Dr. Dmitriy Kostunin (Institute for Nuclear Physics, Karlsruhe Institute of Technology)

Abstract:

In the present talk I discuss the modern technique of ultra-high energy cosmic-ray detection by measuring the radio emission produced during the development of air-showers induced by these particles. One of the successful implementation of this technique is the Tunka-Rex (Tunka Radio Extension) experiment operating since 2012 in the frame of the Tunka Advanced Instrument for cosmic ray physics and Gamma Astronomy (TAIGA) located in Siberia nearby Lake Baikal. I discuss the radio detection of air-showers, the methods for reconstruction of primary energy and...

Marco Deluca (Materials Center Leoben Forschung GmbH)

Abstract: A-⁠ and B-⁠site substitution of barium titanate with homovalent or heterovalent dopants is at the basis of solid solutions that lately found increasing importance for dielectric, piezoelectric, energy storage and microwave applications. High dielectric permittivity—stable over a large temperature range—and large high-⁠field piezoelectric coefficients are typically sought-⁠for figures of merit. Yet, compositional tuning to attain specific properties has been largely based on macroscopic observations and very little is known about the fine material structure on the short range that is...

N. David Mermin (Laboratory of Atomic & Solid Physics Cornell University, Ithaca, USA)

N. David Mermin received his undergraduate degree in Mathematics at Harvard University in 1956, and his Ph.D. in Physics at Harvard in 1961. He was a postdoctoral fellow with Rudolf Peierls and later with Walter Kohn. Since 1964 he has been on the faculty of Cornell University, where he was Director of the Laboratory of Atomic and Solid State Physics from 1984 to 1990. Since 2006, he has been the Horace White Professor of Physics Emeritus. He is the author (with Neil W. Ashcroft) of the well-known textbook Solid State Physics. He has also written four books about science for the general...

Larisa Panina (National University of Science and Technology MISIS, Moscow)

Magnetic bio-detection constitutes a large area of research driven by its potential to provide versatile diagnostic tools. Specific sensing technology is used depending on the applications which can be subdivided in two main groups: measuring a magnetic field from living organs and detecting magnetically labelled bio substances. The human body has some magnetic sensitivity, however small, being paramagnetic or diamagnetic. In addition, there is a further source of a magnetic field due to the neural activity which involves the movement of electric charges and gives rise to magnetic fields. In...
