Correlated Decay of Triplet Excitations in the Shastry-Sutherland Compound SrCu2(BO3)(2)

Henrik Moodysson Rønnow, Joël Mesot

The temperature dependence of the gapped triplet excitations (triplons) in the 2D Shastry-Sutherland quantum magnet SrCu2(BO3)(2) is studied by means of inelastic neutron scattering. The excitation amplitude rapidly decreases as a function of temperature, ...

Cryogenic single-chip electron spin resonance detector

Stefano Alberti, László Forró, Giovanni Boero, Andrzej Sienkiewicz, Jens Anders, Gabriele Gualco

We report on the design and characterization of a single-chip electron spin resonance detector, operating at a frequency of about 20 GHz and in a temperature range extending at least from 300 K down to 4 K. The detector consists of an LC oscillator formed ...

Time-Delayed Interactions in Networks of Self-Adapting Hopf Oscillators

Max-Olivier Hongler, Julio Rodriguez, Philippe Blanchard

A network of coupled limit cycle oscillators with delayed interactions is considered. The parameters characterizing the oscillator’s frequency and limit cycle are allowed to self-adapt. Adaptation is due to time-delayed state variables thatmutually interac ...

An Artificial Muscle Ring Oscillator

Dielectric elastomer artificialmuscles have great potential for the creation of novel pumps, motors, and circuitry. Control of these devices requires an oscillator, either as a driver or clock circuit, which is typically provided as part of bulky, rigid, a ...

Topological Measure Locating the Effective Crossover between Segregation and Integration in a Modular Network

Ali Ajdari Rad

We introduce an easily computable topological measure which locates the effective crossover between segregation and integration in a modular network. Segregation corresponds to the degree of network modularity, while integration is expressed in terms of th ...

Roombots: Reconfigurable Robots for Adaptive Furniture

Auke Ijspeert, Pierre Dillenbourg, Aude Billard, Alexander Spröwitz, Rico Möckel, Soha Pouya, Jesse van den Kieboom, Stéphane Bonardi

Imagine a world in which our furniture moves around like legged robots, interacts with us, and changes shape and function during the day according to our needs. This is the long term vision we have in the Roombots project. To work towards this dream, we ar ...

Single-chip detector for electron spin resonance spectroscopy

Giovanni Boero

We have realized an innovative integrated detector for electron spin resonance spectroscopy. The microsystem, consisting of an LC oscillator, a mixer, and a frequency division module, is integrated onto a single silicon chip using a conventional complement ...

Frequency analysis with coupled nonlinear oscillators

Auke Ijspeert, Ludovic Righetti, Jonas Buchli

We present a method to obtain the frequency spectrum of a signal with a nonlinear dynamical system. The dynamical system is composed of a pool of adaptive frequency oscillators with negative mean-field coupling. For the frequency analysis, the synchronizat ...
