Title: Cold-atom interacting topological insulators and their connection to high-energy physics
Abstract: Understanding the robustness of topological phases of matter in the presence of strong interacions is a difficult challenge of modern theoretical physics.The indentification of simplified toy models yields a testing ground to develop and nechmark new theoretical tools to understand the interplay between topological features and stong-correlation effects. In this talk, I will describe the imbalanced Creutz-Hubbard ladder, a paradigmatic topological-insulator model that can be realized in a synthetic periodically-modulated ladder made of two intenal states of ultracold fermionic atoms in a one-dimensional optical lattice. I will discuss the different tools we have developed to understand its phase diagram, and their numerical benchmark via Matrix Product State methods. Moreover, I will discuss interesting connections to high-energy physics models, which were put forth in the context of quantum chromidynamics, and open an interesting dialogue between both disciplines.
