Magnetic Confinement of a Bubble of Supercooled <sup>3</sup>He-A. [PDF]
J Low Temp PhysAbstract We have designed and constructed a magnet surrounding a cylindrical volume of superfluid helium-3 to isolate a region of metastable, supercooled A phase, entirely surrounded by bulk A phase - isolating the ‘bubble’ from rough surfaces that can trigger the transition to the stable B phase.

Magnetic Skyrmions Under Confinement
Communications in Mathematical Physics, 2023 AbstractWe present a variational treatment of confined magnetic skyrmions in a minimal micromagnetic model of ultrathin ferromagnetic films with interfacial Dzylashinksii-Moriya interaction (DMI) in competition with the exchange energy, with a possible addition of perpendicular magnetic anisotropy. Under Dirichlet boundary conditions that are motivated

Magnetic confinement and screening masses [PDF]
Physics Letters B, 1995 Confined and deconfined phases are defined through nonperturbative correlators and nonperturbative background perturbation theory is used to compute the critical temperature $T_c$ and spatial string tension. Taking evolution along one of the spatial axes the set of Hamiltonians $H(n_1,n_2)$ with different Matsubara frequencies is obtained.

Fluid Drag Reduction by Magnetic Confinement
Langmuir, 2022 The frictional forces of a viscous liquid flow are a major energy loss issue and severely limit microfluidics practical use. Reducing this drag by more than a few tens of percent remain illusive. Here, we show how cylindrical liquid-in-liquid flow leads to drag reduction of 60-99% for sub mm and mm sized channels, irrespective of whether the viscosity ...

Quantized Magnetic Confinement in Quantum Wires [PDF]
Physical Review Letters, 2010 Ballistic quantum wires are exposed to longitudinal profiles of perpendicular magnetic fields composed of a spike (magnetic barrier) and a homogeneous part. An asymmetric magnetoconductance peak as a function of the homogeneous magnetic field is found, comprising quantized conductance steps in the interval where the homogeneous magnetic field and the ...

Experimental study of electron cyclotron heating assisted start-up on J-TEXT
Nuclear Fusion, 2023 Second harmonic X-mode (X2 mode) electron cyclotron heating (ECH) assisted start-up has been studied experimentally on the J-TEXT device to determine the minimum ECH power requirements to assist breakdown and develop a better physical description of the ...
