Séminaire du LPTMS: Michele Filippone *** séminaire exceptionnel ***

Controlled Parity Switch of Persistent Currents and Topological charge-pumping effects induced by bulk magnetic fluxes Michele Filippone (Université de Genève, Suisse) We investigate persistent currents for a fixed number of fermions in periodic quantum ladders threaded by Aharonov-Bohm and transverse magnetic fluxes Φ and χ. We show that the coupling between ladder legs provides a …

Séminaire du LPTMS: Alexandru Petrescu *** séminaire exceptionnel ***

Fluxon-based quantum simulation in circuit QED Alexandru Petrescu (Department of electrical engineering, Princeton University, USA) Long-lived fluxon excitations can be trapped inside a superinductor ring, which can be realized with a long array of Josephson junctions, one of which offers the input/output path for the magnetic flux [1]. The superinductor ring can be separated into …
