Universality of Boundary Charge Fluctuations
Clara S. Weber, Kiryl Piasotski, Mikhail Pletyukhov +4
We establish the quantum fluctuations of the charge accumulated at the boundary of an insulator as an integral tool to characterize phase transitions where a direct…

The interacting Rice-Mele model: bulk and boundaries
Y. -T. Lin, D. M. Kennes, M. Pletyukhov +3
We investigate the interacting, one-dimensional Rice-Mele model, a prototypical fermionic model of topological properties. To set the stage, we firstly compute the single-particle…

Chiral 1D Floquet topological insulators beyond rotating wave approximation
Dante M. Kennes, Niclas Müller, Mikhail Pletyukhov +6
We study one-dimensional (1D) Floquet topological insulators with chiral symmetry going beyond the standard rotating wave approximation. The occurrence of many anticrossings betwee…
