Dust-Ion-Acoustic Waves in unmagnetized 4-component plasma
Anjana Sinha, Biswajit Sahu
A theoretical study is presented for the propagation of Dust Ion Acoustic Waves in an unmagnetized four-component plasma, consisting of Maxwellian negative ions, cold mobile positi…
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…
Spectral Singularity in confined PT symmetric optical potential
Anjana Sinha, R. Roychoudhury
We present an analytical study for the scattering amplitudes (Reflection and Transmission ), of the periodic symmetric optical potential $ V(x) = \displayst…
Scattering in a varying mass PT symmetric double heterojunction
Anjana Sinha, R. Roychoudhury
We observe that the reflection and transmission coefficients of a particle within a double, PT symmetric heterojunction with spatially varying mass, show interesting features, depe…
Classical Trajectories of the Continuum States of the symmetric Scarf II potential
Anjana Sinha
We apply the factorization technique developed by Kuru et. al. [Ann. Phys. {\bf 323} (2008) 413] to obtain the exact analytical classical trajectories and momenta of the continuum…
Scattering states of a particle, with position-dependent mass, in a symmetric heterojunction
Anjana Sinha
The study of a particle with position-dependent effective mass (pdem), within a double heterojunction is extended into the complex domain --- when the region within the heterojunct…
