Extended Bose Hubbard model of interacting bosonic atoms in optical lattices: from superfluidity to density waves
G. Mazzarella, S. M. Giampaolo, F. Illuminati
For systems of interacting, ultracold spin-zero neutral bosonic atoms, harmonically trapped and subject to an optical lattice potential, we derive an Extended Bose Hubbard (EBH) mo…
A note on Tachyon dynamics
F. Canfora
A suitable splitting of tachyon field equation is able to disclose non trivial properties of Born-Infeld (some known, some unexpected) and Polyakov actions; the tachyon equation al…
Subharmonic gap structures and Josephson effect in MgB2/Nb micro-constrictions
Filippo Giubileo, Marco Aprili, Fabrizio Bobba +3
Superconducting micro-constrictions between Nb tips and high quality MgB pellets have been realized by means of a point-contact inset, driven by a micrometric screw. Measurem…
Point-Contact Spectroscopy on RuSr2GdCu2O8
Samanta Piano, Fabrizio Bobba, Filippo Giubileo +2
We present Point-Contact experiments on polycrystalline RuSrGdCuO samples. The majority of tunneling curves shows a zero-bias conductance peak, which is modeled by assu…
Point Contact Study of the Superconducting Order Parameter in RuSr2GdCu2O8
Samanta Piano, Fabrizio Bobba, Filippo Giubileo +2
We have performed a detailed study of the conductance characteristics obtained by point contact junctions realized between a normal Pt/Ir tip and syntered RuSr2GdCu2O8 (Ru-1212) sa…
Nonlinear brain dynamics and many-body field dynamics
Walter J. Freeman, Giuseppe Vitiello
We report measurements of the brain activity of subjects engaged in behavioral exchanges with their environments. We observe brain states which are characterized by coordinated osc…
