Two-Orbital Kondo Screening in a Self-Assembled Metal Organic Complex

Oleg Yazyev, Harald Brune, Stefano Rusponi, Marina Pivetta, Gabriel Albert Autes, Fabio Donati, Luca Gragnaniello, Giulia Elisabetta Pacchioni

Iron atoms adsorbed on a Cu(111) surface and buried under polyphenyl dicarbonitrile molecules exhibit strongly spatial anisotropic Kondo features with directionally dependent Kondo temperatures and line shapes, as evidenced by scanning tunneling spectrosco ...

All-optical flip-flop based on dynamic Brillouin gratings

Luc Thévenaz, Marcelo Alfonso Soto Hernandez, Andrey Denisov

One of the most essential building blocks in modem electronics is the flip-flop. A flip-flop operates bi-stably between two states, remaining at a given output level (high or low level) until a specific input control signal changes. For many years, photoni ...

Near optimal graphene terahertz non-reciprocal isolator

Juan Ramon Mosig, Mihai Adrian Ionescu, Julien Perruisseau-Carrier, Michele Tamagnone, Clara-Fausta Moldovan

Isolators, or optical diodes, are devices enabling unidirectional light propagation by using non-reciprocal optical materials, namely materials able to break Lorentz reciprocity. The realization of isolators at terahertz frequencies is a very important ope ...

Femtosecond laser direct-write waveplates based on stress-induced birefringence

Yves Bellouard, Christos Edouardos Athanasiou, Benjamin Wesley Mc Millen

The use of femtosecond lasers to introduce controlled stress states has recently been demonstrated in silica glass. We use this technique, in combination with chemical etching, to generate and control stress-induced birefringence over a well-defined region ...

Microwave-gated dynamic nuclear polarization

Geoffrey Bodenhausen, David Lyndon Emsley, Sami Jannin, Aurélien Bornet, Arthur César Pinon, Xiao Ji

Dissolution dynamic nuclear polarization (D-DNP) has become a method of choice to enhance signals in nuclear magnetic resonance (NMR). Recently, we have proposed to combine cross-polarization (CP) with D-DNP to provide high polarization P(C-13) in short bu ...

Brillouin dynamic gratings in optical fibres for distributed sensing and advanced optical signal processing

Andrey Denisov

This thesis presents results of a research on applications of Brillouin dynamic gratings - distributed reflectors that can be dynamically created in an optical fibre by two optical waves. A basic theory of stimulated Brillouin scattering (SBS) is introduce ...

Volume refractometry of liquids using stable optofluidic Fabry-Perot resonator with curved surfaces

This work reports a simple, miniaturized optical sensing module for liquid refractometry. It is based on a stable Fabry-Perot resonator consisting of two silicon cylindrical mirrors with a cylindrical lens in the core. The lens is formed by a capillary tub ...

Multi-band reflectarray antennas in Ku and THz frequency bands

Hamed Hasani

Printed reflectarrays are low-cost, low-profile high gain antennas demonstrating distinctive advantages over conventional parabolic reflectors and phased-arrays. The flat, low weight reflecting surface of a reflectarray makes it an attractive alternative w ...

Semiclassical evidence of columnar order in the fully frustrated transverse-field Ising model on the square lattice

Frédéric Mila, Tommaso Coletta

We investigate the zero-temperature phase diagram of the fully frustrated transverse-field Ising model on the square lattice both in the classical limit and in the presence of quantum fluctuations. At the classical level (the limit of infinite spin S), we ...
