Emergence of synchronised and amplified oscillations in neuromorphic networks with long-range interactions

Daniel Maria Busiello, Samir Suweis

Neuromorphic networks can be described in terms of coarse-grained variables, where emergent sus-tained behaviours spontaneously arise if stochasticity is properly taken into account. For example it has been recently found that a directed linear chain of co ...

Transverse Noise, Decoherence, and Landau Damping in High-Energy Hadron Colliders

Sondre Vik Furuseth

High-energy hadron colliders are designed to generate particle collisions within specialized detectors. A higher number of collisions is achieved with high-quality beams of low transverse emittances, meaning a small transverse cross-section, and high inten ...

Ultra-Compact Ka-band Metamaterial Waveguide Filters, Fabricated by Lost-Wax Casting

Romain Christophe Rémy Fleury, Maliheh Khatibi Moghaddam

This paper proposes a novel technique for the design of miniaturized Ka-band filters based on locally resonant metamaterials (LRMs), which are fabricated monolithically using lost wax casting. We implement ultra-small metamaterial filters by exploiting a n ...

Reconfigurable Radiofrequency Photonic Filters Based on Soliton Microcombs

Tobias Kippenberg, Camille Sophie Brès, Junqiu Liu, Jijun He, Arslan Sajid Raja, Jianqi Hu

We demonstrate soliton based radiofrequency filters using a 104 GHz Si3N4 microresonator. The filter passband frequencies are widely reconfigured via inherent soliton states of perfect soliton crystals and two-soliton microcombs, without any external pulse ...

Reconfigurable radiofrequency filters based on versatile soliton microcombs

Tobias Kippenberg, Camille Sophie Brès, Junqiu Liu, Maxim Karpov, Jijun He, Arslan Sajid Raja, Jianqi Hu, Anton Lukashchuk

The rapidly maturing integrated Kerr microcombs show significant potential for microwave photonics. Yet, state-of-the-art microcomb-based radiofrequency filters have required programmable pulse shapers, which inevitably increase the system cost, footprint, ...

Single shot acquisition of spatially resolved spin wave dispersion relations using X-ray microscopy

Dirk Grundler

For understanding magnonic materials the fundamental characterization of their frequency response is essential. However, determining full dispersion relations and real space wavelength measurements are challenging and time-consuming tasks. We present an ap ...

Dynamic response of a compressible binary fluid mixture

Ignacio Pagonabarraga Mora

Binary fluids are present in a wide variety of systems at microscales, such as microfluidic devices containing drops, fluids with air bubbles trapped in them, and devices designed to mix fluids or to make two fluid substances react. Microfluidics devices a ...

Magnetic hyperthermia with epsilon-Fe(2)O(3)nanoparticles

Débora Bonvin

Biocompatibility restrictions have limited the use of magnetic nanoparticles for magnetic hyperthermia therapy to iron oxides, namely magnetite (Fe3O4) and maghemite (gamma-Fe2O3). However, there is yet another magnetic iron oxide phase that has not been c ...

Rectangular waveguides for applications using terahertz signals

Emile Jacques de Rijk, Alessandro Macor

A waveguide for transmitting signals at terahertz (THz) frequencies, wherein said waveguide comprises at least a matrix and an insert piece having a waveguide channel, wherein said piece is inserted in said matrix. ...
