogeneous pinning where a
strip of strong pinning coexists with a region containing no pinning. For driving parallel to the …

Rectification of vortex motion in a circular ratchet channel

NS Lin, TW Heitmann, K Yu, BLT Plourde… - Physical Review B …, 2011 - APS
We study the dynamics of vortices in an asymmetric (ie, consisting of triangular cells) ring
channel driven by an external ac current I in a Corbino setup. The asymmetric potential …

Intrinsic statistical regularity of topological charges revealed in dynamical disk model

R Sun, Z Yao - Physical Review E, 2024 - APS
Identifying ordered structures hidden in the packings of particles is a common scientific
question in multiple fields. In this work, we investigate the dynamical organizations of a large …

Plastic instability of annular crystalline membrane in circular confinement

H Sun, Z Yao - Physical Review E, 2024 - APS
Understanding the mechanical instabilities of two-dimensional membranes has strong
connection to the subjects of structure instabilities, morphology control, and materials …

Extruding the vortex lattice: Two reacting populations of dislocations

JS Watkins, NK Wilkin - Europhysics Letters, 2019 - iopscience.iop.org
A controllable soft solid is realised in vortex matter (Eskildsen MR et al., Rep. Prog. Phys., 74
(2011) 124504; Guillamon I. et al., Nat. Phys., 10 (2014) 851; Lukyanchuk I. et al., Nat. Phys …

Two-shell vortex and antivortex dynamics in a Corbino superconducting disk

LRE Cabral, BR de Aquino, CCS Silva, MV Milošević… - Physical Review B, 2016 - APS
We examine theoretically the dynamics of two vortex shells in pinning-free superconducting
thin disks in the Corbino geometry. In the first considered case, the inner shell is composed …

Macroscopic random telegraph noise

G Jung - Fluctuation and Noise Letters, 2019 - World Scientific
It is proposed that macroscopic telegraph noise in superconductors is due to dynamic
coexistence of ordered and disordered vortex phases (DP and OP) created by edge …

High performance Ginzburg-Landau simulations of superconductivity

D Stosic - 2018 - bdtd.ibict.br
Superconductivity is one of the most important discoveries of the last century. With many
applications in physics, engineering, and technology, superconductors are crucial to our …
