Nonreciprocal transmission of microwaves through a long Josephson junction
A. L. Pankratov, K. G. Fedorov, M. Salerno +2
Nonreciprocal microwave transmission through a long Josephson junction in the flux-flow regime is studied analytically and numerically within the framework of the perturbed sine-Go…
Localization-delocalization transition of dipolar bosons in a four-well potential
Giovanni Mazzarella, Vittorio Penna
We study interacting dipolar atomic bosons in a four-well potential within a ring geometry and outline how a four-site Bose-Hubbard (BH) model including next-nearest-neighbor inter…
Realization of a diamond based high density multi electrode array by means of deep ion beam lithography
Federico Picollo, Alfio Battiato, Ettore Bernardi +5
In the present work we report about a parallel-processing ion beam fabrication technique whereby high-density sub-superficial graphitic microstructures can be created in diamond. I…
Universal Quasi-Static Limit for Plasmon-Enhanced Optical Chirality
Marco Finazzi, Paolo Biagioni, Michele Celebrano +1
We discuss the possibility of enhancing the chiroptical response from molecules uniformly distributed around nanostructures that sustain localized plasmon resonances. We demonstrat…
Phase dynamics in graphene-based Josephson junctions in the presence of thermal and correlated fluctuations
Claudio Guarcello, Davide Valenti, Bernardo Spagnolo
In this work we study by numerical methods the phase dynamics in ballistic graphene-based short Josephson junctions. The supercurrent through a graphene junction shows a non-sinuso…
Discrete bright solitons in Bose-Einstein condensates and dimensional reduction in quantum field theory
Luca Salasnich
We first review the derivation of an effective one-dimensional (1D) discrete nonpolynomial Schrödinger equation from the continuous 3D Gross-Pitaevskii equation with transverse har…
