The range of geometrical frustration in lattice spin models
Pierre Ronceray, Bruno Le Floch
The concept of geometrical frustration in condensed matter physics refers to the fact that a system has a locally preferred structure with an energy density lower than the infinite…
KdV charges in theories and new models with super-Hagedorn behavior
Bruno Le Floch, Márk Mezei
Two-dimensional CFTs and integrable models have an infinite set of conserved KdV higher spin currents. These currents can be argued to remain conserved under the deforma…
Marginal Deformations of 3d N=4 Linear Quiver Theories
Constantin Bachas, Ioannis Lavdas, Bruno Le Floch
We study superconformal deformations of the theories of Gaiotto-Hanany-Witten, paying special attention to mixed-branch operators with both electrically- and m…
Action of Weyl group on zero weight space
Bruno Le Floch, Ilia Smilga
For any simple complex Lie group we classify irreducible finite-dimensional representations for which the longest element of the Weyl group acts nontrivially on the zero…
On the global evolution of self-gravitating matter. Nonlinear interactions in Gowdy symmetry
Bruno Le Floch, Philippe G. LeFloch
We are interested in the evolution of a compressible fluid under its self-generated gravitational field. Assuming here Gowdy symmetry, we investigate the algebraic structure of the…
