Constructing Exactly Solvable Pseudo-hermitian Many-particle Quantum Systems by Isospectral Deformation
Pijush K. Ghosh
A class of non-Dirac-hermitian many-particle quantum systems admitting entirely real spectra and unitary time-evolution is presented. These quantum models are isospectral with Dira…
Magnetic and Electronic properties of Eu0.9Ca0.1BaCo2O5.5+? with the disparity of Oxygen Stoichiometry
Md. Motin Seikh, Asish K. Kundu, V. Caignaert +2
The effect of oxygen content on the magnetic and transport properties of the ferromagnetic Eu0.9Ca0.1BaCo2O5.5+δ has been carried out. Unlike the increase in TC with calcium conten…
The size of the longest filament in the Luminous Red Galaxy distribution
Biswajit Pandey, Gauri Kulkarni, Somnath Bharadwaj +1
Filaments are one of the most prominent features visible in the galaxy distribution. Considering the Luminous Red Galaxies (LRGs) in the Sloan Digital Sky Survey Data Release Seven…
Modulational instability of ion-acoustic wave packets in quantum pair-ion plasmas
A. P. Misra, N. K. Ghosh
Amplitude modulation of quantum ion-acoustic waves (QIAWs) in a quantum electron-pair-ion plasma is studied. It is shown that the quantum coupling parameter (being the ratio of…
Effect of time delay on the onset of synchronization of the stochastic Kuramoto model
Monoj Kumar Sen, Bidhan Chandra Bag, Karen G. Petrosyan +1
We consider the Kuramoto model of globally coupled phase oscillators with time-delayed interactions, that is subject to the Ornstein-Uhlenbeck (Gaussian) colored or the non-Gaussia…
Reputation-Based Attack-Resistant Cooperation Stimulation (RACS) For Mobile Ad hoc Networks
Anuradha Banerjee, Paramartha Dutta
In mobile ad hoc networks (MANET), nodes usually belong to different authorities and pursue different goals. In order to maximize their own performance, nodes in such networks tend…
