Controlling pulse propagation in optical fibers through nonlinearity and dispersion management
Rajneesh Atre, Prasanta K. Panigrahi
In case of the nonlinear Schrödinger equation with designed group velocity dispersion, variable nonlinearity and gain/loss; we analytically demonstrate the phenomenon of chirp reve…
The Fe-Line Feature In The X-Ray Spectrum of Solar Flares: First Results From The SOXS Mission
Rajmal Jain, Anil K. Pradhan, Vishal Joshi +5
We present the first results from the "Low Energy Detector" payload of the "Solar X-ray Spectrometer (SOXS)" mission, which was launched onboard the GSAT-2 Indian spacecraft on 08…
Gravitational Leptogenesis
Gaetano Lambiase, Subhendra Mohanty
We introduce a dimension five CP violating coupling between the Ricci scalar and fermions. This operator splits the energy level between neutrinos and anti-neutrinos and can genera…
Neutrino Phenomenology, Dark Energy and Leptogenesis from pseudo-Nambu-Goldstone Bosons
C. T. Hill, I. Mocioiu, E. A. Paschos +1
We consider a model of dynamical neutrino masses via the see-saw mechanism. Nambu-Goldstone bosons (majorons) arise associated with the formation of the heavy right-handed majorana…
Low-Energy Thermal Leptogenesis in an Extended NMSSM Model
Ernest Ma, Narendra Sahu, Utpal Sarkar
Thermal leptogenesis in the canonical seesaw model in supersymmetry suffers from the incompatibility of a generic lower bound on the mass scale of the lightest right-handed neutrin…
A near-infrared shock wave in the 2006 outburst of recurrent nova RS Ophiuchi
Ramkrishna Das, Dipankar P. K. Banerjee, Nagarhalli M. Ashok
Near-infrared spectra are presented for the recent 2006 outburst of the recurrent nova RS Ophiuchi (RS Oph).We report the rare detection of an infrared shock wave as the nova eject…
