New Model and Numerical Test of a High Temperature Pairing Mechanism in Stripes
Oron Zachar
We introduce a new model and mechanism of high temperature pairing in stripes. We propose a way to unambiguously test it by numerical simulations. For example, the implementation o…
Numerical Test of the Energy Scale of Columnar Dimerization in High-T_{c} Cuperate Superconductors
Oron Zachar
Spontaneous bond dimerization (BD) was cojectured to be central to the physics of the cuperate superconductors. Based on ladder models and numerical simulations, we examine the qua…
Effect of magnetic field on over-doped HTc superconductors: Conflicting predictions of various HTc theories
Oron Zachar
Following the recent NMR experiments by Gorny et al., we discuss the effect of a magnetic field on the superconducting T_c and the spin pseudo-gap T^*. As a testable prediction, we…
Negative Josephson coupling in the Kondo strong coupling limit
Oron Zachar
We Show that pair hopping through a Kondo singlet give rise to a negative Josephson coupling. Thus, our calculation supports the existance of staggered pair correlations in the str…
