UV-extending ghost inflation

We present a setup that provides a partial UV-completion of the ghost inflation model up to a scale which can be almost as high as the Planck mass. This is achieved by coupling the inflaton to the Lorentz-violating sector described by the Einstein-aether t ...

Gutzwiller electronic structure calculations applied to transition metals: Kinetic energy gain with ferromagnetic order in bcc Fe

Giovanni Borghi

The Gutzwiller projector technique has long been known as a method to include correlations in electronic structure calculations. We describe a model implementation for a Gutzwiller + LDA calculation in a localized-orbital restricted basis framework, emphas ...

Effects of High Angular Momentum on the Unimolecular Dissociation of CD2CD2OH: Theory and Comparisons with Experiment

Michele Ceriotti

This paper explores the dynamics of a highly rotationally and vibrationally excited radical, CD2CD2OH. The radical is produced from the 193 nm photodissociation of 2-bromoethanol-d(4), so it is imparted with high angular momentum and high vibrational energ ...

Linear stability analysis of wind turbine wakes performed on wind tunnel measurements

Fernando Porté Agel, François Gallaire, Giacomo Valerio Iungo, Francesco Viola

Wind tunnel measurements were performed for the wake produced by a three-bladed wind turbine immersed in uniform flow. These tests show the presence of a vorticity structure in the near-wake region mainly oriented along the streamwise direction, which is d ...

On the experimental determination of the efficiency of piezoelectric impact-type energy harvesters using a rotational flywheel

Nico de Rooij, Danick Briand, Simon Nessim Henein, Pattanaphong Janphuang, Robert Andrew Lockhart

This paper demonstrates a novel methodology using a rotational flywheel to determine the energy conversion efficiency of the impact based piezoelectric energy harvesters. The influence of the impact speed and additional proof mass on the efficiency is pres ...

Dynamic stall on a fully equipped helicopter model

Karen Ann J Mulleners, Kolja Kindler

Three-dimensional dynamic stall was observed on the rotor of a fully equipped subscale helicopter model in a wind tunnel. Results of stereoscopic particle image velocimetry measurements on the retreating blade clearly revealed the large-scale dynamic stall ...

Hub vortex helical instability as the origin of wake meandering in the lee of a model wind-turbine

Fernando Porté Agel, François Gallaire, Giacomo Valerio Iungo, Francesco Viola

Wind tunnel measurements were performed for the wake produced by a three-bladed wind turbine immersed in uniform flow. These tests show the presence of a vorticity structure in the near wake region mainly oriented along the streamwise direction, which is d ...

Efficient First-Principles Calculation of the Quantum Kinetic Energy and Momentum Distribution of Nuclei

Michele Ceriotti

Light nuclei at room temperature and below exhibit a kinetic energy which significantly deviates from the predictions of classical statistical mechanics. This quantum kinetic energy is responsible for a wide variety of isotope effects of interest in fields ...

Estimating the non-linear dynamics of free-flying objects

Aude Billard, Seungsu Kim

This paper develops a model-free method to estimate the dynamics of free-flying objects. We take a realistic perspective to the problem and investigate tracking accurately and very rapidly the trajectory and orientation of an object so as to catch it in fl ...

One- and two-dimensional UVP velocity sampling in a cuboidal basin subject to in- and outflow sequences

Anton Schleiss, Giovanni De Cesare, Michael Müller

In the framework of an experimental study on the influence of in- and outflow sequences on flow patterns and suspended sediment behavior in reservoirs, flow fields and inflowing jet were sampled by Ultrasonic Velocity Profilers (UVP). The laboratory set-up ...
