Dynamical Defects in Rotating Magnetic Skyrmion Lattices

The chiral magnet Cu2OSeO3 hosts a Skyrmion lattice that may be equivalently described as a superposition of plane waves or a lattice of particlelike topological objects. A thermal gradient may break up the Skyrmion lattice and induce rotating domains, rai ...

Clocking the onset of bilayer coherence in a high-Tc cuprate

Fabrizio Carbone, Frank van Mourik, Christopher Alexander Arrell, Edoardo Baldini, Andreas Helmut Christian Mann, Dragan Mihailovic

In cuprates, a precursor state of superconductivity is speculated to exist above the critical temperature T-c. Here we show via a combination of far-infrared ellipsometry and ultrafast broadband optical spectroscopy that signatures of such a state can be o ...

Resonance between heat-carrying electrons and Langmuir waves in inertial confinement fusion plasmas

Stephan Brunner

In ignition scale hot plasmas, temperature gradients and thermal transport modify electron distributions in a velocity range resonant with Langmuir waves typical of those produced by stimulated Raman scattering. We examine the resultant changes to the Land ...

Solutions for thermally mismatched brazing operations for ceramic tokamak magnetic sensor

Duccio Testa, Peter Ryser, Matthieu Toussaint, Thomas Maeder, Caroline Jacq, Philipp Windischhofer, Xinyue Jiang

To monitor high-frequency fluctuations of the equilibrium magnetic field in tokamaks, a 3D magnetic sensor has been developed. The sensor, which is positioned inside the vacuum vessel behind the protective tiles of the tokamak and is exposed to potential t ...

On the establishment of thermal diffusion in binary Lennard-Jones liquids

Sara Bonella, Mauro Ferrario

The establishment of thermal diffusion in an Ar-Kr Lennard-Jones mixture is investigated via dynamical non equilibrium molecular dynamics [G. Ciccotti, G. Jacucci, Phys. Rev. Lett. 35, 789 (1975)]. We observe, in particular, the evolution of the density an ...

Effect of Heat Current on Magnetization Dynamics in Magnetic Insulators and Nanostructures

Francesco Antonio Vetrò

The term "spin caloritronics" defines a novel branch of spintronics that focuses on the interplay between electron spins with heat currents. In the frame of this research area, this thesis is aimed at investigating the effect of a heat current on magnetiza ...

Stable Atmospheric Boundary-Layer Flows over a Steep, Alpine Slope: Observations, Theory and Multi-Scale Transport Dynamics

Marc Parlange, Chad Higgins, Holly Jayne Oldroyd, Eric Richard Pardyjak

Katabatic flows are high density air flows traversing down a slope under the action of a gravitational force. These flows can be exploited for wind energy and are gaining importance in predicting scalar transport (e.g. pollutants, water vapor, CO2 drainage ...

Prediction of quenching-induced stress distribution in 7XXX aluminium alloy thick plates using Gleeble interrupted quench tests

Jean-Marie Drezet, Nicolas Paul Henry Chobaut, Patrick Schloth, Denis Carron

In the fabrication of heat treatable aluminum parts for the aeronautic industry, quenching is a key step to obtain the required mechanical characteristics after aging. For thick plates, thermal gradients cause non-homogeneous plastic strain resulting in re ...

A Semi-Analytical Thermal Modeling Framework for Liquid-Cooled ICs

David Atienza Alonso, Arvind Raj Mahankali Sridhar, Mohamed Mostafa Sabry Aly

While possessing the potential to replace conventional air-cooled heat sinks, inter-tier microchannel liquid cooling of 3D ICs also creates the problem of increased thermal gradients from the fluid inlet to outlet ports [1, 2]. These cooling-induced therma ...

Migration of volatile organic contaminations (VOCs) through a deforming clay liner

David Andrew Barry

A fully coupled thermal–hydraulic–mechanical–chemical (THMC) model was proposed to describe the migration of volatile organic contaminations (VOCs) in unsaturated landfill liners. The vertical soil stress, capillary pressure, air pressure, temperature incr ...
