Chaos of Charged Particles in Quadrupole Magnetic Fields Under Schwarzschild Backgrounds

Universe
A four-vector potential of an external test electromagnetic field in a Schwarzschild background is described in terms of a combination of dipole and quadrupole magnetic fields. This combination is an interior solution of the source-free Maxwell equations.

Nuclear Magnetic Quadrupole Moments in Single Particle Approximation

, 1994
A static magnetic quadrupole moment of a nucleus, induced by T- and P-odd nucleon-nucleon interaction, is investigated in the single-particle approximation. Models are considered allowing for analytical solution.

Enhanced long-range quadrupole effects in 2D MSi2N4: impacts on electric and thermal transport

npj Computational Materials
Long-range higher-order multipolar electron–phonon (e-ph) interactions beyond the dipole-like Fröhlich interactions have long been neglected in the description of various physical properties. Here we demonstrate the contribution from quadrupole effect to

Collective oscillations of Bose-Einstein condensates in a synthetic magnetic field

Physical Review Research
We study the collective oscillations of spin-orbit-coupled Bose-Einstein condensates in the presence of position-dependent detuning. Specifically, we explore the quadrupole modes of the system using both numerical and analytical approaches based on the ...
