Mean-field dynamics of an infinite-range interacting quantum system: chaos, dynamical phase transition, and localisation
Bojan Žunkovič, Antonio Zegarra
We investigate the dynamical properties of the XY spin 1/2 chain with infinite-range transverse interactions and find a dynamical phase transition with a chaotic dynamical phase. I…
A supervised learning algorithm for interacting topological insulators based on local curvature
Paolo Molignini, Antonio Zegarra, Evert van Nieuwenburg +2
Topological order in solid state systems is often calculated from the integration of an appropriate curvature function over the entire Brillouin zone. At topological phase transiti…
Persistent currents and spin torque caused by percolated quantum spin Hall state
Antonio Zegarra, J. Carlos Egues, Wei Chen
Motivated by recent experiments, we investigate the quantum spin Hall state in 2D topological insulator/ferromagnetic metal planar junctions by means of a tight-binding model and l…
Corroborating the bulk-edge correspondence in weakly interacting 1D topological insulators
Antonio Zegarra, Denis R. Candido, J. Carlos Egues +1
We present a Green's function formalism to investigate the topological properties of weakly interacting one-dimensional topological insulators, including the bulk-edge corresponden…
