"The tendency of modern physics is to resolve the whole material universe into waves, and nothing but waves.
These waves are of two kinds: bottled-up waves, which we call matter, and unbottled waves, which we call radiation or light...."

  • Coherence and Quantum Entanglement, Supervisor - Prof. Anand Kumar Jha (Visit Website)
    My resaerch area involves studying both theoritical and experimental aspects of multi-photon high-dimensional quantum entanglement as well as application of it in development of quantum technology. Our main objectives are, (1) developing an efficient detector for measuring high-dimensional entangled state for applications in quantum sensing and metrology; (2) investigating multi-photon interference and coherence properties for quantum metrology; (3) exploring the photon statistics of entangled photons.

  • Probing Turbulence in the Interstellar Medium of MilkyWay Galaxy, Supervisor - Dr. Prasun Dutta
    In this thesis, we use HI4PI data to probe turbulence in the interstellar medium of the Milky Way Galaxy using neutral hydrogen (H I) 21-cm emission. Here we have explored the physical aspects of the interstellar medium in our galaxy and tried to understand the role of fluid turbulence in it. The ISM of our galaxy consists of lots of dense filamentary and sheet like structures. Here we want to probe the HI medium without these densed structures, thus we have detected the filaments and choose the off filament region to check for velocity channel averaging (VCA). In this work, our result indicates the presence of velocity modification upto a certain scale unlike the previous results. Bimodality characteristics in the orientation of the filaments and qudrupole moment dominated anistropic intersteller medium arise more curosity to find for the causes of these observational results.

  • Study of frequency-dependent eclipsing for PSR J2051-0827 with uGMRT, Supervisor - Dr. Bhaswati Bhattacharyya
    In this research project, we have presented the frequency dependent eclipsing study for a black widow millisecond pulsar J2051-0827. From the simultaneous dual frequency wide band observation with uGMRT we have observed eclipse at Band 4 and no eclipse at Band 5 at the eclipse phase of Band 4. Frequency dependent study of eclipsing allowed us to decide the onset frequency for this BW MSP 4 times more precise than previously known. With the help of the pulsar timing we have checked for excess electron column density variation with the orbital phase which has showed excess electron column density at eclipse phase than the non eclipse phase. On the basis of these studies we have commented that refraction and pulse smearing should not be the probable eclipse mechanisms for J2051-0827, scattering effect may be present and there is lack of cyclotron absorption at >637 MHz frequency.

  • Studying the corona of solar-type stars using XMM-NEWTON data
    Using data reduction techniques we found out the image , spectra and light curve of an eclipsing binary of two solar type stars i.e. of DV Psc. As the result of these light curve and spectrum analysis we found that there are two flaring events in this system. Spectra indicated that it is thermal bremsstrahlung radiation and we fitted the spectra for quiescent state of the star and results shows that quiescent state of DV Psc consists of two temperature plasma with cool and hot temperature components of 0.26 and 1 keV.
