physics community, as well as a broad introduction to the statistical theories of forced rigid …

Transition from reversible to irreversible flow: Absorbing and depinning transitions in a sheared-vortex system

S Okuma, Y Tsugawa, A Motohashi - Physical Review B—Condensed Matter …, 2011‏ - APS
We provide evidence that a reversible to irreversible flow transition (RIT), as reported in
driven colloidal particles, occurs in periodically sheared vortices in a Corbino-disk …

How the vortex lattice of a superconductor becomes disordered: a study by scanning tunneling spectroscopy

M Zehetmayer - Scientific Reports, 2015‏ - nature.com
Order-disorder transitions take place in many physical systems, but observing them in detail
in real materials is difficult. In two-or quasi-two-dimensional systems, the transition has been …

Evidence of second-order transition and critical scaling for the dynamical ordering transition in current-driven vortices

S Maegochi, K Ienaga, S Okuma - Scientific Reports, 2024‏ - nature.com
Dynamical ordering from a disordered plastic flow to an anisotropically ordered smectic flow
induced by a dc force has been studied in various many-particle systems, including vortices …

Memory formation and evolution of the vortex configuration associated with random organization

M Dobroka, Y Kawamura, K Ienaga… - New Journal of …, 2017‏ - iopscience.iop.org
We study the general phenomenon of random organization using a vortex system. When a
periodic shear with a small shear amplitude d inp is applied to many-particle (vortex) …

Debye screening of dislocations

I Groma, G Györgyi, B Kocsis - Physical review letters, 2006‏ - APS
Debye-like screening by edge dislocations of some externally given stress is studied by
means of a variational approach to coarse grained field theory. Explicitly given are the force …

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 …

Probability distribution of internal stress in relaxed dislocation systems

FF Csikor, I Groma - Physical Review B—Condensed Matter and Materials …, 2004‏ - APS
The probability distribution of the internal shear stress generated by systems of straight,
parallel edge dislocations is studied. The stress distribution functions of randomly distributed …

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 …

MH Vainstein, IVL Costa, FA Oliveira - Jamming, Yielding, and Irreversible …, 2006‏ - Springer
Complex systems such as glasses, gels, granular materials, and systems far from
equilibrium exhibit violation of the ergodic hypothesis (EH) and of the fluctuation-dissipation …
