Abstract

In finite magnetic field H, the excitation spectrum of the low energy quasiparticles in a two-dimensional d-wave superconductor exhibits a scaling with respect to H1/2. This property can be used to calculate scaling relations for various physical quantities at low temperature T, such as the finite magnetic field specific heat, quasiparticle magnetic susceptibility, optical conductivity tensor, and thermal conductivity tensor. These predictions are compatible with existing experimental data. Most notably, the measured thermal Hall coefficient κxy in YBCO is found to scale as κxy∼T2F(αT/H1/2) for T≲30K in agreement with our predictions.
