Unlikely intersections on the p-adic formal ball

We investigate generalizations along the lines of the Mordell-Lang conjecture of the author's p-adic formal Manin-Mumford results for n-dimensional p-divisible formal groups F. In particular, given a finitely generated subgroup (sic) of F(Q(p)) and a close ...

On p-adic Versions of the Manin-Mumford Conjecture

Vlad Serban

We establish p-adic versions of the Manin-Mumford conjecture, which states that an irreducible subvariety of an abelian variety with dense torsion has to be the translate of a subgroup by a torsion point. We do so in the context of certain rigid analytic s ...

Real time magnetic control of the snowflake plasma configuration in the TCV tokamak

Stefano Coda, Jean-Marc Moret, Holger Reimerdes, Benoît Labit, Federico Alberto Alfredo Felici, Cristian Galperti, Roberto Maurizio, Himank Anand

The novel plasma position and shape controller of the TCV tokamak aids in the precise control of complex configurations such as snowflake (SF) divertors. The ability of the controller design to simultaneously control the position, shape, divertor leg and X ...

Distributed digital real-time control system for the TCV tokamak and its applications

Olivier Sauter, Basil Duval, Stefano Coda, Timothy Goodman, Jean-Marc Moret, Federico Alberto Alfredo Felici, Cristian Galperti, Doohyun Kim, Himank Anand

A key feature of the new digital plasma control system installed on the TCV (Tokamak à Configuration Variable) tokamak is its possibility to rapidly design, test and deploy real-time algorithms. It accommodates hundreds of diagnostic inputs and actuator ou ...

Weak Finsler structures and the Funk weak metric

Marc Troyanov

We discuss general notions of metrics and of Finsler structures which we call weak metrics and weak Finsler structures. Any convex domain carries a canonical weak Finsler structure, which we call its tautological weak Finsler structure. We compute distance ...

GaN light-emitting diodes with Archimedean lattice photonic crystals

Elison de Nazareth Matioli, Henri Benisty

We study GaN-based light emitting diodes incorporating an omnidirectional photonic crystal with Archimedean lattice. Photonic bands are observed over several Brillouin zones, revealing reciprocal space symmetries and evidencing the omnidirectionality of th ...
