Simulation of plasma turbulence in the periphery of diverted tokamak by using the GBS code

Paolo Ricci, Paola Paruta, Fabio Riva, Christoph Wersal, Baptiste Jimmy Frei, Carrie Fiona Beadle

We report on the implementation of diverted magnetic equilibria in GBS and on first simulations in this geometry. GBS is a simulation code used to evolve plasma turbulence in the tokamak periphery by solving the drift-reduced Braginskii's equations. The mo ...

Heat kernel methods for Lifshitz theories

Diego Blas Temino, Mario Herrero Valea

We study the one-loop covariant effective action of Lifshitz theories using the heat kernel technique. The characteristic feature of Lifshitz theories is an anisotropic scaling between space and time. This is enforced by the existence of a preferred foliat ...

Multiplicity Of Solutions For Linear Partial Differential Equations Using (Generalized) Energy Operators

Jean-Philippe Lucien Montillet

Families of energy operators and generalized energy operators have recently been introduced in the definition of the solutions of linear Partial Differential Equations (PDEs) with a particular application to the wave equation [ 15]. To do so, the author ha ...

Corrugated tube protocol for autogenous shrinkage measurements: review and statistical assessment

Karen Scrivener, Zhangli Hu, Pietro Lura

Among different methods of measuring early age autogenous deformation of cementitious materials, the corrugated tube method described in the ASTMC1698-09 standard is one of the most commonly used. Despite the standardization and the common application of t ...

Evolution of the Valley Position in Bulk Transition-Metal Chalcogenides and Their Monolayer Limit

Dumitru Dumcenco, Yi Zhang, Bo Zhou, Zahid Hussain, Gang Xu, Kai Yan

Layered transition metal chalcogenides with large spin orbit coupling have recently sparked much interest due to their potential applications for electronic, optoelectronic, spintronics, and valleytronics. However, most current understanding of the electro ...

Numerical characterization of bump formation in the runaway electron tail

Joan Decker

Runaway electrons are generated in a magnetized plasma when the parallel electric field exceeds a critical value. For such electrons with energies typically reaching tens of MeV, the Abrahamâ Lorentzâ Dirac (ALD) radiation force, in reaction to the synch ...

Just-In-Time Data Virtualization: Lightweight Data Management with ViDa

Anastasia Ailamaki, Thomas Heinis, Miguel Sérgio De Oliveira Branco, Manolis Karpathiotakis, Ioannis Alagiannis

As the size of data and its heterogeneity increase, traditional database system architecture becomes an obstacle to data analysis. Integrating and ingesting (loading) data into databases is quickly becoming a bottleneck in face of massive data as well as i ...

Smooth Scan: Statistics-Oblivious Access Paths

Anastasia Ailamaki, Renata Borovica-Gajic

Query optimizers depend heavily on statistics representing column distributions to create efficient query plans. In many cases, though, statistics are outdated or non-existent, and the process of refreshing statistics is very expensive, especially for ad-h ...

Momentum-Resolved Spin Dynamics of Bulk and Surface Excited States in the Topological Insulator Bi2Se3

Marco Grioni, Helmuth Berger, Philippe Bugnon, Alberto Crepaldi

The prospect of optically inducing and controlling a spin-polarized current in spintronic devices has generated wide interest in the out-of-equilibrium electronic and spin structure of topological insulators. In this Letter we show that only measuring the ...

Nonexistence of smooth solutions for a full viscous isentropic liquid crystal system in three dimensions

Tudor Ratiu

We prove that the smooth solutions to the Cauchy problem for a full isentropic three-dimensional liquid crystal nematodynamic equations with conserved mass, linear momentum, and dissipating total energy, can lose classical smoothness within a finite time. ...
