Magnetic excitations in the topological semimetal YbMnSb2

Jian Rui Soh

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 ...

Energetics and cathode voltages of LiMPO4 olivines (M = Fe, Mn) from extended Hubbard functionals

Nicola Marzari, Matteo Cococcioni

Transition-metal compounds pose serious challenges to first-principles calculations based on density functional theory (DFT), due to the inability of most approximate exchange-correlation functionals to capture the localization of valence electrons on thei ...

High-beta, steady-state hybrid scenario on DIII-D

Holger Reimerdes

The potential of the hybrid scenario (first developed as an advanced inductive scenario for high fluence) as a regime for high-beta, steady-state plasmas is demonstrated on the DIII-D tokamak. These experiments show that the beneficial characteristics of h ...

Towards the non-perturbative cosmological bootstrap

João Miguel Augusto Penedones Fernandes, Kamran Salehi Vaziri, Matthijs Jan Hogervorst

We study quantum field theory on a de Sitter spacetime dS(d+1) background. Our main tool is the Hilbert space decomposition in irreducible unitary representations of its isometry group SO(d + 1, 1). As the first application of the Hilbert space formalism, ...

Tritium removal from JET-ILW after T and D-T experimental campaigns

Henri Weisen, Mikhail Maslov

After the second Deuterium-Tritium Campaign (DTE2) in the JET tokamak with the ITER-Like Wall (ILW) and full tritium campaigns that preceded and followed after the DTE2, a sequence of fuel recovery methods was applied to promote tritium removal from wall c ...

Electron-cyclotron-current-drive efficiency in DEMO plasmas

Laurie Porte, Emiliano Fable

The achievable efficiency for external current drive through electron-cyclotron waves in a demonstration tokamak reactor is investigated. Two possible reactor designs, one for steady state and one for pulsed operation, are considered. Beam propagation, abs ...

Ion-Selective Scattering Studied Using the Variable-Energy Electron Irradiation in the Ba0.2K0.8Fe2As2 Superconductor

Yong Liu

Low-temperature variable-energy electron irradiation was used to induce non-magnetic disorder in a single crystal of a hole-doped iron-based superconductor, Ba1-xKxFe2As2, x = 0.80. To avoid systematic errors, the beam energy was adjusted non-consequently ...

The electron–hole bilayer tunnel FET

Mihai Adrian Ionescu, Luca De Michielis, Livio Lattanzio

We propose a novel tunnel field-effect transistor (TFET) concept called the electron–hole bilayer TFET (EHBTFET). This device exploits the carrier tunneling through a bias-induced electron–hole bilayer in order to achieve improved switching and higher driv ...

Sawtooth control in ITER using ion cyclotron resonance heating

Olivier Sauter, Martin Jucker, Jonathan Graves

Numerical modelling of the effects of ion cyclotron resonance heating (ICRH) on the stability of the internal kink mode suggests that ICRH should be considered as an essential sawtooth control tool in ITER. Sawtooth control using ICRH is achieved by direct ...
