Riemann surfaces of complex classical trajectories and tunnelling splitting in one-dimensional systems
Hiromitsu Harada, Amaury Mouchet, Akira Shudo
The topology of complex classical paths is investigated to discuss quantum tunnelling splittings in one-dimensional systems. Here the Hamiltonian is assumed to be given as polynomi…

Time dependent Pais-Uhlenbeck oscillator and its decomposition
H. Kuwabara, T. Yumibayashi, H. Harada
The Pais-Uhlenbeck(PU) oscillator is the simplest model with higher time derivatives. Its properties were studied for a long time. In this paper, we extend the 4th order free PU os…
