The alignment between institutions and technology in network industries

Matthias Finger, Nicolas Crettenand

Network industries, such as electricity, railways and air transport, are very complex technical, economic, and political systems in which the alignment between technology and institutions has a significant impact on performance. This alignment has been stu ...

Tensor network study of the Shastry-Sutherland model in zero magnetic field

Frédéric Mila

We simulate the Shastry-Sutherland model in two dimensions by means of infinite projected entangled-pair states (iPEPS)-a variational tensor network method where the accuracy can be systematically controlled by the so-called bond dimension. Besides the wel ...

Nonlinear plasmonics of metallic heptamers

Olivier Martin, Krishnan Thyagarajan, Simon Rivier

Second-harmonic generation (SHG) from centrosymmetric nanostructures originating from the breaking of inversion symmetry at their surfaces is a well-known phenomenon and is extensively used as a surface probe in nonlinear optical microscopy. In recent year ...

Like a Bolt from the Blue: Phthalocyanines in Biomedical Optics

Hubert van den Bergh

The purpose of this review is to compile preclinical and clinical results on phthalocyanines (Pcs) as photosensitizers (PS) for Photodynamic Therapy (PDT) and contrast agents for fluorescence imaging. Indeed, Pcs are excellent candidates in these fields du ...

Nonlinear Correlation Spectroscopy (NLCS)

Theo Lasser, Marcel Leutenegger, Iwan Märki, Jean-Pierre Wolf, Noelia Laura Bocchio, Luigi Bonacina, Stefan Geissbuehler

We present a novel concept for optical spectroscopy called nonlinear correlation spectroscopy (NLCS). NLCS analyses coherent field fluctuations of the second and third harmonic light generated by diffusing nanoparticles. Particles based on noncentrosymmetr ...

Holographic second harmonic generation (SHG) microscopy

Christian Depeursinge, Pierre Marquet, Etienne Shaffer

The coherent nature of second harmonic generation (SHG) makes possible retrieval of both its amplitude and its phase, by use of a proper phase-sensitive imaging technique such as digital holographic SHG microscopy. In addition to retrieving both amplitude ...

Holographic Second Harmonic Generation Microscopy

Etienne Shaffer

This dissertation is dedicated to the application of digital holography methods to second harmonic generation microscopy, and to the development of the resulting imaging technique: holographic second harmonic generation microscopy. Second harmonic generati ...

Second harmonic phase microscopy of collagen fibers

Christian Depeursinge, Pierre Marquet, Etienne Shaffer

In the past decade, quantitative phase imaging gave a new dimension to optical microscopy, and the recent extension of digital holography techniques to nonlinear microscopy appears very promising, for the phase of nonlinear signal provides additional infor ...
