Quantum printing and induced vorticity in superconductors II: Laguerre-Gaussian beam
Physical Review ResearchThe challenge of controlling the quantum states of matter via light has been at the forefront of modern research on driven quantum matter. We explore the imprinting effects of structured light on superconductors, demonstrating how the quantum numbers of ...

Switching and instabilities of optical vortices in nonlinear dual-core photonic crystal fibre couplers [PDF]
Journal of the European Optical Society-Rapid Publications, 2006 We study switching of an optical vortex launched into one core of a dual-core waveguide coupler in a photonic crystal fibre with self-focusing nonlinearity.

Current-driven vortex dynamics in untwinned superconducting single crystals [PDF]
, 1997 Current-driven vortex dynamics of type-II superconductors in the weak-pinning limit is investigated by quantitatively studying the current-dependent vortex dissipation of an untwinned YBa2Cu3O7 single crystal.

Transverse vortex dynamics in superconductors [PDF]
Physical Review B, 2006 We experimentally characterize the transverse vortex motion and observed some striking features. We found large structures and peaks in the Hall resistance, which can be attributed to the long-range inhomogeneous vortex flow present in some phases of vortex dynamics. We further demonstrate the existence of a moving vortex phase between the pinned phase

Systemic dysregulation of apolipoproteins in amyotrophic lateral sclerosis serum
FEBS Open Bio, EarlyView.Amyotrophic lateral sclerosis (ALS) is a fatal disease that damages motor neurons. This study found that people with ALS show significant changes in blood fats and the proteins that carry them. Several apolipoproteins were higher, lipid balances were altered, and normal protein–lipid relationships were disrupted.

Fractional Vortex Dynamics in Two-Band Superconductors with Linear Normal Strips
CrystalsWe investigate the impact of normal linear strips—both perpendicular and parallel to the direction of vortex motion—on the dynamics of fractional vortices in a two-band superconducting slab.

Imaging Spin Dynamics on the Nanoscale using X-Ray Microscopy
Frontiers in Physics, 2015 The dynamics of emergent magnetic quasiparticles, such as vortices, domain walls, and bubbles are studied by scanning transmission x-ray microscopy (STXM), combining magnetic (XMCD) contrast with about 25 nm lateral resolution as well as 70 ps time ...

Aerodynamic sound generated by the collision of a vortex pair with a corner
Nihon Kikai Gakkai ronbunshu, 2021 This study investigates the mechanisms of the aerodynamic sound emitted by the collision of a vortex pair with a corner. When the vortex pair collides with the corner of a wall at a 45° angle of incidence, a reflection-symmetric vortex motion is observed,

Noisy Dynamics of a Vortex in a Partially Bose-Einstein Condensed Gas
, 2003 We study the dynamics of a straight vortex line in a partially Bose-Einstein condensed atomic gas. Using a variational approach to the stochastic field equation that describes the dynamics of the condensate at nonzero temperature, we derive the ...

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Background Myasthenia gravis (MG) is a rare disorder characterized by fluctuating muscle weakness with potential life‐threatening crises. Timely interventions may be delayed by limited access to care and fragmented documentation. Our objective was to develop predictive algorithms for MG deterioration using multimodal telemedicine data ...
