Abstract:
We will present the geometrical and algebraic structure of Kitaev models with both abelian and non-abelian discrete gauge group.

10. Quantum Measure in Regge Calculus

Talk

Abstract:
In a recent paper, A. D’Adda has shown that assigning a length to each link and coordinates to each labelled vertex it is possible to fix a non-Euclidean flat metric and a reference frame in each simplex invariant under GL(n,R). The metric tensor is function of the link lengths and of the coordinates of the vertices. We will show that by performing a gauge-fixing on the metric...

12. Dynamics from Geometry in Stokes Flow

Marco Laudato

Talk

Abstract:
Particle-laden flows are everywhere: a fluid carries a dispersed population of small rigid bodies whose shapes can be as simple as spheres or as intricate as helices. This talk asks a basic question at the interface of geometry and dynamics. In the limit where inertia is negligible (Re → 0), can the shape of a particle, together with a time-dependent forcing that averages to zero,...

5. Defining hybrid quantum-classical ensembles

Talk

Abstract:
We present a brief summary of the different geometric tools that we developed over the last 15 years to model hybrid quantum-classical systems. Usually obtained as an approximation of an initially full quantum model where two different mass or time scales exist, these models offer a very useful framework for numerical simulations of molecular systems. We will review the geometrical...
