Partition function of the Kitaev quantum double model
Anna Ritz-Zwilling, Benoît Douçot, Steven H. Simon +2
We compute the degeneracy of energy levels in the Kitaev quantum double model for any discrete group on any planar graph forming the skeleton of a closed orientable surface of…
Experimental realization of a transmon qubit
Erwan Roverc'h, Alvise Borgognoni, Marius Villiers +7
Superconducting circuits with embedded symmetries are good candidates to robustly protect quantum information from dominant error channels. The qubit, consisting of an…
Robust flat bands of the honeycomb wire network
Chunxiao Liu, Benoît Douçot, Jérôme Cayssol
We show that periodic honeycomb networks of ballistic conducting channels generically host exact flat bands spanning the entire Brillouin zone. These flat bands are independent of…
Dynamical correlations and domain wall relocalization in transverse field Ising chains
Philippe Suchsland, Benoît Douçot, Vedika Khemani +1
We study conventional and out-of-time-ordered correlators (OTOCs) for a wide variety of transverse field Ising chains: classical and quantum, clean and disordered, and integrable a…
Orbital Hall Effect and Angular Momentum Dynamics in Confined Geometries
Egor I. Kiselev, Benoît Douçot, Roderich Moessner
We present an analysis of the orbital Hall effect (OHE) in a strip geometry and derive a formula for the orbital angular momentum (OAM) accumulation at the edges. The result is exp…
