Riemann meets Goldstone: magnon scattering off quantum Hall skyrmion crystals probes interplay of symmetry breaking and topology
Nilotpal Chakraborty, Roderich Moessner, Benoit Doucot
We introduce a model to study magnon scattering in skyrmion crystals, sandwiched between ferromagnets which act as the source of magnons. Skyrmions are topological objects while sk…
Topological power pumping in quantum circuits
Jacquelin Luneau, Clément Dutreix, Quentin Ficheux +4
In this article, we develop a description of topological pumps as slow classical dynamical variables coupled by a quantum system. We discuss the cases of quantum Hall pumps, Thoule…
Topological Electrostatics
B. Douçot, R. Moessner, D. L. Kovrizhin
We present a theory of optimal topological textures in nonlinear sigma-models with degrees of freedom living in the Grassmannian manifold. These textures describ…
Hybrid light-matter networks of Majorana zero modes
L. C. Contamin, M. R. Delbecq, B. Dou çot +2
Topological excitations, such as Majorana zero modes, are a promising route for encoding quantum information. Topologically protected gates of Majorana qubits, based on their braid…
Berry phase in superconducting multiterminal quantum dots
Benoit Doucot, Romain Danneau, Kang Yang +2
We report on the study of the non-trivial Berry phase in superconducting multiterminal quantum dots biased at commensurate voltages. Starting with the time-periodic Bogoliubov-de G…
Engineering the Floquet spectrum of superconducting multiterminal quantum dots
Régis Mélin, Romain Danneau, Kang Yang +2
Here we present a theoretical investigation of the Floquet spectrum in multiterminal quantum dot Josephson junctions biased with commensurate voltages. We first draw an analogy bet…
