Deconfined quantum critical points in fermionic systems with spin-charge separation
Niccolò Baldelli, Arianna Montorsi, Sergi Julià-Farré +3
Deconfined quantum critical points are intriguing transition points not predicted by the Landau-Ginzburg-Wilson symmetry-breaking paradigm which are usually identified by the appea…

Tracing non-Abelian anyons via impurity particles
Niccolò Baldelli, Bruno Juliá-Díaz, Utso Bhattacharya +2
Non-Abelian excitations are an interesting feature of many fractional quantum Hall phases, including those phases described by the Moore-Read (or Pfaffian) wave function. However,…

Fractional angular momentum and anyon statistics of impurities in Laughlin liquids
Tobias Graß, Bruno Juliá-Díaz, Niccolò Baldelli +2
The elementary excitations of a fractional quantum Hall liquid are quasiparticles or quasiholes which are neither bosons nor fermions, but so-called anyons. Here we study impurity…
