ABSTRACT
Superconducting quantum interference devices (SQUIDs) have been realized with a built-in π/2 phase shift of the superconducting wave function. Its design is inspired by the phase-shifter concept, first proposed by Ioffe et al. [Nature 398, 679 (1999)] as the key element in a solid-state qubit configuration. It exploits the dx2-y2 order parameter symmetry in the high-Tc cuprates in multilayer structures based on YBa2Cu3O7-Nb ramp-type Josephson contacts. By reversing the sign of the persistent circulating current in the phase-shifting element, the π/2 SQUID can be controllably switched between two energetically degenerate ground states, with complementary magnetic flux dependencies.

    We have found that small long-type magnetoelectric (ME) laminate composites of magnetostrictive Tb1-xDyxFe2-y and piezoelectric Pb(Zr,Ti)O3 are quite sensitive to small dc magnetic field (Hdc) variations, when driven by a constant ac magnetic field. The sensitivity limit is Hdc<10-3 Oe (10-7...

    We analyze a pion form factor formulation which fulfills the Analyticity requirement within the redden Local Symmetry (HLS) Model. This implies an s-dependent dressing of the p - γ VMD coupling and an account of several coupled channels. The corresponding function Fπ (s) provides nice...
