  • Vadawale, S. V.; Chattopadhyay, Tanmoy; Rao, A. R.; Bhattacharya, Debayan; Bhalerao, V. B.; Vagshette, N.; Pawar, P.; Sreekumar, S. (European Southern Observatory, 2015-06)
    X-ray polarimetry is largely an unexplored area of an otherwise mature field of X-ray astronomy. Except for a few early attempts during the 1970s, no dedicated X-ray polarimeter has been flown during the past four decades. ...
  • Singh, Balbeer; Thakur, Lata; Mishra, Hiranmaya (Cornell University Library, 2017-11)
    We study the effect of a strong constant magnetic field, generated in relativistic heavy ion collisions, on the heavy quark complex potential. We work in the strong magnetic field limit with the lowest Landau level ...

  • Singh, Balbeer; Abhishek, Aman; Das, Santosh K.; Mishra, Hiranmaya, (Cornell University Library, 2018-12)
    We calculate the transport coefficients, drag and momentum diffusion, of a heavy quark in a thermalised plasma of light quarks in the background of Polyakov loop. Quark thermal mass and the gluon Debye mass are calculated ...
  • Kurian, Manu; Das, Santosh K.; Chandra, Vinod (Cornell University Library, 2019-07)
    The heavy quark drag and momentum diffusion have been investigated in a hot magnetized quark-gluon plasma, along the directions parallel and perpendicular to the magnetic field. The analysis is done within the framework ...

  • Singh, Balbeer; Mishra, Hiranmaya (Cornell University Library, 2019-11)
    We study the effect of shear and bulk viscosities on the heavy quark transport coefficient within the matrix model of semi QGP. Dissipative effects are incorporated through the first-order viscous correction in the ...
  • Bhattacharya, Kaushik; Chakrabortty, Joydeep; Das, Suratna; Mondal, Tanmoy (IOP Science, 2014-12)
    If the recent detection of B-mode polarization of the Cosmic Microwave Background by BICEP2 observations, withstand the test of time after the release of recent PLANCK dust polarisation data, then it would surprisingly put ...
  • Bhattacharya, Kaushik; Chakrabortty, Joydeep; Das, Suratna; Mondal, Tanmoy (Cornell University Library, 2014-08)
    Recent detection of B−mode polarization of the Cosmic Microwave Background by BICEP2 observations has surprisingly put the inflationary scale near Grand Unification scale if one considers single-field inflationary models. ...
  • Sengupta, Anand; Gaur, G. (American Physical Society, 2016-06)
    We present the high-energy-neutrino follow-up observations of the first gravitational wave transient GW150914 observed by the Advanced LIGO detectors on September 14, 2015. We search for coincident neutrino candidates ...
  • Aadhi, A.; Apurv Chaitanya, N.; Singh, Ravindra P.; Samanta, Goutam Kumar (Optical Society of America, 2014-06)
    We report the development of a compact, high-power, continuous-wave, single-frequency, ultraviolet (UV) source with extended wavelength tunability. The device is based on single-pass, intracavity, second-harmonic-generation ...
  • Aadhi, A.; Vaity, Pravin; Apurv Chaitanya, N.; Jabir, M. V.; Singh, Ravindra P.; Samanta, Goutam Kumar (OSA Publishing, 2015-05-10)
    We demonstrate a new class of optical parametric oscillators producing high-power, output beam in 2-D Airy intensity profile. The Airy beam has output power >8W, longest ever acceleration length (>2m), and wavelength ...
  • Aadhi, A.; Vaity, Pravin; Apurv Chaitanya, N.; Jabir, M. V.; Singh, R. P.; Samanta, Goutam Kumar (2016-01-05)
  • Apurv Chaitanya, N.; Aadhi, A.; Jabir, M. V.; Samanta, Goutam Kumar (OSA Publishing, 2015-09)
    We report on the development of a high-power, high-repetition-rate, fiber laser based source of ultrafast ultraviolet (UV) radiation. Using single-pass second-harmonic generation and subsequent sum-frequency generation ...
  • C., Fairoos; Sarkar, Sudipta; Yogendran, K. P. (Cornell University Library, 2017-03)
    The purely thermal nature of Hawking radiation from evaporating black holes leads to the information loss paradox. A possible route to its resolution could be if (enough) correlations are shown to be present in the radiation ...
  • Apurv Chaitanya, N.; Jabir, M. V.; Banerji, Jagannath; Samanta, Goutam Kumar (Nature Publishing Group, 2016-09)
    Hollow Gaussian beams (HGB) are a special class of doughnut shaped beams that do not carry orbital angular momentum (OAM). Such beams have a wide range of applications in many fields including atomic optics, bio-photonics, ...

  • Bhattacharjee, Srijit; Sarkar, Sudipta; Wall, Aron C. (Cornell University Library, 2015-04)
    Standard methods for calculating the black hole entropy beyond general relativity are ambiguous when the horizon is non stationary. We fix these ambiguities in all quadratic curvature gravity theories, by demanding that ...
