Bilayer splitting and wave functions symmetry in Sr3Ir2O7
Henrik Moodysson Rønnow, Marco Grioni, Johan Juul Chang, Luca Moreschini, Simon Karl Moser, Bastien Dalla Piazza
The influence of dimensionality on the electronic properties of layered perovskite materials remains an outstanding issue. We address it here for Sr3Ir2O7, the bilayer compound of the iridate Srn+1IrnO3n+1 series. By angle-resolved photoemission spectrosco ...
Amer Physical Soc2014Command-line cellular electrophysiology for conventional and real-time closed-loop experiments
Background: Current software tools for electrophysiological experiments are limited in flexibility and rarely offer adequate support for advanced techniques such as dynamic clamp and hybrid experiments, which are therefore limited to laboratories with a si ...
Elsevier Science Bv2014Periodic and Quasi-Periodic Graphene-Based Reconfigurable Surfaces
We present recent results related to the modelling, design, and application of graphene surfaces. Mono and multilayer graphene surfaces are patterned in a periodic or quasi-periodic manner to tailor their electromagnetic response in terms of magnitude, pha ...
Ieee2013Power requirements for electron cyclotron current drive and ion cyclotron resonance heating for sawtooth control in ITER
Olivier Sauter, Stefano Coda, Timothy Goodman, Jonathan Graves, Costanza Zucca, Martin Jucker, Otto Asunta
13 MW of electron cyclotron current drive (ECCD) power deposited inside the q = 1 surface is likely to reduce the sawtooth period in ITER baseline scenario below the level empirically predicted to trigger neoclassical tearing modes (NTMs). However, since t ...
IOP2013Control approaches for robotic knee exoskeleton and their effects on human motion
In this paper we compare three noninvasive control methods for a robotic knee exoskeleton and asses their kinematic influences on the repetitive squatting motions of able-bodied human subjects. The motion of the subjects wearing the knee exoskeleton was al ...
2013Identification of Rational Transfer Functions from Sampled Data
Michaël Unser, John Paul Ward, Hagay Kirshner
We consider the task of estimating an operator from sampled data. The operator, which is described by a rational transfer function, is applied to continuous-time white noise and the resulting continuous-time process is sampled uniformly. The main question ...
SampTA2013A Natural Helical Crystal Lattice Model for Carbon Nanotubes
We propose a novel helical crystal lattice model for chiral and achiral carbon nanotubes (CNTs) where the unit cell and the helical crystal vector are defined in a unique and systematic manner for arbitrary CNTs. The small unit cell of this helical crystal ...
Amer Chemical Soc2013Real-Time Estimate of Velocity and Acceleration of Quasi-Periodic Signals Using Adaptive Oscillators
Estimation of the temporal derivatives of a noisy position signal is a ubiquitous problem in industrial and robotics engineering. Here, we propose a new approach to get velocity and acceleration estimates of cyclical/periodic signals near to steady-state r ...
Ieee-Inst Electrical Electronics Engineers Inc2013Magnetization States of All-Oxide Spin Valves Controlled by Charge-orbital Ordering of Coupled Ferromagnets
Charge-orbital ordering is commonly present in complex transition metal oxides and offers interesting opportunities for novel electronic devices. In this work, we demonstrate for the first time that the magnetization states of the spin valve can be directl ...
Nature Publishing Group2013Overview of recent and current research on the TCV tokamak
Through a diverse research programme, the Tokamak a Configuration Variable (TCV) addresses physics issues and develops tools for ITER and for the longer term goals of nuclear fusion, relying especially on its extreme plasma shaping and electron cyclotron r ...
