    • We here use a classical force law in which the quasiparticle group velocity vg =d Ek /dk couples to B, which also follows from a straightforward replacement k→k-eA in the spectral function appearing in the tunneling current. An alternative coupling [used in Ref., see also Ref.)], is obtained by making the replacement as follows: Ek-eA →√ ξ k-eA 2 + Δk2 so that the Lorentz force term is e vb ×B with vb = ( ξk / Ek ) d ξk /dk. As long as the magnitude of the pseudogap is small compared to the Fermi energy, the choice of vg versus vb makes little difference to interlayer current calculation with θB =π/2.

    • note
    • In constructing the plots of Fig., we have not taken into account any potential field dependence of the magnitude of the pseudogap. One can interpret Δ 0 as the value of the pseudogap in the presence of a certain field B, the magnitude of which is parameterized by ω C τ, and in this way allow for some B dependence of Δ 0 within these plots. In Ref., an applied field of 60 T results in a reduction in the pseudogap (defined via T -dependent interlayer resistivity data) in slightly overdoped BSCCO by less than 30% from its zero-field value. On the other hand, fields of 50 T are sufficient, according to Ref., to achieve values of ω C τ 0.5 in clean T 2201 samples. It would thus appear that the field dependence of ω C τ, and not that of Δ 0, would be most important in controlling the behavior of the interlayer resistivity over the parameter ranges considered in Fig.. So, while a field-dependent Δ 0 could be included for quantitative analysis, it is not expected to alter the qualitative picture described above.
