Accordingly, electrostatic (charge) gating is routinely used to affect and control the Coulomb electrostatics and quantum interference in modern nanodevices. Besides their charge, another (quantum mechanical) property of electrons — their spin — is at the heart of modern spintronics, a term implying that a number of magnetic and electrical properties of small systems are simultaneously harvested for device applications. In this presentation the possibility to achieve “spin gating” of mesoscopic devices [1], i.e. the possibility of an external spin control of the electronic properties of nanodevices is discussed. Rather than the Coulomb interaction, which is responsible for electric charge gating, we consider spin gating resulting from the Rashba type of electronic spin-orbit coupling. We show that electric weak links in the form of a nanowire that can be bent gives rise to a possibility for a mechanical control of the spin gating effect, since bending the nanowire affects the trajectory of the electron and therefore the spin-orbit interaction. Mechanically and microwave activated spin currents and superconducting currents in non-superconducting [2] and superconducting [3] devices will be discussed as examples of such a spin-mechanical manipulation. 1.

Namely, a suspended nanowire which is coupled to two oppositely polarized half-metals and subjected to a nonuniform magnetic field. It will be shown that in such system a temperature drop between the leads can significantly affect the dynamics of a mechanical degree of freedom. In particular, it is demonstrated that, under certain conditions, the stationary distribution of the mechanical subsystem has a Boltzmann form with an effective temperature, which is lower than the temperature of the “cold” lead; this seems rather counterintuitive. We also find that a change in the direction of the temperature gradient can result in the generation of mechanical vibrations rather than the heating of the mechanical subsystem. Therefore, the system resembles a nanoelectromechanical heat engine. We derive a criterion for the mechanical instability and estimate the amplitude of the resulting self-sustained oscillations. 1.

Europe/Rome 2017-09-18 08:00:00 2017-09-22 22:00:00 Advanced School on Foundations and Applications of Nanomechanics | (smr 3147) This school introduces the science of nanomechanical systems, a flourishing field of research. Nanomechanical systems are of interest both for their potential in terms of fundamental quantum physics as well as for applications in sensitive measurements, quantum information, and other areas. This Advanced School will recapitulate the foundations of nanomechanical systems and introduce the key concepts behind nano- and optomechanical technologies. The breadth of the field will be covered in six series of lectures delivered by internationally renowned experts. The pedagogical part of the school will be complemented by a series of about 20 invited presentations of state-of-the-art research. A crucial part of the school, in addition to the lectures and talks, will be the active contribution of the participants, which will be encouraged and fostered by several means: During the first week of the school, designated timeslots for tutorial classes will enable students to practice their skills in analytical as well as numerical methods, and will include problem solving and presentation of scientific results. The participants will work in small teams on research-type mini-projects. Lecturers: Yaroslav M.

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 Aashish Clerk, McGill University Eddy Collin, Institut NÉEL CNRS Per Delsing, Chalmers Rosario Fazio, ICTP Trieste Simon Gröblacher, TU Delft Shahal Ilani, Weizmann Institute Ania Jayich, UC Santa Barbara Hubert Krenner, University of Augsburg Peter Leek, Oxford 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 Gary Steele, TU Delft Philipp Treutlein, University of Basel Mukund Vengalattore, Cornell University David Vitali, University of Camerino Wolfgang Wernsdorfer, Karlsruhe Institute of Technology 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/ ICTP ICTP pio@ictp.it 25 Sep 2017 - 29 Sep 2017
