✦ Synopsis

The superconducting state of the cuprates in the presence of a magnetic 5eld has been investigated very actively in the past few years through measurements of electrical and thermal transport, ac conductivity, speci5c heat, and other quantities. The observed behavior is not well understood; it probes the nature of quasiparticles, vortices, and their interactions in a superconductor with nodes in the pair amplitude. We summarize here experimental results and our attempts to understand the phenomena.

The local density of states of low energy electronic excitations in a vortex is investigated. Starting from the Bogoliubov Hamiltonian, we make the approximation of replacing the quadratic momentum dependence of the free particle kinetic energy by a linear dependence. We then work with a linearized
