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…
Analyzing intramolecular vibrational energy redistribution via the overlap intensity-level velocity correlator
Srihari Keshavamurthy, Nicholas R. Cerruti, Steven Tomsovic
Numerous experimental and theoretical studies have established that intramolecular vibrational energy redistribution (IVR) in isolated molecules has a heirarchical tier structure.…
Sensitivity of Wave Field Evolution and Manifold Stability in Chaotic Systems
Nicholas R. Cerruti, Steven Tomsovic
The sensitivity of a wave field's evolution to small perturbations is of fundamental interest. For chaotic systems, there are two distinct regimes of either exponential or Gaussian…
Exploring phase space localization of chaotic eigenstates via parametric variation
Nicholas R. Cerruti, Arul Lakshminarayan, Julie H. Lefebvre +1
In a previous Letter [Phys. Rev. Lett. 77, 4158 (1996)], a new correlation measure was introduced that sensitively probes phase space localization properties of eigenstates. It is…
