Magnetic excitations in the topological semimetal YbMnSb2

We report neutron scattering measurements on YbMnSb2 which shed light on the nature of the magnetic moments and their interaction with Dirac fermions. Using half-polarized neutron diffraction we measured the field-induced magnetization distribution in the ...

A double-ended helicon source to symmetrize RAID plasma

Ivo Furno, Alan Howling, Riccardo Agnello, Marcelo Baquero Ruiz, Philippe Frédérique Bruno Guittienne, Rémy Jacquier, Christine Stollberg, Renat Karimov, Simon Pierre Henri Vincent

Neutral Beam Injectors (NBI) for post-DEMO-like reactors must achieve a neutralization efficiency (fraction neutrals/ions) above 70%. To reach this, NBIs based on negative ions are necessary and an innovative concept of this type of injector is based on ph ...

Soft Multimaterial Magnetic Fibers and Textiles

Fabien Sorin, Andreas Leber, Chaoqun Dong, Hritwick Banerjee, Stella Andréa Françoise Laperrousaz, Rémi Andréa La Polla

Magnetically responsive soft materials are promising building blocks for the next generation of soft robotics, prosthesis, surgical tools, and smart textiles. To date, however, the fabrication of highly integrated magnetic fibers with extreme aspect ratios ...

Axion assisted Schwinger effect

Valerie Fiona Domcke

We point out an enhancement of the pair production rate of charged fermions in a strong electric field in the presence of time dependent classical axion-like background field, which we call axion assisted Schwinger effect. While the standard Schwinger prod ...

Free-boundary MRxMHD equilibrium calculations using the stepped-pressure equilibrium code

Joaquim Loizu Cisquella

The stepped-pressure equilibrium code (SPEC) (Hudson et al 2012 Phys. Plasmas 19, 112 502) is extended to enable free-boundary multi-region relaxed magnetohydrodynamic (MRxMHD) equilibrium calculations. The vacuum field surrounding the plasma inside an arb ...

Quantum phase transitions and the role of impurity-substrate hybridization in Yu-Shiba-Rusinov states

Klaus Kern, Jacob Senkpiel, Haonan Huang

Spin-dependent scattering from magnetic impurities inside a superconductor gives rise to Yu-Shiba-Rusinov (YSR) states within the superconducting gap. They can be modeled by the largely equivalent Kondo or Anderson impurity models. The role of the magnetic ...

Field- and temperature-modulated spin diode effect in a GMR nanowire with dipolar coupling

Jean-Philippe Ansermet, Francesco Antonio Vetrò

The magnetization dynamics of single Co/Cu/Co spin valves, embedded in electrodeposited nanowires of 30 nm avarage diameter, was observed using the spin-diode effect. The electrically-detected magnetic resonances were compared when using modulation of eith ...

Quantum state manipulation of single atom magnets using the hyperfine interaction

Harald Brune, François Patthey, Donat Fabian Natterer, Edgar Fernandes, Dante Philippe Sblendorio

The magnetic quantum states of holmium single atom magnets on MgO(100) have proven extremely robust when exposed to high magnetic fields and temperatures up to 35 K. Here we address the stability of Ho at small magnetic fields, where the hyperfine interact ...

Diamagnetic vortices in Chern-Simons theory

Mikhail Chapochnikov, Yannis Burnier, Eray Sabancilar

We find a new type of topological vortex solution in the U(1)(Z) xU(1)(A) Chern-Simons gauge theory in the presence of a U(1)(A) magnetic field background. In this theory U(1)(Z) is broken spontaneously by the U(1)(A) magnetic field. These vortices exhibit ...

An analytical model for soil-atmosphere feedback

Bettina Schaefli

Soil-atmosphere feedback is a key for understanding the hydrological cycle and the direction of potential system changes. This paper presents an analytical framework to study the interplay between soil and atmospheric moisture, using as input only the boun ...

Spectroscopic manifestations of the Kondo effect on single adatoms

Wolf-Dieter Schneider, Markus Ternes

The present topical review focuses on recent advances concerning an intriguing phenomenon in condensed matter physics, the scattering of conduction electrons at the localized spin of a magnetic impurity: the Kondo effect. Spectroscopic signatures of this e ...

Magnetic anisotropy of paramagnetic and ferromagnetically ordered state of single crystal BaVSe3

Helmuth Berger, László Forró, Ana Akrap

Anisotropic magnetism of single crystal BaVSe3 was Studied for the first time by the combination of the susceptibility and torque methods. As reported previously for polycrystalline sample, BaVSe3 undergoes ferromagnetic ordering below 43 K. Well above fer ...

Anomaly induced effects in a magnetic field

Alexey Boyarsky, Oleg Ruchayskiy

We consider a modification of electrodynamics by an additional light massive vector field, interacting with the photon via Chern-Simons-like coupling. This theory predicts observable effects for the experiments studying the propagation of light in an exter ...

On the modulational stability of magnetic structures in electron drift turbulence

Martin Jucker

The generation of large-scale magnetic ﬁelds in magnetic electron drift mode turbulence is investigated. In particular, the mechanism of modulational instability caused by three-wave interactions is elucidated and the explicit increment is calculated. Also ...
