This note is an expanded version of the author's contribution to the Proceedings of the ICMP Santiago, 2015, and is based on a talk given by the second author at the same Congress. It concerns aExpand
Mean--field stability for the junction of quasi 1D systems with Coulomb interactions
Junctions appear naturally when one studies surface states or transport properties of quasi one dimensional materials such as carbon nanotubes, polymers and quantum wires. These materials can be seenExpand

Ballistic Transport for Limit-Periodic Jacobi Matrices with Applications to Quantum Many-Body Problems
We study Jacobi matrices that are uniformly approximated by periodic operators. We show that if the rate of approximation is sufficiently rapid, then the associated quantum dynamics are ballistic inExpand
