  1. 17. Upper bounds on gyrokinetic instabilities

    Main track
    Oral presentation

    For several decades, an enormous effort has been devoted to the gyrokinetic theory of instabilities and turbulence in stellarators and tokamaks. Thousands of papers have been published on this subject, and millions of lines of code have been written for the purpose of numerically solving gyrokinetic equations.

    As a result of this effort, a great deal of knowledge about various...

  2. 7. Unified theory of classical and quantum ergotropy

    Main track
    Oral presentation

    Quantifying the ergotropy (also known as available energy), namely the maximal amount of energy that can be extracted from a thermally isolated system, is a central problem in quantum thermodynamics. Notably, the same problem has been long studied for classical systems as well, e.g., in plasma physics and astrophysics, where the basic principles for its solution are known for the case of...

  3. 37. Ground states: constraints from the field equations and unresolved issues
    Ralf Johannes Josephus Mackenbach (EPFL-SPC)

    Main track
    Oral presentation

    Given a collisionless plasma, how much of its energy can turbulence actually extract? A natural answer is to rearrange the distribution function into its lowest-energy configuration, subject to the constraints of the underlying dynamics; an idea that has been used across time and disciplines, from Lorenz's available potential energy in meteorology to Gardner's restacking argument [1] and the...
