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…
Frustrated extended Bose-Hubbard model and deconfined quantum critical points with optical lattices at the anti-magic wavelength
Niccolò Baldelli, Cesar R. Cabrera, Sergi Julià-Farré +2
The study of geometrically frustrated many-body quantum systems is of central importance to uncover novel quantum mechanical effects. We design a scheme where ultracold bosons trap…
Fragmented superconductivity in the Hubbard model as solitons in Ginzburg-Landau theory
Niccolò Baldelli, Hannes Karlsson, Benedikt Kloss +2
The phenomena of superconductivity and charge density waves are observed in close vicinity in many strongly correlated materials. Increasing evidence from experiments and numerical…
Detecting Majorana Zero Modes via Strong Field Dynamics
Niccolò Baldelli, Utso Bhattacharya, Daniel González-Cuadra +2
We propose a protocol to detect topological phase transitions of one-dimensional -wave superconductors from their harmonic emission spectrum in strong fields. Specifically, we i…
Variational Quantum Anomaly Detection: Unsupervised mapping of phase diagrams on a physical quantum computer
Korbinian Kottmann, Friederike Metz, Joana Fraxanet +1
One of the most promising applications of quantum computing is simulating quantum many-body systems. However, there is still a need for methods to efficiently investigate these sys…
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…
