Advanced Science, EarlyView.A versatile framework integrates addressable electrothermal actuation and strain‐constraint mechanisms to construct programmable shape‐morphing soft matter systems. By combining an analytical inverse design strategy for high‐fidelity 3D surface reconstruction with deep learning‐based closed‐loop control, this approach enables zero‐energy shape locking,

Evolution of magnetic helicity under kinetic magnetic reconnection: Part II B ≠ 0 reconnection [PDF]
Nonlinear Processes in Geophysics, 2002 We investigate the evolution of magnetic helicity under kinetic magnetic reconnection in thin current sheets. We use Harris sheet equilibria and superimpose an external magnetic guide field.

Kinetic Simulations of Radiative Magnetic Reconnection in the Coronae of Accreting Black Holes [PDF]
Astrophysical Journal, 2019 We perform 2D and 3D particle-in-cell simulations of reconnection in magnetically dominated e± plasmas subject to strong Compton cooling. Magnetic reconnection under such conditions can operate in accretion disk coronae around black holes, which produce ...

The Magnetic Reconnection Code: Center for Magnetic Reconnection Studies [PDF]
, 2007 Understanding magnetic reconnection is one of the principal challenges in plasma physics. Reconnection is a process by which magnetic fields reconfigure themselves, releasing energy that can be converted to particle energies and bulk flows. Thanks to the availability of sophisticated diagnostics in fusion and laboratory experiments, in situ probing of ...

Relativistic Magnetic Reconnection in Electron–Positron–Proton Plasmas: Implications for Jets of Active Galactic Nuclei [PDF]
Astrophysical Journal, 2019 Magnetic reconnection is often invoked to explain the nonthermal radiation of relativistic outflows, including jets of active galactic nuclei (AGNs). Motivated by the largely unknown plasma composition of AGN jets, we study reconnection in the unexplored

Magnetic Reconnection Rate in the M6.5 Solar Flare on 2015 June 22
The Astrophysical Journal, 2023 Magnetic reconnection is regarded as the mechanism for the rapid release of magnetic energy stored in active regions during solar flares, and quantitative measurements of the magnetic reconnection rate are essential for understanding solar flares. In the
