| 11:00 - 12:00 Quantum information biweekly journal club Fundamental limitations for quantum and nanoscale thermodynamics School NANO SCIENCES Fundamental limitations for quantum and nanoscale thermodynamics The relationship between thermodynamics and statistical physics is valid in the thermodynamic limit-when the number of particles becomes very large. Here we study thermodynamics in the opposite regime-at both the nanoscale and when quantum effects become important. Applying results from quantum information theory, we construct a theory of thermodynamics in these limits. We derive general criteria for thermodynamical state transitions, and, as special cases, find two free energies: one that quantifies the deterministically extractable work from a small system in ... 14:00 - 15:30 Weekly Seminar Gaia - one billion objects in 3+ dimensions School ASTRONOMY Gaia is the European Space Agency mission which is revolutionizing our knowledge of our Milky Way Galaxy, providing a census of positions, motions, colors, and properties of 2.5 billion stars. Gaia's data will revolutionist much of astronomy, from near-Earth asteroids, through stellar evolution, the structure, formation, and evolution of our Milky Way Galaxy, the distribution of Dark Matter in the Milky Way, the number of planetary systems around other stars, the cosmological distance scale, and fundamental tests of General Relativity. In addition to the wealth of position data, Gaia's camera repeatedly scanning the sky discovers variable and ... 14:00 - 15:00 Weekly Seminar The Concepts and Applications of Fractional Order Differential Calculus in Modelling of Viscoelastic Systems School NANO SCIENCES The Concepts and Applications of Fractional Order Differential Calculus in Modelling of Viscoelastic Systems Viscoelasticity and related phenomena are of great importance in the study of mechanical properties of material especially, biological materials. Certain materials show some complex effects in mechanical tests, which cannot be described by standard linear equation (SLE) mostly owing to shape memory effect during deformation. Recently, researchers have been applying fractional calculus in order for probing viscoelasticity of such materials with a high precision. Fractional calculus is a powerful tool for modelling comp ... 15:30 - 16:30 Weekly Seminar Isolated Prompt Photon Production in p-Pb Collisions and Nuclear Modifications of Parton Densities School PARTICLES AND ACCELERATORS Prompt photon production is known as a powerful tool for testing perturbative QCD predictions and also the validity of parton densities in the nucleon and nuclei especially of the gluon. In this talk, we are going to discuss the impact of input nuclear modifications obtained from different global analyses by various groups on the isolated prompt photon production in p-Pb collisions at forward rapidity at the LHC. We show that future measurements with ALICE will be very useful not only for decreasing the uncertainty of the gluon nuclear modification, but also to accurately determine its central values, especially in the shadowing region. ... |
