Analytical perturbative approach to periodic orbits in the homogeneous quartic oscillator potential
M. Brack, S. N. Fedotkin, A. G. Magner +1
We present an analytical calculation of periodic orbits in the homogeneous quartic oscillator potential. Exploiting the properties of the periodic Lam{é} functions that describe th…

Semiclassical theory of spin-orbit interactions using spin coherent states
M. Pletyukhov, Ch. Amann, M. Mehta +1
We formulate a semiclassical theory for systems with spin-orbit interactions. Using spin coherent states, we start from the path integral in an extended phase space, formulate the…

Semiclassical trace formulae for systems with spin-orbit interactions: successes and limitations of present approaches
Ch. Amann, M. Brack
We discuss the semiclassical approaches for describing systems with spin-orbit interactions by Littlejohn and Flynn (1991, 1992), Frisk and Guhr (1993), and by Bolte and Keppeler (…
