Geometrical approach and topological electron density in the superconductor
Karyn Le Hur, Kabir Narayanan, Óscar Mañas Chambert
We present an analysis on the geometrical and physical nature of the superconductor on the square lattice, with an emphasis on the topological phase transition at half…
Free Majorana Fermions with Superconducting Quantum Wires and a Magnetic Impurity
Karyn Le Hur
Through the two-channel Kondo model, I address a magnetic spin-1/2 impurity interacting with a bound state of spin origin at the edge in a Luther-Emery liquid showing a spin gap in…
Interacting Stochastic Topology and Mott Transition from Light Response
Philipp W. Klein, Adolfo G. Grushin, Karyn Le Hur
We develop a stochastic description of the topological properties in an interacting Chern insulator. We confirm the Mott transition's first-order nature in the interacting Haldane…
Real-Time Ramsey Interferometry in Fractional Quantum Hall States
Tal Goren, Karyn Le Hur
We study the time-dependent dynamical phase of fractional quasiparticles in quantum Hall states using Ramsey interferometry. A Ramsey two-pulse voltage modulation generates an inte…
Valence bond fluctuations in the Kitaev spin model
Fan Yang, Kirill Plekhanov, Karyn Le Hur
We introduce valence bond fluctuations, or bipartite fluctuations associated to bond-bond correlation functions, to characterize quantum spin liquids and their entanglement propert…
Bipartite Fluctuations and Topology of Dirac and Weyl Systems
Loïc Herviou, Karyn Le Hur, Christophe Mora
Bipartite fluctuations can provide interesting information about entanglement properties and correlations in many-body quantum systems. We address such fluctuations in relation wit…
