Magnetoresistive RAM for error resilient XNOR-Nets
Michail Tzoufras, Marcin Gajek, Andrew Walker
We trained three Binarized Convolutional Neural Network architectures (LeNet-4, Network-In-Network, AlexNet) on a variety of datasets (MNIST, CIFAR-10, CIFAR-100, extended SVHN, Im…
Switching probability of all-perpendicular spin valve nanopillars
Michail Tzoufras
In all-perpendicular spin valve nanopillars the probability density of the free-layer magnetization is independent of the azimuthal angle and its evolution equation simplifies cons…
Beam loading in the nonlinear regime of plasma-based acceleration
M. Tzoufras, W. Lu, F. S. Tsung +6
A theory that describes how to load negative charge into a nonlinear, three-dimensional plasma wakefield is presented. In this regime, a laser or an electron beam blows out the pla…
One-to-one full scale simulations of laser wakefield acceleration using QuickPIC
J. Vieira, F. Fiuza, R. A. Fonseca +9
We use the quasi-static particle-in-cell code QuickPIC to perform full-scale, one-to-one LWFA numerical experiments, with parameters that closely follow current experimental condit…
Three-dimensional structure of the laser wakefield accelerator in the blowout regime
J. F. Vieira, S. F. Martins, F. Fiuza +9
Three-dimensional Particle-in-Cell (PIC) simulations with the code QuickPIC are used to illustrate the typical accelerating structures associated with the interaction of an intense…
Generating multi-GeV electron bunches using single stage laser wakefield acceleration in a 3D nonlinear regime
W. Lu, M. Tzoufras, C. Joshi +5
The extraordinary ability of space-charge waves in plasmas to accelerate charged particles at gradients that are orders of magnitude greater than in current accelerators has been w…
