D-XY Critical Behavior in Cuprate Superconductors
T. Schneider, J. M. Singer
We outline the universal and finite temperature critical properties of the 3D-XY model, extended to anisotropic extreme type-II superconductors, as well as the universal quantum cr…
Torque magnetometry on single-crystal high temperature superconductors near the critical temperature: a scaling approach
J. Hofer, T. Schneider, J. M. Singer +6
Angular-dependent magnetic torque measurements performed near the critical temperature on single crystals of HgBa_{2}CuO_{4+y}, La_{2-x}Sr{x}CuO_{4}, and YBa_{2}Cu_{3}O_{6.93} are…
2D scaling approach for the first order transition in Bi_2Sr_2CaCu_2O_{8+y}
T. Schneider, J. M. Singer
We analyze recent measurements by Ooi et al. of the angular dependence of the first order vortex phase transition in Bi_2Sr_2CaCu_2O_{8+y}. The experimental findings of these autho…
Finite size effect in the specific heat of YBa2Cu3O7-delta
T. Schneider, J. M. Singer
We analyze high precision, high resolution microcalorimetric specific heat data of detwinned YBa2Cu3O(7-delta) single crystals. It is shown that a finite size effect must be taken…
Magnetic Field Induced Phase Transitions in YBa2Cu4O8
T. Schneider, J. M. Singer
The -axis resistivity measurements in YBa_2Cu_4O_8 from Hussey et al. for magnetic field orientations along the c-axis as well as within the ab-plane are analyzed and interprete…
Magnetic Field induced Dimensional Crossover Phenomena in Cuprate Superconductors and their Implications
T. Schneider, J. M. Singer
We discuss the occurrence of crossing points in the magnetization - temperature ) plane within the framework of critical phenomena. It is shown that in a two-dimensional supe…
Fundamental constraints for the mechanism of superconductivity in cuprates
T. Schneider, J. M. Singer
Considerable progress has been made over the last decade in understanding the phenomenological properties of the cuprate high-T superconductors and in producing well characte…
Quantum Monte Carlo Evidence for d-wave Pairing in the 2D Hubbard Model at a van Hove Singularity
T. Husslein, I. Morgenstern, D. M. Newns +3
We implement a Quantum Monte Carlo calculation for a repulsive Hubbard model with nearest and next-nearest neighbor hopping interactions on clusters up to 12x12. A parameter region…
