Light scattering in Cooper-paired Fermi atoms
Bimalendu Deb
We present a detailed theoretical study of light scattering off superfluid trapped Fermi gas of atoms at zero temperature. We apply Nambu-Gorkov formalism of superconductivity to c…
Energy Centroids in the presence of random interactions
Y. M. Zhao, A. Arima, N. Yoshida +3
In this paper we study energy centroids such as those with fixed spin and isospin, those with fixed irreducible representations for bosons, in the presence of random two-body and/o…
Quantum spectrum as a time series : Fluctuation measures
M. S. Santhanam, Jayendra N. Bandyopadhyay, Dilip Angom
The fluctuations in the quantum spectrum could be treated like a time series. In this framework, we explore the statistical self-similarity in the quantum spectrum using the detren…
Intra-night Optical Variability of Luminous Radio Quiet QSOs
A. C. Gupta, U. C. Joshi
In the present paper we report the detection of intra-night variability in some of the RQQSOs and one LDQ. To study intra-night variability, we carried out photometric monitoring o…
Spectral fluctuations and 1/f noise in the order-chaos transition regime
M. S. Santhanam, Jayendra N. Bandyopadhyay
Level fluctuations in quantum system have been used to characterize quantum chaos using random matrix models. Recently time series methods were used to relate level fluctuations to…
