Cours du Professeur Philip Stamp au Collège de France

Philip STAMP donnera quatre cours au Collège de France sur les sujets suivants :

  • 1) Decoherence 1 : Oscillator and Spin Baths
    Explanation of the oscillator bath model (Feynman-Vernon/Caldeira-Leggett) and the spin bath model (Prokof’ev-Stamp) of quantum environments. Their essential differences – describing delocalized and localized modes in the environment, respectively. Decoherence and dissipative phenomena discussed using these 2 models.
  • 2) Decoherence 2 : Theory vs Experiment
    Experiments on decoherence in condensed matter systems (magnetic systems, superconductors, biological systems), and in optomechanical systems. Why theory so often disagrees with experiment, and what is lacking in the theory. Three kinds of decoherence (environmental, 3rd party, and intrinsic).
  • 3) Gravity 1 : Gravity vs Quantum Mechanisms
    Decoherence and quantum computation – the role of spin and oscillator baths, and of long-range interactions and correlated errors. Concrete examples : solid state physics and quantum optical qubit designs. Remarks on quantum measurements, and on decoherence for large-scale superpositions.
  • 4) Gravity 2 : Correlated Worldline Theory
    Why Quantum Mechanics conflicts with General Relativity, and possible solutions. A new theory of quantum gravity, in which gravity correlates the different paths in the path integral for any quantum system. Implications for optomechanical table-top experiments, for quantum measurements, and for ideas about “gravitational decoherence”.

Ces cours auront lieu le lundi 9 mai, le jeudi 19 mai et les lundis 23 et 30 mai 2016 à 11 heures, salle 5 (11 place Marcelin-Berthelot, Paris 5e).
