Lie Symmetry Analysis and Some New Exact Solutions to the KP-BBM Equation
Arindam Ghosh, Sarit Maitra
This paper is aimed to study the KP-BBM equation, which was proposed by Abdul Majid Wazwaz in 2005. To check its integrability Painleve test has been performed. Lie Symmetry analys…
Non-uniform magnetic field as a booster for quantum speed limit: faster quantum information processing
Srishty Aggarwal, Subhashish Banerjee, Arindam Ghosh +1
We probe the quantum speed limit (QSL) of an electron when it is trapped in a non-uniform magnetic field. We show that the QSL increases to a large value, but within the regime of…
Exact Solutions and Symmetry Analysis of a Boussinesq type Equation for Longitudinal Waves through a Magneto-Electro-Elastic Circular Rod
Arindam Ghosh, Sarit Maitra, Asesh Roy Chowdhury
In this work the longitudinal wave equation through magneto-electro-elastic circular rod is studied analytically. Painlevé test is performed to check integrability of the equation.…
Signature of Two-Component Advective Flow in several Black Hole candidates obtained through time-of-arrival analysis of RXTE/ASM Data
Arindam Ghosh, Sandip K. Chakrabarti
We study several Galactic black hole candidates using long-time RXTE/ASM X-ray data to search for telltale signatures of differences in viscous timescales in the two components use…
Anomalous Outbursts of H 1743-322
Arindam Ghosh, Sandip K. Chakrabarti
Using black body and power-law photon counts of All Sky Monitor (ASM) in Rossi X-ray Timing Explorer (RXTE) satellite it has been established recently by us that there is a signifi…
Does Cyg X-1 have a small Standard Accretion Disc?
Arindam Ghosh, Indrani Banerjee, Sandip K. Chakrabarti
We analyze several outbursts of a few transient sources using Proportional Counter Array (PCA) data (2.5-25 keV) as well as All Sky Monitor (ASM) data (1.5-12 keV) of Rossi X-ray T…
Smearing of mass accretion rate variation by viscous processes in accretion disks in compact binary systems
Arindam Ghosh, Sandip Kumar Chakrabarti
Variation of mass supply rate from the companion can be smeared out by viscous processes inside an accretion disk. By the time the flow reaches the inner edge, the variation in X-r…
Periods of two enigmatic black hole candidates GRS 1915+105 and IGR J17091-3624
Arindam Ghosh, S. K. Chakrabarti
Galactic black hole candidates GRS 1915+105 and IGR J17091-3624 have many similarities in their light curves and spectral properties. However, very little is known about the orbita…
Periodic X-ray Modulation and its relation with orbital elements in Compact Binaries
Arindam Ghosh, Sandip K. Chakrabarti
Stellar companion of a black hole orbiting in an eccentric orbit will experience modulating tidal force with a periodicity same as that of the orbital period. This, in turn, would…
