Thursday 7th February: STP Seminar – “Localization Counteracts Decoherence in Noisy Floquet Topological Chains”

Title: “Localization Counteracts Decoherence in Noisy Floquet Topological Chains” Speaker: Maresa Rieder (formerly Weizmann Institute) Abstract: The topological phases of periodically driven, or Floquet systems, rely on a perfectly periodic modulation of system parameters in time. Even the… Read More
