Aggregation-engineered loss-tolerant strong coupling in metallic microcavities

Andrea Betti, Eleonora Cara, Giulia Serrano +7

Room-temperature strong coupling in organic microcavities is usually achieved by combining high-quality optical resonators with highly ordered excitonic media, a requirement that l…

Berezinskii-Kosterlitz-Thouless to BCS-like superconducting transition crossover driven by weak magnetic fields in ultra-thin NbN films

Meenakshi Sharma, Sergio Caprara, Andrea Perali +5

The Berezinskii-Kosterlitz-Thouless (BKT) transition in ultra-thin NbN films is investigated in the presence of weak perpendicular magnetic fields. A jump in the phase stiffness at…

Complex phase-fluctuation effects correlated with granularity in superconducting NbN nanofilms

Meenakshi Sharma, Manju Singh, Rajib K. Rakshit +5

Superconducting nanofilms are tunable systems that can host a 3D-2D dimensional crossover, leading to the Berezinskii-Kosterlitz-Thouless (BKT) superconducting transition approachi…

Dimensional crossover and incipient quantum size effects in superconducting niobium nanofilms

N. Pinto, S. J. Rezvani, Andrea Perali +5

Superconducting and normal state properties of sputtered Niobium nanofilms have been systematically investigated, as a function of film thickness in a d=9-90 nm range, on different…

Universality of transport properties of ultra-thin oxide films

V. Lacquaniti, M. Belogolovskii, C. Cassiago +3

We report low-temperature measurements of current-voltage characteristics for highly conductive Nb/Al-AlOx-Nb junctions with thicknesses of the Al interlayer ranging from 40 to 150…

Realization and preliminary measurements on a 94 GHz SIS mixer

L. Oberto, N. De Leo, M. Fretto +3

In this paper we present the realization and a preliminary characterization of a SIS based receiver. It has been developed for the MASTER experiment that consists in a three-band S…
