Spin phase-space semiclassics for weak spin-orbit coupling

Abstract

We apply the semiclassical spin coherent state method for the density of states by Pletyukhov et al (2002 Phys. Rev. Lett. 89 116601) in the weak spin–orbit coupling limit and recover the modulation factor in the semiclassical trace formula found by Bolte and Keppeler (1998 Phys. Rev. Lett. 81 1987; 1999 Ann. Phys., NY 274 125).
