| 11:00 - 12:00 Quantum information biweekly journal club Thermodynamical cost of some interpretations of quantum theory School NANO SCIENCES Thermodynamical cost of some interpretations of quantum theory The interpretation of quantum theory is one of the longest-standing debates in physics. Type I interpretations see quantum probabilities as determined by intrinsic properties of the observed system. Type II see them as relational experiences between an observer and the system. It is usually believed that a decision between these two options cannot be made simply on purely physical grounds but requires an act of metaphysical judgment. Here we show that, under some assumptions, the problem is decidable using thermodynamics. We prove that type I interpretations are ... 14:00 - 15:00 Weekly Seminar Delocalization, geometry, and optimality in purple bacterial light harvesting School NANO SCIENCES Delocalization, geometry, and optimality in purple bacterial light harvesting Photosynthetic organisms harvest light using antenna complexes containing many chlorophyll molecules. Despite the wide variety of the light-harvesting complexes and very noisy environments surrounding them, the energy absorbed by these complexes is efficiently transmitted to the reaction centre. In this talk, we investigate the role of rotational symmetry within the light-harvesting complexes of purple bacteria on the efficiency of energy transfer. Our results demonstrate that breaking the symmetry of these complexes will attenuate the performance ... 15:00 - 16:00 Weekly Seminar Design and Measurement of Solenoid Magnets for IPM Electron Linac School PARTICLES AND ACCELERATORS IPM Linac is an 8 MeV electron linear accelerator. This machine consists of an electron gun, a buncher and two accelerating structures. Beam focusing in the buncher and accelerating tubes provides by solenoid magnets. In my presentation I will overview solenoid design to provide beam dynamic requirements. Then I will talk about magnetic measurement system and the main challenges for testing these solenoids. ... |
