Single chip microsystems for electron spin resonance spectroscopy and inductive proximity sensing

Electron spin resonance spectroscopy is a non-invasive technique to explore paramagnetic systems. ESR spectrometers operate in a wide range of frequencies from 1 MHz to 1 THz, and at temperatures from 1000 K to mK. Boero's group pioneered a novel approach ...

Room-Temperature Exciton-Polariton-Driven Self-Phase Modulation in Planar Perovskite Waveguides

Mikhail Masharin, Nikita Glebov

Optical nonlinearities are crucial for advanced photonic technologies since they allow photons to be managed by photons. Exciton-polaritons resulting from strong light-matter coupling are hybrid in nature: they combine the small mass and high coherence of ...

Tuning Molecular Emission: Exploring Plasmonic Coupling Effects across High and Low Quantum Yields

Olivier Martin, Stavros Athanasiou

The interaction between molecules and plasmonic nanoparticles significantly influences molecular emission properties, offering opportunities to enhance fluorescence through the Purcell effect and strong coupling phenomena. While previous studies have focus ...

Mitigation of divertor edge localised mode power loading by impurity seeding

Olivier Claude Martin Février

One of the major challenges for the design of future thermonuclear reactors is the problem of power exhaust — the removal of heat fluxes deposited by plasma particles onto the plasma-facing components (PFCs) of the reactor wall. In order for the reactor to ...

Atomic layer deposition of Ni and Ni80Fe20 for tubular spin-wave nanocavities

Maria Carmen Giordano

Magnetic thin films and magnetic nanostructures have become essential components of modern technological applications. Modern branches of magnetisms focus on spin-charge coupling (spintronics) and the collective excitation of spin waves in magnetically ord ...

Negative ion characterization in a helicon plasma source for fusion neutral beams by cavity ring-down spectroscopy and Langmuir probe laser photodetachment

Ivo Furno, Alan Howling, Gennady Plyushchev, Philippe Frédérique Bruno Guittienne, Riccardo Agnello, Rémy Jacquier

Negative ions are characterized in the helicon plasma source resonant antenna ion device (RAID) at the Swiss plasma center by means of cavity ring-down spectroscopy (CRDS) and Langmuir probe (LP)-assisted laser photodetachment. A high density and axially h ...

Solvent fluctuations and nuclear quantum effects modulate the molecular hyperpolarizability of water

Michele Ceriotti, Sylvie Roke, David Mark Wilkins, Andrea Grisafi, Gabriele Tocci, Chung-Wen Liang

Second-harmonic scattering (SHS) experiments provide a unique approach to probe noncentrosymmetric environments in aqueous media, from bulk solutions to interfaces, living cells, and tissue. A central assumption made in analyzing SHS experiments is that ea ...

Cross polarization from H-1 to quadrupolar Li-6 nuclei for dissolution DNP

Geoffrey Bodenhausen, Sami Jannin, Aurélien Bornet, Jonas Milani, Basile Vuichoud, Angel Joaquin Perez Linde

Cross polarization from protons to quadrupolar Li-6 nuclei is combined with dynamic nuclear polarization of protons at 1.2 K and 6.7 T using TEMPOL as a polarizing agent followed by rapid dissolution. Compared to direct Li-6 DNP without cross-polarization, ...
