Ocean acoustic wave propagation and ray method correspondence: internal wave fine structure
Katherine C. Hegewisch, Nicholas R. Cerruti, Steven Tomsovic
Acoustic wave fields propagating long ranges through the ocean are refracted by the inhomogeneities in the ocean's sound speed profile. Intuitively, for a given acoustic source fre…

Exploring classical phase space structures of nearly integrable and mixed quantum systems via parametric variation
Nicholas R. Cerruti, Srihari Keshavamurthy, Steven Tomsovic
The correlation between overlap intensities and level velocities has been introduced as a sensitive measure capable of revealing phase space localization. Previously applied to cha…

A Uniform Approximation for the Fidelity in Chaotic Systems
Nicholas R. Cerruti, Steven Tomsovic
In quantum/wave systems with chaotic classical analogs, wavefunctions evolve in highly complex, yet deterministic ways. A slight perturbation of the system, though, will cause the…
