Pb/InAs nanowire josephson junction with high critical current and magnetic flux focusing.

Nano letters

Paajaste J, Amado M, Roddaro S, Bergeret FS, Ercolani D, Sorba L, Giazotto F.
PMID: 25671540
Nano Lett. 2015 Mar 11;15(3):1803-8. doi: 10.1021/nl504544s. Epub 2015 Feb 16.

We have studied mesoscopic Josephson junctions formed by highly n-doped InAs nanowires and superconducting Ti/Pb source and drain leads. The current-voltage properties of the system are investigated by varying temperature and external out-of-plane magnetic field. Superconductivity in the Pb...

Magnetically-driven colossal supercurrent enhancement in InAs nanowire Josephson junctions.

Nature communications

Tiira J, Strambini E, Amado M, Roddaro S, San-Jose P, Aguado R, Bergeret FS, Ercolani D, Sorba L, Giazotto F.
PMID: 28401951
Nat Commun. 2017 Apr 12;8:14984. doi: 10.1038/ncomms14984.

The Josephson effect is a fundamental quantum phenomenon where a dissipationless supercurrent is introduced in a weak link between two superconducting electrodes by Andreev reflections. The physical details and topology of the junction drastically modify the properties of the...

Crystal Phases in Hybrid Metal-Semiconductor Nanowire Devices.

Nano letters

David J, Rossella F, Rocci M, Ercolani D, Sorba L, Beltram F, Gemmi M, Roddaro S.
PMID: 28231001
Nano Lett. 2017 Apr 12;17(4):2336-2341. doi: 10.1021/acs.nanolett.6b05223. Epub 2017 Feb 28.

We investigate the metallic phases observed in hybrid metal-GaAs nanowire devices obtained by controlled thermal annealing of Ni/Au electrodes. Devices are fabricated onto a SiN membrane compatible with transmission electron microscopy studies. Energy dispersive X-ray spectroscopy allows us to...

Nonthermal production of gravitinos and inflatinos.

Physical review letters

Nilles HP, Peloso M, Sorbo L.
PMID: 11497758
Phys Rev Lett. 2001 Jul 30;87(5):051302. doi: 10.1103/PhysRevLett.87.051302. Epub 2001 Jul 11.

We explicitly calculate nonthermal gravitino production during the preheating period in the inflationary Universe. Contrary to earlier investigations, we consider a two-field model to separate the mechanisms of supersymmetry breaking and inflation. We show that the superpartner of the...

Identification of four families of yCCR4- and Mg2+-dependent endonuclease-related proteins in higher eukaryotes, and characterization of orthologs of yCCR4 with a conserved leucine-rich repeat essential for hCAF1/hPOP2 binding.

BMC genomics

Dupressoir A, Morel AP, Barbot W, Loireau MP, Corbo L, Heidmann T.
PMID: 11747467
BMC Genomics. 2001;2:9. doi: 10.1186/1471-2164-2-9. Epub 2001 Nov 22.

BACKGROUND: The yeast yCCR4 factor belongs to the CCR4-NOT transcriptional regulatory complex, in which it interacts, through its leucine-rich repeat (LRR) motif with yPOP2. Recently, yCCR4 was shown to be a component of the major cytoplasmic mRNA deadenylase complex,...

Nonlinear quasiparticle tunneling between fractional quantum hall edges.

Physical review letters

Roddaro S, Pellegrini V, Beltram F, Biasiol G, Sorba L, Raimondi R, Vignale G.
PMID: 12570444
Phys Rev Lett. 2003 Jan 31;90(4):046805. doi: 10.1103/PhysRevLett.90.046805. Epub 2003 Jan 29.

Remarkable nonlinearities in the differential tunneling conductance between fractional quantum Hall edge states at a constriction are observed in the weak-backscattering regime. In the nu=1/3 state a peak develops as temperature is increased and its width is determined by...

Photobehavior of the geometrical isomers of two 1,4-distyrylbenzene analogues with side groups of different electron donor/acceptor character.

The journal of physical chemistry. A

Ciorba S, Galiazzo G, Mazzucato U, Spalletti A.
PMID: 20857985
J Phys Chem A. 2010 Oct 14;114(40):10761-8. doi: 10.1021/jp105383e.

The photobehavior of two 1,4-distyrylbenzene analogues where the central benzene ring is asymmetrically substituted with a pyrid-4-ylethenyl group at one side and thien-2-ylethenyl or a p-nitrostyryl group at the other side, has been studied in two solvents at room...

A minimum principle in mRNA editing?.

Journal of biological physics

Frappat L, Sciarrino A, Sorba P.
PMID: 23345755
J Biol Phys. 2002 Mar;28(1):27-38. doi: 10.1023/A:1016291500859.

mRNA editing of sequences of many species is analyzed. The nature of the inserted nucleotides and the position of the insertion sites, once fixed the edited peptide chain, are explained by introducing a minimum principle in the framework of...

According to the guidelines of the European Stroke Organization (ESO) and the American Stroke Association (ASA), acute stroke patients should be managed at stroke units that include well organized pre- and in-hospital care. In ischemic stroke the restoration of...
