Decay Process of a Magnetic Island by Forced Reconnection

, 1991
"Time evolution of a magnetic island by forced reconnection, especially the decay process is analyzed. A simple slab model is used and the magnetic island is considered to have a single helicity. The plasma is assumed to be incompressible.

Elasticity‐Driven Periodic Polarization Patterns in a Chiral Ferroelectric Nematic Fluid

Advanced Materials, EarlyView.
Chiral polar ferroelectric nematic fluids exhibit spontaneous formation of stripe, square, and hexagonal polarization textures under confinement. Controlled by thickness and anchoring, these patterns produce spatially modulated nonlinear optical responses.

Physics-guided attention-aware convolutional neural networks for identification of magnetic islands in the tearing mode on EAST tokamak

Nuclear Fusion
The tearing mode (TM), a large-scale magnetohydrodynamic instability in tokamak, typically disrupts the equilibrium magnetic surfaces, leads to the formation of magnetic islands, reduces core electron temperature and density, thus resulting in ...
