| 11:00 - 13:00 Theoretical Neuroscience Journal Club Robust associative learning is sufficient to explain the structural and dynamical properties of local cortical circuits School COGNITIVE SCIENCES Venue: School of Cognitive Sciences, Institute for Research in Fundamental Sciences (IPM), Opposite the ARAJ, Artesh Highway, Tehran, Iran Abstract: >> schedule >> Poster of this session ... 14:00 - 15:00 Weekly Seminar Condensed Matter and Statistical Physics Group Light scattering from clusters of particles using multipole fields method School PHYSICS Venue: Seminar Room (classroom A), Farmanieh Building, IPM ... 14:00 - 15:00 Weekly Seminar Light scattering from clusters of particles using multipole fields method School NANO SCIENCES Light scattering from clusters of particles using multipole fields method Abstract: Optical properties of aggregates distinct them from their bulk counterparts. Till now, light scattering from a populous cluster is mostly studied using the dipole approximation. In this study, we use multipole fields method to study the influence of arrangement of particles on the light absorption and scattering of a cluster. We pay attention to various nanoparticles, including charged, hollow, anisotropic, and metallic particles. We calculate electric and magnetic field enhancement in the gaps of dimers and trimers of hollo ... 15:00 - 16:00 Weekly Seminar Non-relativistic effective field theories and its applications to cosmology School PARTICLES AND ACCELERATORS Abstract: Field theories in the non-relativistic limit are of interest in a wide range of physical situations. In particular - in the context of cosmology - it is an appropriate tool for studying the axion dark matter and superradiant instabilities. In this talk, I will introduce a systematic and self consistent way of taking the non-relativistic limit of a field theory from which one can read off the leading order theory for the non-relativistic system as well as its relativistic corrections. Time permitting, I will discuss possible applications of the formalism to cosmology. Larak Seminar Room |
