Spontaneous PT symmetry breaking of a ferromagnetic superfluid in a gradient field

, 2015
We consider the interaction of a ferromagnetic spinor Bose-Einstein condensate with a magnetic field gradient. The magnetic field gradient realizes a spin-position coupling that explicitly breaks time-reversal symmetry T and space parity P, but preserves

Design method of magnetic resonance biplanar gradient coil based on target field method and stream function

Frontiers in Physics
The gradient coil is a crucial component of the magnetic resonance imaging (MRI) system, responsible for generating linear gradient magnetic fields to facilitate spatial positioning for image reconstruction. This article combines a new target field point

Magnetic field gradient effects on the magnetorotational instability

, 2017
The magnetorotational instability (MRI), also known as the Balbus -- Hawley instability, is thought to have an important role on the initiation of turbulence and angular momentum transport in accretion discs.

The influence of longitudinal magnetic-field gradient on the transverse relaxation rate of cesium atoms

AIP Advances, 2017
Reducing the transverse relaxation rate of alkali atoms is crucial to improve the sensitivity of the magnetometers. In a perturbative treatment of the effects of the magnetic-field gradients, the transverse relaxation rates of alkali atoms are predicted ...

A Robust Tracking Method for Multiple Moving Targets Based on Equivalent Magnetic Force

Micromachines, 2022
A ferromagnetic vehicle, such as a submarine, magnetized by the Earth’s magnetic field produces a magnetic anomaly field, and the tracking of moving targets can be realized through real-time analysis of magnetic data.

Generation of spin-motion entanglement in a trapped ion using long-wavelength radiation [PDF]

, 2014
Applying a magnetic-field gradient to a trapped ion allows long-wavelength radiation to produce a mechanical force on the ion's motion when internal transitions are driven.

A Lagrangian model for the evolution of turbulent magnetic and passive scalar fields [PDF]

, 2010
In this paper we present an extension of the \emph{Recent Fluid Deformation (RFD)} closure introduced by Chevillard and Meneveau (2006) which was developed for modeling the time evolution of Lagrangian fluctuations in incompressible Navier-Stokes ...
