Quantum Critical Regime in a Quadratically Driven Nonlinear Photonic Lattice

Vincenzo Savona, Riccardo Rota, Fabrizio Minganti, Cristiano Ciuti

We study an array of coupled optical cavities in the presence of two-photon driving and dissipation. The system displays a critical behavior similar to that of a quantum Ising model at finite temperature. Using the corner-space renormalization method, we c ...

Non-destructive piezoelectric characterisation of Sc doped aluminium nitride thin films at wafer level

Paul Muralt, Stefan Mertin, Clemens Benedict Nyffeler, Andrea Mazzalai

Scandium doped aluminium nitride (ScAlN) gained much attention during last years, since its piezoelectric response is much enlarged as compared to pure AlN films. Above 30% Sc the films are of high interest for piezoMEMS sensing and actuation, ultrasound g ...

Improved mechanical dispersion or use of coupling agents? Advantages and disadvantages for the properties of fluoropolymer/ceramic composites

Sara Dalle Vacche, Véronique Michaud, Yves Leterrier, Dragan Damjanovic

The aim of this work is to investigate the influence of interfacial chemistry on the properties of fluoropolymer composites, independent of effects derived from changes in morphology, in particular particle dispersion state. A comparative study of solvent ...

A second harmonic based resonance characterization method for MEMS electrostatic resonators

Ozge Zorlu, Mustafa Kangül, Furkan Gökçe, Eren Aydin

This paper presents a novel read-out approach both for eliminating parasitic feedthrough current and for enhancing the quality-factor (Q) of the resonating system at the same time. A new resonance characterization method based on sensing second harmonic co ...

Investigation of RF Nb-Ti PF 1&6 Coils Conductor Performances in the SULTAN Test Facility

Pierluigi Bruzzone, Boris Stepanov

This paper summarizes the work on the manufacturing and testing of conductor samples for ITER poloidal field 1&6 coils. The work was carried out by the IO and multiple institutions in the EU, Switzerland and Russia. Five samples were manufactured and teste ...

Vectorial scanning force microscopy using a nanowire sensor

Anna Fontcuberta i Morral, Gözde Tütüncüoglu, Nicola Rossi

Self-assembled nanowire (NW) crystals can be grown into nearly defect-free nanomechanical resonators with exceptional properties, including small motional mass, high resonant frequency and low dissipation. Furthermore, by virtue of slight asymmetries in ge ...

On the Efficiency Alteration Mechanisms Due to Cavitation in Kaplan Turbines

François Avellan, Sebastián Camilo Leguizamón Sarmiento

A transport-equation-based homogeneous cavitation model previously assessed and validated against experimental data is used to investigate and explain the efficiency alteration mechanisms in Kaplan turbines. On the one hand, it is shown that the efficiency ...

Performance of ITER Correction Busbar Conductor Samples CBCN2 and CBCN3

Pierluigi Bruzzone, Kamil Sedlák, Boris Stepanov, Fang Liu, Bo Liu

The correction busbar (CB) conductors for the ITER project are being produced in China. The second China CB conductor sample (CBCN2, Phase II of conductor testing) and the third CB conductor sample (CBCN3, Phase III testing) were made of the WST NbTi stran ...
