The Accretion History of AGN: The Spectral Energy Distributions of X-ray Luminous AGN
Connor Auge, David Sanders, Ezequiel Treister +17
Spectral energy distributions (SEDs) from X-ray to far-infrared (FIR) wavelengths are presented for a sample of 1246 X-ray luminous active galactic nuclei (AGN; $L_{0.5-10\rm{keV}}…
Statistical ensembles and logarithmic corrections to black hole entropy
Aritra Ghosh
In this paper, we consider general statistical ensembles and compute logarithmic corrections to the microcanonical entropy resulting due to thermodynamic fluctuations which are con…
Jacobi last multiplier and two-dimensional superintegrable oscillators
Akash Sinha, Aritra Ghosh
In this paper, we examine the role of the Jacobi last multiplier in the context of two-dimensional oscillators. We first consider two-dimensional unit-mass oscillators admitting a…
Independent-oscillator model and the quantum Langevin equation for an oscillator: A review
Aritra Ghosh, Malay Bandyopadhyay, Sushanta Dattagupta +1
This review provides a brief and quick introduction to the quantum Langevin equation for an oscillator, while focusing on the steady-state thermodynamic aspects. A derivation of th…
Dynamical symmetries of the anisotropic oscillator
Akash Sinha, Aritra Ghosh, Bijan Bagchi
It is well known that the Hamiltonian of an -dimensional isotropic oscillator admits an symmetry, making the system maximally superintegrable. However, the dynamical sym…
Dynamical symmetries of supersymmetric oscillators
Akash Sinha, Aritra Ghosh, Bijan Bagchi
In this paper, we describe the dynamical symmetries of classical supersymmetric oscillators in one and two spatial (bosonic) dimensions. Our main ingredient is a generalized Poisso…
