I am currently an Assistant Professor (i.e., an RTD-B in the Italian jargon) at the Department of Physics “E. R. Caianiello”, University of Salerno (Italy), and an associate member of INFN (Napoli Section, Group V). My research sits at the interface of condensed-matter theory and superconducting electronics, with a strong focus on Josephson-based devices for quantum technologies, spanning from mesoscopic transport to circuit-level modeling and noise-driven dynamics.
Current research directions
My activity is organized around a few tightly connected themes:
Noise-induced phenomena in nonlinear superconducting systems (including non-Gaussian/Lévy fluctuations), with applications ranging from device stability and switching statistics to detection strategies in low-temperature platforms.
Magneto-electric and anomalous Josephson effects in hybrid systems with spin–orbit coupling and/or magnetic textures, including φ0-junction physics, Josephson diode phenomenology, and signatures of non-trivial topology in nanostructured junctions.
Mesoscopic heat and charge transport in superconducting tunnel junctions and interferometers, including thermoelectric signatures linked to order-parameter properties and device concepts for coherent control of heat currents.
Modeling and nonlinear dynamics of Josephson Traveling-Wave Parametric Amplifiers (JTWPA) and related architectures, including the impact of non-sinusoidal current–phase relations, resonant phase-matching strategies, and the onset of nonlinear/chaotic regimes relevant to quantum-limited detection and large-scale readout.
Theoretical work supporting quantum sensing with superconducting qubits and the development of itinerant single-photon counters with high efficiency and reduced dark counts, targeting fundamental-physics experiments.
Previous Positions
Before joining the University of Salerno, I was a postdoctoral researcher at the Materials Physics Center in San Sebastián (Spain), where I worked on magneto-electric effects at superconducting interfaces and developed concepts for non-volatile superconducting memory based on the bistability of current-biased anomalous junctions.
Earlier, at CNR-NANO (NEST, Pisa), I carried out theoretical research on coherent caloritronics and mesoscopic transport in Josephson nanostructures, proposing device concepts that exploit controlled temperature gradients and phase-coherent heat currents.
My PhD (University of Palermo) focused on the theory of noise-induced effects in long and short Josephson junctions, including solitonic excitations and anomalous diffusion in strongly nonlinear superconducting systems.
Projects and collaborations
A significant part of my current activity is carried out within collaborative research programs, including INFN initiatives on developments on demonstrative quantum architectures (QUART&T), or quantum-limited readout and parametric amplification (DARTWARS) and quantum sensing with superconducting qubits (Qub-IT), as well as earlier work on single microwave-photon detection (SIMP).
More recently, I have contributed to PNRR/NQSTI projects focused on topological and driven superconducting heterostructures (e.g., SPUNTO, TOPQIN) and on enabling technologies for quantum sensing and amplification (e.g., Nb-based Josephson arrays for parametric amplification, X-band superconducting amplifiers).
