Sensitivity of quantum chaotic wavefunction intensities to changes in external perturbations
E. R. Mucciolo, B. D. Simons, A. V. Andreev +1
We examine the sensitivity of wavefunction intensities in chaotic quantum systems to small changes in an arbitrary external perturbation. A universal scaling is proposed for all th…

Crossover Driven by Time-reversal Symmetry Breaking in Quantum Chaos
N. Taniguchi, A. Hashimoto, B. D. Simons +1
Parametric correlations of energy spectra of quantum chaotic systems are presented in the orthogonal-unitary and symplectic-unitary crossover region. The spectra are allowed to dis…

Exact Dynamical Correlations of the 1/r^2 Model
E. R. Mucciolo, B. S. Shastry, B. D. Simons +1
We present exact results for the dynamical structure function, i.e.~the density-density correlations for the 1/r^2 system of interacting particles at three special values of the co…
