Magnetic breakdown spectrum of a Kramers–Weyl semimetal

New Journal of Physics, 2020
We calculate the Landau levels of a Kramers–Weyl semimetal thin slab in a perpendicular magnetic field B . The coupling of Fermi arcs on opposite surfaces broadens the Landau levels with a band width that oscillates periodically in 1/ B .

Neural oscillators for magnetic hysteresis modeling

CoRR, 2023
Hysteresis is a ubiquitous phenomenon in science and engineering; its modeling and identification are crucial for understanding and optimizing the behavior of various systems. We develop an ordinary differential equation-based recurrent neural network (RNN) approach to model and quantify the hysteresis, which manifests itself in sequentiality and ...

Spatial antiferromagnetic spin texture as a nano-oscillator

Scientific Reports, 2023
We report a theoretical study of the localized spatial magnetization configuration, which is a confined spin configuration of the target skyrmion/hopfion type in an antiferromagnet with perpendicular magnetic anisotropy, and then we solve the particular ...

Evidence of Transverse Magnetospheric Field Line Oscillations as Observed from Cluster and Ground Magnetometers [PDF]

, 2005
The dynamic spectrum of ULF waves from magnetic field data obtained by the elliptically orbiting Cluster satellites (with an apogee of 119 000 km, perigee of 19 000 km and the orbital period of 57 h) have been prepared in the frequency range 0 to 120 mHz

Detection of fast oscillating magnetic fields using dynamic multiple TR imaging and Fourier analysis. [PDF]

PLoS ONE, 2018
Neuronal oscillations produce oscillating magnetic fields. There have been trials to detect neuronal oscillations using MRI, but the detectability in in vivo is still in debate. Major obstacles to detecting neuronal oscillations are (i) weak amplitudes, (

Magnetic oscillations of a fractional Hall dot [PDF]

Physical Review Letters, 1993
We show that a quantum dot in the fractional Hall regime exhibits mesoscopic magnetic oscillations with a period which is a multiple of the period for free electrons. Our calculations are performed for parabolic quantum dots with hard-core electron-electron interactions and are exact in the strong field limit for $k_B T$ smaller than the fractional ...

Range finding of Alfvén oscillations and direction finding of ion-cyclotron waves by using the ground-based ULF finder [PDF]

, 1996
International audienceA new approach to the problem of direction and distance finding of magnetospheric ULF oscillations is described. It is based on additional information about the structure of geoelectromagnetic field at the Earth's surface which is ...

Neutrino eigenstates and flavour, spin and spin-flavour oscillations in a constant magnetic field

European Physical Journal C: Particles and Fields, 2019
We further develop a recently proposed new approach to the description of the relativistic neutrino flavour $$\nu _e^L \leftrightarrow \nu _{\mu }^L$$ νeL↔νμL , spin $$\nu _e^L \leftrightarrow \nu _{e}^R$$ νeL↔νeR and spin-flavour $$\nu _e^L ...
