Fluctuation properties of strength function associated with the giant quadrupole resonance in 208Pb

Hirokazu Aiba, Masayuki Matsuo, Shigeru Nishizaki +1

We performed fluctuation analysis by means of the local scaling dimension for the strength function of the isoscalar (IS) giant quadrupole resonance (GQR) in 208Pb where the streng…

Nodal Domain Distribution for a Nonintegrable Two-Dimensional Anharmonic Oscillator

Hirokazu Aiba, Toru Suzuki

We investigate the transition from integrable to chaotic dynamics in the quantum mechanical wave functions from the point of view of the nodal structure by employing a two dimensio…

Fluctuation properties of strength functions associated with giant resonances

Hirokazu Aiba, Masayuki Matsuo, Shigeru Nishizaki +1

We performed fluctuation analysis by means of the local scaling dimension for the strength function of the isoscalar (IS) and the isovector (IV) giant quadrupole resonances (GQR) i…

Second moment of the Husimi distribution as a measure of complexity of quantum states

Ayumu Sugita, Hirokazu Aiba

We propose the second moment of the Husimi distribution as a measure of complexity of quantum states. The inverse of this quantity represents the effective volume in phase space oc…

Response Function of an Irregular Oscillator

Hirokazu Aiba, Toru Suzuki

Properties of the response functions for a two-dimensional quartic oscillator are studied based on the diagonalization of the Hamiltonian in a large model space. In particular, res…

Scaling Analysis of Fluctuating Strength Function

Hirokazu Aiba, Masayuki Matsuo

We propose a new method to analyze fluctuations in the strength function phenomena in highly excited nuclei. Extending the method of multifractal analysis to the cases where the st…
