Abstract

The quasiparticle contribution to the conductivity of a nearly superconducting two-dimensional Fermi liquid in a perpendicular magnetic field B is studied. The Boltzmann equation for the case of scattering on the pair fluctuations is shown to be the same as for forward scattering on a particle-hole collective mode. It is shown that in both cases, the Jones-Zener expansion of the conductivity tensor in powers of B is severely modified. Implications for some theories of the normal state in the cuprates and also for nearly ferromagnetic systems are discussed.
