Hadley | supr-con cond-mat.supr-con | https://arxiv.org/abs/supr-con/9607002 | 2009-10-30 | A theoretical model of high-T_c Josephson Field Effect Transistors (JoFETs) based on a Ginzburg-Landau free energy expression whose parameters are field- and spatially- dependent is developed. This model is used to explain experimental data on JoFETs made by the hole-overdoped Ca-SBCO bicrystal junctions (three termina... |
supr-con/9607003 | Flux flow resistivity and vortex viscosity of high-Tc films | J. I. Martin, M. Velez, F. Guinea and J. L. Vicent | supr-con cond-mat.supr-con | https://arxiv.org/abs/supr-con/9607003 | 2009-10-30 | The flux flow regime of high-T$_{\rm c}$ samples of different normal state resistivities is studied in the temperature range where the sign of the Hall effect is reversed. The scaling of the vortex viscosity with normal state resistivity is consistent with the Bardeen-Stephen theory. Estimates of the influence of possi... |
supr-con/9607004 | Comments on "Vortex Glass and Lattice Melting Transitions in a YNi_2B_2C Single Crystal" | S. Sridhar, S. Oxx, B.A. Willemsen, H. Srikanth, and D.P. Choudhury (Physics Department, Northeastern University) | supr-con cond-mat.supr-con | https://arxiv.org/abs/supr-con/9607004 | 2009-10-30 | Recently, Mun et.al. (Phys. Rev. Lett., 76, 2790 (1996)) have published their results on single crystal YNi_2B_2C, claiming that their experimental observations can be explained in terms of formation of Vortex Glass and Lattice melting. Our experiments, carried out on samples obtained from the SAME source, reveal a muc... |

Blatter | supr-con cond-mat.supr-con | https://arxiv.org/abs/supr-con/9607006 | 2009-10-30 | We investigate numerically the dynamically generated plastic deformations of a 3D vortex lattice (VL) driven through a disorder potential with isolated, strong pinning centers (point-like or extended along the field direction). We find that the VL exhibits a very peculiar dynamical behavior in the plastic flow regime, ... |
supr-con/9607007 | Towards a Microscopic Theory for Metallic Heavy-Fermion Point Contacts | F. B. Anders and K. Gloos | supr-con cond-mat.supr-con | https://arxiv.org/abs/supr-con/9607007 | 2009-10-30 | The bias-dependent resistance R(V) of NS-junctions is calculated using the Keldysh formalism in all orders of the transfer matrix element. We present a compact and simple formula for the Andreev current, that results from the coupling of electrons and holes on the normal side via the anomalous Green's function on the s... |
supr-con/9608001 | Topology and Phase Transitions in the Little-Parks Experiment | Jorge Berger and Jacob Rubinstein (Technion) | supr-con cond-mat.supr-con quant-ph | https://arxiv.org/abs/supr-con/9608001 | 2008-02-03 | This is an analytic study of the problem of transitions between normal and superconducting phases for a sample which encloses a magnetic flux. A preliminary study of this problem, based on numerical minimization of the free energy for a particular form of the thickness of the sample, was published in Phys. Rev. Lett. {... |

Scalapino | supr-con cond-mat.supr-con | https://arxiv.org/abs/supr-con/9608002 | 2009-10-30 | Results of a calculation of the c-axis infrared conductivity sigma_c for a d_{x^2-y^2}-wave superconductor which include both elastic impurity and inelastic spin-fluctuation scattering are presented and compared with the ab-plane conductivity sigma_{ab} in the same model. In this model,the interlayer c-axis coupling is... |
supr-con/9608003 | Extended bound states and resonances of two fermions on a periodic lattice | A. S. Blaer (1), H. C. Ren (2), and O. Tchernyshyov (1) ((1) Columbia University, (2) Rockefeller University) | supr-con cond-mat.supr-con | https://arxiv.org/abs/supr-con/9608003 | 2009-10-30 | The high-$T_c$ cuprates are possible candidates for d-wave superconductivity, with the Cooper pair wave function belonging to a non-trivial irreducible representation of the lattice point group. We argue that this d-wave symmetry is related to a special form of the fermionic kinetic energy and does not require any nove... |

Johnson | supr-con cond-mat.supr-con | https://arxiv.org/abs/supr-con/9608004 | 2016-09-08 | We investigate de Haas-van Alphen (dHvA) oscillations in the mixed state of a type-II two-dimensional superconductor within a self-consistent Gor'kov perturbation scheme. Assuming that the order parameter forms a vortex lattice we can calculate the expansion coefficients exactly to any order. We have tested the results... |
supr-con/9608005 | Evidence for Quasiparticle Decay in Photoemission from Underdoped Cuprates | R. B. Laughlin (Stanford) | supr-con cond-mat.supr-con | https://arxiv.org/abs/supr-con/9608005 | 2009-10-30 | I argue that the ``gap'' recently observed at the Brillouin zone face of cuprate superconductors in photoemission by Marshall et al [Phys. Rev. Lett. 76, 4841 (1996)] and Ding et al [Nature 382, 54 (1996)] is evidence for the decay of the injected hole into a spinon-holon pair. |

Castle (Brock University, Canada) | supr-con cond-mat.supr-con | https://arxiv.org/abs/supr-con/9608006 | 2009-10-30 | The interlayer pair tunneling model of Anderson et al. is generalized to include the strong coupling effects associated with in-plane interactions. The equations for the superconducting transition temperature T_{c} are solved numerically for several models of electron-optical phonon coupling. The nonmagnetic in-plane i... |

Varlamov | supr-con cond-mat.supr-con | https://arxiv.org/abs/supr-con/9608007 | 2009-10-30 | We study the effect of fluctuations on the {\bf ac} conductivity of a layered superconductor both for $c$-axis and $ab$-plane electromagnetic wave polarizations. The fluctuation contributions of different physical nature and signs (paraconductivity, Maki-Thompson anomalous contribution, one-electron density of states r... |

Villard, G. Koren | supr-con cond-mat.supr-con | https://arxiv.org/abs/supr-con/9608008 | 2009-10-30 | We report on measurements of the angular dependence of the irreversibility temperature $T_{irr}(\theta) $ in $YBa_2Cu_3O_{7-\delta }$ thin films, defined by the onset of a third harmonic signal and measured by a miniature Hall probe. From the functional form of $T_{irr}(\theta)$ we conclude that the origin of the irrev... |

Sridhar (Physics Department, Northeastern University and Rome Laboratory, Hanscom AFB.) | supr-con cond-mat.supr-con | https://arxiv.org/abs/supr-con/9609001 | 2016-11-18 | The non-linear microwave surface impedance of patterned YBCO thin films, was measured using a suspended line resonator in the presence of a perpendicular DC magnetic field of magnitude comparable to that of the microwave field. Signature of the virgin state was found to be absent even for relatively low microwave power... |

Z_s(H) is shown to be a direct measure of the flux density B(H) enabling a very precise test of models of flux penetration. Three regimes of ... |

supr-con/9609004 | Ginzburg Landau theory for d-wave pairing and fourfold symmetric vortex core structure | Naoki Enomoto, Masanori Ichioka and Kazushige Machida (Okayama Univ.) | supr-con cond-mat.supr-con | https://arxiv.org/abs/supr-con/9609004 | 2009-10-30 | The Ginzburg Landau theory for d_{x^2-y^2}-wave superconductors is constructed, by starting from the Gor'kov equation with including correction terms up to the next order of ln(T_c/T). Some of the non-local correction terms are found to break the cylindrical symmetry and lead to the fourfold symmetric core structure, r... |
