We develop the theory of the collective modes in these superconductors and discuss associated dissipation at microwave frequencies. We obtain the collective mode spectra dependence on the disorder level and conclude that collective modes become relevant source of dissipation and noise in the far vicinity of SIT.

Varying the strength of the center leads to a transition between two competing ground states with charges differing by (plus or minus) one. The hallmark of the transition scenario is a splitting of the number density distortion into a half-integer core and a large halo carrying the complementary charge plus/minus 1/2. The sign of the halo charge changes across the transition. The radius of the halo diverges on the approach to the critical strength of the center. ICTP ICTP pio@ictp.it 19 Oct 2017

Europe/Rome 2017-09-25 08:00:00 2017-09-29 22:00:00 Foundations and Applications of Nanomechanics | (smr 3177) The study of nanomechanical systems has evolved into a substantial and growing field of research. The interest in nanomechanical systems is fueled by their applicability to a wide range of problems: In addition to the ability to use these solid-state systems to investigate fundamental quantum physics and to target the frontiers of quantum mechanics, these systems also have applications in classical and quantum information technology and as ultrasensitive detectors of mass, displacement, acceleration, force or spin. As a result, research directions such as cavity optomechanics and nanoelectromechanics today attract a significant number of researchers from around the world. By their nature, nanomechanical systems are interdisciplinary, since they can couple to electrical circuits or optical cavities, and have potential applications in nano- and optomechanical technologies.   This workshop will highlight recent experimental and theoretical breakthroughs at the forefront of international research, and bring together international experts from the various fields of nanomechancs. Research Talks on: • Optomechanics; • Nanoelectromechanics; • Nanomechanical arrays; • Sensing; • Photonic crystals for optomechanics; • Diamond nanomechanics; • Nanotubes and graphene for nanomechanics; • surface-acoustic waves; • Coupling to superconducting circuits; • Microwave-to-optics conversion; • Quantum effects; • Foundational questions; • Entanglement; • and others Speakers: Adrian Bachtold, ICFO Barcelona Miles Blencowe, Dartmouth University Warwick Bowen, University of Queensland Tal Carmon, Technion Eddy Collin, Institut NÉEL CNRS Per Delsing, Chalmers Rosario Fazio, ICTP Trieste Simon Gröblacher, TU Delft Ania Jayich, UC Santa Barbara Hubert Krenner, University of Augsburg Peter Leek, Oxford University Niels Loerch, Basel University Francesco Marin, University of Florence Andreas Nunnenkamp, Cambridge University Vittorio Peano, University of Malta Martino Poggio, Basel University Cindy Regal, JILA Boulder Amir Safavi-Naeini, Stanford University Albert Schliesser, Niels Bohr Institute Copenhagen Signe Seidelin, University of Grenoble Philipp Treutlein, University of Basel Mukund Vengalattore, Cornell University David Vitali, University of Camerino Andre Xuereb, University of Malta Yun-Feng Xiao, Peking University For the 1st week Advanced School on Foundations and Applications of Nanomechanics 18 - 22 September 2017, go to link: http://indico.ictp.it/event/7991/ For the ICTP Colloqium, Prof. Florian Marquardt -  Light and Motion at the Nanoscale-  on Wed 27 Sept 2017 at 16:30 Leonardo Building - Budinich Lecture Hall, go to link: http://indico.ictp.it/event/8288 ICTP ICTP pio@ictp.it 25 Sep 2017 - 29 Sep 2017

Europe/Rome 2017-11-20 07:00:00 2017-12-02 21:00:00 Laboratory and Synchrotron X-ray Crystallography: Applications to Emerging Countries | (smr 3163) Crystallography is an interdisciplinary science that finds application in technological areas of strategic importance for emerging countries, such as cement, mining, electronic and pharmaceutical research. Special emphasis will be placed on the role of advanced synchrotron light sources. Crystallography enables to access the inner properties of matter and accurate atomic structures of molecules, materials, proteins and any kind of compound; without the knowledge of the structure, the functionality of a given material cannot be understood and therefore improved. Mining and cement companies use crystallography for quality and purity control and for research aimed at developing novel materials; the pharmaceutical industry uses crystallography to identify the correct polymorph and understanding the functionality of new medicines. Today synchrotron light sources complement laboratory X-ray equipment and allow access to unprecedented capabilities. Students will be encouraged to test their understanding on crystallography using single crystal and powder portable diffractometers, which will be installed on site for at least the duration of the school. Topics: •    X-ray and neutron diffraction physics •    powder and single-crystal methods •    physical properties of crystals •    symmetry and space groups •    structural refinement •    crystallographic databases •    applications to cement, mining, electronic and pharmaceutical industries •    nano-crystallography •    bio-crystallography •    quasicrystals •    synchrotron light sources Co-sponsored by: International Union of Crystallography; International Union of Pure and Applied Physics; Lightsources for Africa, the Americas and Middle East Project; ALBA Synchrotron; IUCr-UNESCO OpenLab.
