Reciprocity in parity violating non-Hermitian systems
Ananya Ghatak, Brijesh Kumar Mourya, Raka Dona Ray Mandal +1
Reciprocity is shown so far only when the scattering potential is either real or parity symmetric complex. We extend this result for parity violating complex potential by consideri…
Various Scattering Properties of a New PT-symmetric non-Hermitian potential
Ananya Ghatak, Raka Dona Ray Mandal, Bhabani Prasad Mandal
We complexify a 1-d potential which exhibits bound, reflecting and free states to study various properties of a non-Hermitian system. This potential turns out a PT-symmetric non-He…
The micro-glitch in PSR B1821-24 : A case for a strange pulsar?
Raka Dona Ray Mandal, Sushan Konar, Mira Dey +1
The single glitch observed in PSR B1821-24, a millisecond pulsar in M28, is unusual on two counts. First, the magnitude of this glitch is at least an order of magnitude smaller ($Δ…
Strange Pulsar Hypothesis
Raka Dona Ray Mandal, Monika Sinha, Manjari Bagchi +3
It appears that there is a genuine shortage of radio pulsars with surface magnetic fields significantly smaller than Gauss. We propose that the pulsars with very low ma…
