Dissipative nonlinear waves in a gravitating quantum fluid
Biswajit Sahu, Anjana Sinha, R. Roychoudhury
Nonlinear wave propagation is studied analytically in a dissipative, self-gravitating Bose Einstein condensate, in the framework of Gross-Pitaevskii model. The linear dispersion re…

Structural, optical and complex impedance spectroscopy study of multiferroic Bi2Fe4O9 ceramic
S. R. Mohapatra, B. Sahu, T. Badapanda +3
Multiferroic bismuth ferrite Bi_2Fe_4O_9 (BFO) ceramic was synthesized by conventional solid state reaction route. X-ray diffraction and Rietveld refinement show formation of singl…
