Terahertz magneto-optical spectroscopy of two-dimensional hole and electron systems
N. Kamaraju, W. Pan, U. Ekenberg +6
We have used terahertz (THz) magneto-optical spectroscopy to investigate the cyclotron resonance in high mobility two-dimensional electron and hole systems. Our experiments reveal…
Analytical Comparison of Noise Reduction Filters for Image Restoration Using SNR Estimation
Poorna Banerjee Dasgupta
Noise removal from images is a part of image restoration in which we try to reconstruct or recover an image that has been degraded by using apriori knowledge of the degradation phe…
Discovery of a Quasi-Periodic Oscillation in the Ultraluminous X-ray Source IC 342 X-1: XMM-Newton Results
V. K. Agrawal, Anuj Nandi
We report the discovery of a quasi-periodic oscillation (QPO) at 642 mHz in an {\it XMM-Newton} observation of the ultraluminous X-ray source (ULX) IC 342 X-1. The QPO has a centro…
Periodic massloss from viscous accretion flows around black holes
Santabrata Das, Indranil Chattopadhyay, Anuj Nandi +1
We investigate the behaviour of low angular momentum viscous accretion flows around black holes using Smooth Particle Hydrodynamics (SPH) method. Earlier, it has been observed that…
Critical coupling and coherent perfect absorption for ranges of energies due to a complex gain and loss symmetric system
Mohammad Hasan, Ananya Ghatak, Bhabani Prasad Mandal
We consider a non-Hermitian medium with a gain and loss symmetric, exponentially damped potential distribution to demonstrate different scattering features analytically. The condit…
