Vortex pairs in rotatingA3in a tilted magnetic field

Abstract

We extend our analysis of Seppaaumllaauml-Volovik vortices in rotating ${}_{}{}^3{}_{}{}^{}\mathit{A}$ in a high magnetic field to the configuration where the magnetic field is tilted from the rotation axis. We find that the distance between vortices in a vortex pair decreases as the tilting angle increases from 0 to π/2. While the transverse NMR satellite frequency is quite insensitive to tilting except at lower temperature, the intensity of the resonance increases by almost 30% when ${\theta }_0$=π/2 compared to that for ${\theta }_0$=0 (${\theta }_0$ is the tilting angle) at T/$T_c$≃0.75. This is quite consistent with the recent experimental result of Seppaaumllaauml et al.
