Re-design of EU DEMO with a low aspect ratio
The design point that had been chosen for EU DEMO in 2016 is reviewed here and a modification is proposed with a lower aspect ratio. Previously the same aspect ratio, A, was chosen for EU DEMO as in major tokamak experiments including ITER (A = 3.1), and, ...
2024Maple leaf antiferromagnet in a magnetic field
Frédéric Mila, Pratyay Ghosh, Ronny Thomale
We analyze the quantum antiferromagnet on the maple leaf lattice in the presence of a magnetic field. Starting from its exact dimer ground state and for a magnetic field strength of the order of the local dimer spin-exchange coupling, we perform a strong-c ...
College Pk2023Plasma sputtering of biased electrodes in an oblique magnetic field
Stefano Alberti, Ivo Furno, Alessandro Geraldini
The surface erosion of biased electrodes immersed in a radio frequency (RF) plasma was investigated in oblique magnetic fields ranging from 0.1 T to 3.5 T. The plasma potential and density in the vicinity of the biased electrode have been measured using an ...
IOP Publishing Ltd2023Production of a Chiral Magnetic Anomaly with Emerging Turbulence and Mean-Field Dynamo Action
In relativistic magnetized plasmas, asymmetry in the number densities of left-and right-handed fermions, i.e., a nonzero chiral chemical potential mu(5), leads to an electric current along the magnetic field. This causes a chiral dynamo instability for a u ...
AMER PHYSICAL SOC2022Hole spin qubits work at mT magnetic fields
A singlet-triplet hole spin qubit in a Ge quantum well is demonstrated to be fast, coherent, and compatible with operation at magnetic fields below 10 mT, opening the door to integration with superconducting technologies. ...
NATURE RESEARCH2021Two coupled chains are simpler than one: field-induced chirality in a frustrated spin ladder
Although the frustrated (zigzag) spin chain is the Drosophila of frustrated magnetism, our understanding of a pair of coupled zigzag chains (frustrated spin ladder) in a magnetic field is still lacking. We address this problem through nuclear magnetic reso ...
2020Chiral fermion asymmetry in high-energy plasma simulations
The chiral magnetic effect (CME) is a quantum relativistic effect that describes the appearance of an additional electric current along a magnetic field. It is caused by an asymmetry between the number densities of left- and right-handed fermions, which ca ...
2020Ablation in Externally Applied Electric and Magnetic Fields
To harness light-matter interactions at the nano-/micro-scale, better tools for control must be developed. Here, it is shown that by applying an external electric and/or magnetic field, ablation of Si and glass under ultra-short (sub-1 ps) laser pulse irra ...
2020Development and validation of a double focalizing magnetic spectrometer for beta spectrum measurements
Guido Haefeli, François Bochud
In the framework of the EMPIR project MetroBeta, the development and optimization of a double focalizing magnetic spectrometer have been realized in order to measure the beta spectra shape. The acquisition is designed to perform, after focalization by the ...
ELSEVIER2019Test Setup for Characterisation of Biased Magnetic Hysteresis Loops in Power Electronic Applications
Drazen Dujic, Min Luo, Jost Allmeling
Hysteresis effect of core materials contributes sig- nificantly to the power loss and nonlinearity of the transformers and filter inductors in power electronic applications. For design or modeling of the magnetic components, information of the magnetic mat ...
