A ballistic quantum ring Josephson interferometer
A. Fornieri, M. Amado, F. Carillo +5
We report the realization of a ballistic Josephson interferometer. The interferometer is made by a quantum ring etched in a nanofabricated two-dimensional electron gas confined in…
Projected sensitivity to light WIMP-like particles of the BULLKID-DM experiment
Matteo Folcarelli, A. Acevedo-RenterÃa, L. E. Ardila-Perez +39
BULLKID-DM is an experiment designed for the direct searches of particle dark matter candidates with mass around 1 GeV, or below, and cross-section with nucleons smaller than $10^{…
Energy calibration of bulk events in the BULLKID detector
M. Folcarelli, D. Delicato, A. Acevedo-RenterÃa +39
BULLKID is a cryogenic, solid-state detector designed for direct searches of particle Dark Matter candidates, with mass GeV/c, and coherent neutrino-nucleus scatte…
Background of the BULLKID detector array operated with moderate shield on surface
D. Delicato, A. Acevedo-RenterÃa, M. Folcarelli +42
We present the operation with moderate radiation shield in a surface laboratory of BULLKID (BULky and Low-threshold Kinetic Inductance Detector), a cryogenic detector for searches…
Feasibility of biepitaxial YBaCuO Josephson junctions for fundamental studies and potential circuit implementation
F. Tafuri, F. Carillo, F. Lombardi +7
We present various concepts and experimental procedures to produce biepitaxial YBaCuO grain boundary Josephson junctions. The device properties have an interesting phenomenology re…
Electrostatic tailoring of magnetic interference in quantum point contact ballistic Josephson junctions
M. Amado, A. Fornieri, F. Carillo +4
The magneto-electrostatic tailoring of the supercurrent in quantum point contact ballistic Josephson junctions is demonstrated. An etched InAs-based heterostructure is laterally co…
Real-Time Readout System Design for the BULLKID-DM Experiment: Enhancing Dark Matter Search Capabilities
T. Muscheid, R. Gartmann, L. E. Ardila-Perez +41
The BULLKID-DM experiment aims to detect WIMP-like potential Dark Matter particles with masses below 1 GeV/c^2. Sensing these particles is challenging, as it requires nuclear recoi…
Resolving the effects of frequency dependent damping and quantum phase diffusion in YBaCuO Josephson junctions
D. Stornaiuolo, G. Rotoli, D. Massarotti +4
We report on the study of the phase dynamics of high critical temperature superconductor Josephson junctions. We realized YBaCuO (YBCO) grain boundary (GB) biepitax…
Flux flow of Abrikosov-Josephson vortices along grain boundaries in high-temperature superconductors
A. Gurevich, M. S. Rzchowski, G. Daniels +5
We show that low-angle grain boundaries (GB) in high-temperature superconductors exhibit intermediate Abrikosov vortices with Josephson cores, whose length along GB is smaller…
Singlet-triplet transition in a few-electron lateral InGaAs-InAlAs quantum dot
F. Deon, V. Pellegrini, F. Carillo +4
The magnetic-field evolution of Coulomb blockade peaks in lateral InGaAs/InAlAs quantum dots in the few-electron regime is reported. Quantum dots are defined by gates evaporated on…
Spin separation in a T ballistic nanojunction due to lateral-confinement-induced spin-orbit-coupling

We propose a new scheme of spin filtering employing ballistic nanostructures in two dimensional electron gases (2DEGs). The proposal is essentially based on the spin-orbit (SO) int…
Superconducting properties of lifted-off Niobium nanowires

Hybrid superconductor/semiconductor devices play a crucial role in advancing quantum science and technology by merging the properties of superconductors and semiconductors. To oper…
High critical-current density and scaling of phase-slip processes in YBaCuO nanowires
G. Papari, F. Carillo, D. Stornaiuolo +3
YBaCuO nanowires were reproducibly fabricated down to widths of 50 nm. A Au/Ti cap layer on YBCO yielded high electrical performance up to temperatures above 80 K in single nanowir…
