Magnetic microchains and microswimmers in an oscillating magnetic field [PDF]

Biomicrofluidics, 2016
Superparamagnetic micro-bead chains and microswimmers under the influence of an oscillating magnetic field are studied experimentally and numerically. The numerical scheme composed of the lattice Boltzmann method, immersed boundary method, and discrete particle method based on the simplified Stokesian dynamics is applied to thoroughly understand the ...

Photospheric high-frequency acoustic power excess in sunspot umbra: signature of magneto-acoustic modes [PDF]

, 2013
We present observational evidence for the presence of MHD (magnetohydrodynamic) waves in the solar photosphere deduced from SOHO/MDI (Solar and Heliospheric Observatory/Michelson Doppler Imager) Dopplergram velocity observations.

Performance- and stimulus-dependent oscillations in monkey prefrontal cortex during short-term memory [PDF]

, 2009
Short-term memory requires the coordination of sub-processes like encoding, retention, retrieval and comparison of stored material to subsequent input. Neuronal oscillations have an inherent time structure, can effectively coordinate synaptic integration

Hypersound excitation of magnetization and elastic displacement in case of magnetization reversal

EPJ Web of Conferences, 2018
The paper gives a description of hypersound magnetoelastic oscillations excitation along magnetisation reversal of normal magnetized single-layer and multi-layers ferrite plates, also provides definition of distinctive features of magnetic and elastic ...

High-mobility two-dimensional carriers from surface Fermi arcs in magnetic Weyl semimetal films

npj Quantum Materials, 2022
High-mobility two-dimensional carriers originating from surface Fermi arcs in magnetic Weyl semimetals are highly desired for accessing exotic quantum transport phenomena and for topological electronics applications.

Magnetic oscillations in silicene [PDF]

Journal of Magnetism and Magnetic Materials, 2018
In this work the magnetic oscillations (MO) in pristine silicene at $T=0$ K are studied. Considering a constant electron density we obtain analytical expressions for the ground state internal energy and magnetization, under a perpendicular electric and magnetic field, taking in consideration the Zeeman effect. It is found that the MO are sawtooth-like,

Photospheric magnetic vortex structures [PDF]

, 2011
Using direct numerical magneto-hydrodynamic (MHD) simulations, we demonstrate the evidence of two physically different types of vortex motions in the solar photosphere.

Bulk-boundary quantum oscillations in inhomogeneous Weyl semimetals

New Journal of Physics, 2020
In a Weyl semimetal, a spatially inhomogeneous Weyl node separation caused by lattice deformations can mimic the action of axial electromagnetic fields.

On the location of dayside magnetic reconnection during an interval of duskward oriented IMF [PDF]

, 2007
We present space- and ground-based observations of the signatures of magnetic reconnection during an interval of duskward-oriented interplanetary magnetic field on 25 March 2004.
