چکیده
Quasiparticle thermal conductivity in the vortex state of high-T c cuprates. Abstract We present the results of a microscopic calculation of the longitudinal thermal conductivity, κ xx , of a d-wave superconductor in the mixed state. Our results show an increase in the thermal conductivity with the applied field at low temperatures, and a decrease followed by a nearly field independent κ xx (H) at higher temperatures, in qualitative agreement with the experimental results. We discuss the relationship between the slope of the superconducting gap and the plateau in κ xx (H).

The HQET/NRQCD Lagrangian is computed to order α/m3. The computation is performed using dimensional regularization to regulate the ultraviolet and infrared divergences. The results are consistent with reparametrization invariance to order 1/m3. Some subtleties in the matching conditions for NRQCD are discussed. Typeset using REVTEX 1
متن کاملInteresting Magnetic Properties of Fe 1−x Co X Si Alloys Typeset Using Revt E X
Solid solution between nonmagnetic narrow gap semiconductor FeSi and diamagnetic semi-metal CoSi gives rise to interesting metallic alloys with longrange helical magnetic ordering, for a wide range of intermediate concentration. We report various interesting magnetic properties of these alloys, including low temperature re-entrant spin-glass like behaviour and a novel inverted magnetic hysteres...
متن کاملProbing the Qcd Pomeron in E + E Collisions Typeset Using Revt E X
The total cross section for scattering virtual photons at high energy is sensitive to pomeron physics. If the photons are su ciently virtual, QCD perturbation theory applies, so that the reaction probes the short distance pomeron. We study this reaction for present and future e e colliders.

The paper entitled \Against Many-Worlds Interpretations" by A. Kent, which has recently been submitted to the e-Print archive (gr-qc/9703089) contained some misconceptions. The claims on Everett's many-worlds interpretation are quoted and answered.
متن کاملEecient Determination of Nonlinear Burnett Coeecients Typeset Using Revt E X
In a previous paper Phys. Rev. A 41, 4501 (1990)], simple equilibrium expressions were obtained for nonlinear Burnett coeecients. In this paper, we devise a more eecient way of using these expressions, and show some preliminary results from a colour conductivity simulation.
