A patterning process utilizing a nanoimprint lithography for fabrication of planar perpendicular patterned magnetic media
… of applied research in the area of patterned magnetic media. Current magnetic media is pushing the physical limits of magnetic bits by compressing them into very small spaces - a process that will eventually be hampered by the superparamagnetic effect. The superparamagnetic effect will require …

Investigation of model micro-scale reconnecting plasma modes
… which can have finite wavelength parallel to the magnetic field, is found in the limit of a straight and uniform magnetic field in the presence of temperature gradients. The theory of the related micro-reconnecting modes has been previously developed in view of explaining the observation of …

Turbulent Dynamics Under Two Ideal Invariants: Dynamic Phase Alignment in Plasmas and Nonionized Fluids
… in low-𝛽ₑ plasmas, fluctuations of electric and magnetic potential and, in Navier-Stokes turbulence, fluctuations of velocity and vorticity. This phenomenon, termed dynamic phase alignment, thus acquires importance as a mechanism regulating the dynamics in the presence of two invariants, arising …

Physics and applications of magnetic interactions in topological insulators
… (TIs), paying particular attention to how magnetic interactions can alter their high-frequency response. To model AC transport within these materials, we develop a novel simulation framework that self-consistently solves frequency-domain quantum transport equations with the full solution of …

Radiatively Cooled Magnetic Reconnection Experiments Driven by Pulsed Power
Magnetic reconnection is a ubiquitous process in astrophysical plasmas, responsible for the explosive conversion of magnetic energy into thermal and kinetic energy. In extreme astrophysical systems, such as black hole coronae and neutron star magnetospheres, radiative cooling modifies the energy …

Experimental and computational magnetic surface mapping of the HIDRA stellarator
… and LiMIT plates on HIDRA, characterizing the magnetic configuration of the device is necessary. While previous campaigns were conducted on WEGA for the same purpose, with the disassembly and re assembly of HIDRA, the physical disposition of the coils and/or vacuum vessel may have been offset …
