Dual comb generation in a monochromatically driven crystalline microresonator

Tobias Kippenberg, Erwan Guillaume Albert Lucas, Wenle Weng

Recent works on Kerr frequency combs demonstrated the possibility to simultaneously generate multiple soliton states with different group velocities in a single microresonator, which could be beneficial for many applications utilizing dual-comb systems. In ...

Polychromatic Cherenkov Radiation Induced Group Velocity Symmetry Breaking in Counterpropagating Dissipative Kerr Solitons

Tobias Kippenberg, Erwan Guillaume Albert Lucas, Wenle Weng

High-order-dispersion-induced dispersive waves emitted by dissipative Kerr solitons are frequently observed in microresonator frequency comb generation. Also known as soliton Cherenkov radiation, this type of dispersive wave plays a critical role in comb s ...

Side emissions during EC injection for PDI studies in FTU tokamak

Cristian Galperti, Gabriele Grosso

The evidence of Parametric Decay Instabilities (PDI) excited by the ECH power injected in O-Mode has been explored in FTU Tokamak, using the Collective Thomson Scattering (CTS) diagnostic. The experiments show evidences to support the hypothesis of low-thr ...

Ultrabroadband 3D invisibility with fast-light cloaks

Hatice Altug, Dordaneh Etezadi, Kosmas Tsakmakidis, Ershad Mohammadi, Foziyeh Sohrabi

An invisibility cloak should completely hide an object from an observer, ideally across the visible spectrum and for all angles of incidence and polarizations of light, in three dimensions. However, until now, all such devices have been limited to either s ...

Tangential phase-contrast imaging for fluctuation measurements in JT–60SA: a conceptual study

Stefano Coda, Stephan Brunner, Kenji Tanaka, Aylwin Iantchenko

This contribution will present a feasibility study and conceptual design of a tangential phase-contrast imaging (PCI) diagnostic for the new JT60SA tokamak. PCI is a well-known technique for measuring density fluctuations. Tangential launching, combined wi ...

Evolution and decay of gravity wavefields in weak-rotating environments: a laboratory study

Hugo Nicolás Ulloa Sánchez

Gravity waves are prominent physical features that play a fundamental role in transport processes of stratified aquatic ecosystems. In a two-layer stratified basin, the equations of motion for the first vertical mode are equivalent to the linearised shallo ...

3D Boundary Element Simulation of Droplet Dynamics in Microchannels: How Droplets Squeeze Through Constrictions and Move in Electric Fields

Simon Sebastian Schütz

Flows of fluids with free surfaces show complex dynamical behavior. Examples include effects like capillary surface waves, topological transitions such as droplet breakup and coalescence, or pattern formation in wetting and de-wetting dynamics. These compl ...

Jetting from cavitation bubbles due to multiple shockwaves

Mohamed Farhat, Outi Supponen

We present experimental observations of microjets formed by cavitation microbubbles. An underwater electric discharge, applied beneath a flat free surface, produces a primary compression wave, which undergoes several phase inversions upon reflections from ...

Wave impact on oriented impervious buildings

Anton Schleiss, Michael Pfister, Davide Wüthrich, Claudia Ylla Arbos

Recent studies showed that a speciﬁc design can reduce the impact of water waves on structures, thus limiting the damages. Herein the impact of waves on buildings is addressed, pointing out the inﬂuence of orientation on the hydrodynamic process. ...

Experimental comparison of tsunami generated by viscoplastic and granular slides.

Zhenzhu Meng

Tsunami induced by subaerial landslides threatens coastal areas. The waves have mostly been studied in the laboratory using sliding blocks or granular media hitting a water body, but none of these materials makes it possible to understand how sliding mass’ ...
