Quantum Algorithmic Readout in Multi-Ion Clocks [PDF]

, 2016
Optical clocks based on ensembles of trapped ions offer the perspective of record frequency uncertainty with good short-term stability. Most suitable atomic species lack closed transitions for fast detection such that the clock signal has to be read out ...

Experiments in high-performance JET plasmas in preparation of second harmonic ICRF heating of tritium in ITER

Nuclear Fusion, 2023
The reference ion cyclotron resonance frequency (ICRF) heating schemes for ITER deuterium–tritium (D-T) plasmas at the full magnetic field of 5.3 T are second harmonic heating of T and ^3 He minority heating.

First principles of modelling the stabilization of microturbulence by fast ions [PDF]

, 2018
The observation that fast ions stabilize ion-temperature-gradient-driven microturbulence has profound implications for future fusion reactors. It is also important in optimizing the performance of present-day devices.

Fast Lithium Ion Conduction in Lithium Phosphidoaluminates [PDF]

Angewandte Chemie International Edition, 2020
AbstractSolid electrolyte materials are crucial for the development of high‐energy‐density all‐solid‐state batteries (ASSB) using a nonflammable electrolyte. In order to retain a low lithium‐ion transfer resistance, fast lithium ion conducting solid electrolytes are required.

Sympathetic and swap cooling of trapped ions by cold atoms in a MOT [PDF]

, 2011
A mixed system of cooled and trapped, ions and atoms, paves the way for ion assisted cold chemistry and novel many body studies. Due to the different individual trapping mechanisms, trapped atoms are significantly colder than trapped ions, therefore in ...

Fast-ion redistribution and loss due to edge perturbations in the ASDEX Upgrade, DIII-D and KSTAR tokamaks [PDF]

, 2013
The impact of edge localized modes (ELMs) and externally applied resonant and non-resonant magnetic perturbations (MPs) on fast-ion confinement/transport have been investigated in the ASDEX Upgrade (AUG), DIII-D and KSTAR tokamaks.

Scalable quantum computation with fast gates in two-dimensional microtrap arrays of trapped ions [PDF]

, 2020
We theoretically investigate the use of fast pulsed two-qubit gates for trapped ion quantum computing in a two-dimensional microtrap architecture. In one dimension, such fast gates are optimal when employed between nearest neighbours, and we examine the ...

Fast Ion Conductors

Journal of the American Ceramic Society, 1979
The results of transmission electron microscopy and their relation to some practical aspects of Na β‐ nd β‐alumina solid electrolytes are reviewed. Grain and grain‐boundary morphology, crystallographic defects, nonstoichiometry, and second‐phase formation are discussed.
