    On June 8, 2017 at 02:01:16.49 UTC, a gravitational-wave signal from the merger of two stellar-mass black holes was observed by the two Advanced LIGO detectors with a network signal-to-noise ratio of 13. This system is the ...
  • Singh, Balbeer; Thakur, Lata; Mishra, Hiranmaya (Cornell University Library, 2017-11)
    We study the effect of 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 lowest Landau level approximation. ...
  • Chauhan, Bhavesh (Cornell University Library, 2017-11)
    In this paper, we present a model for sub-MeV dark matter with strong self interactions which can solve some of the small scale crisis of the ?CDM. The dark matter is a Majorana fermion with only off-diagonal interactions ...
  • Mitra, Sukanya; Chandra, Vinod (American Physical Society, 2017-11)
    The main focus of this article is to obtain various transport coefficients for a hot QCD medium that is likely to be produced while colliding two heavy nuclei ultra-relativistically. The technical approach adopted here is ...
  • Sengupta, Anand (American Physical Society, 2017-09)
    We report on an all-sky search for periodic gravitational waves in the frequency band 20�475 Hz and with a frequency time derivative in the range of [?1.0,+0.1]�10?8??Hz/s. Such a signal could be produced by a nearby ...
  • Deepthi, K.?N.; Goswami, Srubabati; Nath, Newton (American Physical Society, 2017-10)
    We study the effect of nonstandard interactions (NSIs) on the propagation of neutrinos through the Earth�s matter and how it affects the hierarchy sensitivity of the DUNE experiment. We emphasize the special case when the ...
  • Fairoos, C.; Ghosh, Avirup; Sarkar, Sudipta (American Physical Society, 2017-10)
    The formulation of the laws of Black hole mechanics assumes the stability of black holes under perturbations in accordance with the �cosmic censorship hypothesis� (CCH). CCH prohibits the formation of a naked singularity ...
  • Sengupta, Anand (American Physical Society, 2015-01)
    In this paper we present the results of a coherent narrow-band search for continuous gravitational-wave signals from the Crab and Vela pulsars conducted on Virgo VSR4 data. In order to take into account a possible small ...
  • Apurv Chaitanya, N.; Jabir, M. V.; Banerji, J.; Samanta, G. K. (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, ...
  • Ghosh, Snigdha; Mitra, Sukanya; Sarkar, Sourav (Elsevier, 2017-10)
    The electromagnetic response of an interacting system of pions has been studied at finite temperature. The corresponding transport parameter i.e. electrical conductivity has been estimated by solving the relativistic ...
  • Sengupta, Anand (American Astronomical Society, 2017-06)
    On 2017 August 17, the gravitational-wave event GW170817 was observed by the Advanced LIGO and Virgo detectors, and the gamma-ray burst (GRB) GRB 170817A was observed independently by the Fermi Gamma-ray Burst Monitor, and ...
  • Sengupta, Anand (Cornell University Library, 2017-10)
    The first observation of a binary neutron star coalescence by the Advanced LIGO and Advanced Virgo gravitational-wave detectors offers an unprecedented opportunity to study matter under the most extreme conditions. After ...
  • Gupta, Toral; Majumder, Barun; Yagi, Kent; Yunes, Nicol�s (Cornell University Library, 2017-10)
    Neutron stars are ideal to probe, not only nuclear physics, but also strong-field gravity. Approximate universal relations insensitive to the star's internal structure exist among certain observables and are useful in ...
  • Bandyopadhyay, Soumik; Roy, Arko; Angom D. (American Physical Society, 2017-04-04)
    We examine the dynamics associated with the miscibility-immiscibility transition of trapped two-species Bose-Einstein condensates (TBECs) of dilute atomic gases in the presence of vortices. In particular, we consider TBECs ...
  • Ghosh, Snigdha; Mitra, Sukanya; Sarkar, Sourav (Elsevier B.V., 2018-02)
    The electromagnetic response of an interacting system of pions has been studied at finite temperature. The corresponding transport parameter i.e. electrical conductivity has been estimated by solving the relativistic ...
  • Dhuria, Mansi; Hati, Chandan; Rangarajan, Raghavan; Sarkar, Utpal (IOP Publishing, 2015-09)
    We review the non-supersymmetric (Extended) Left-Right Symmetric Models (LRSM) and low energy E6-based models to investigate if they can explain both the recently detected excess eejj signal at CMS and leptogenesis. The ...
  • Bhattacharjee, Srijit; Sarkar, Sudipta; Wall, Aron C. (American Physical Society, 2015-09)
    Standard methods for calculating the black hole entropy beyond general relativity are ambiguous when the horizon is nonstationary. We fix these ambiguities in all quadratic curvature gravity theories, by demanding that the ...
  • Ghalsasi, Pallavi; Poswal, H. K.; Tripathi, Ravi; Garg, Nandini; Deo, M. N.; Sharma, Surinder M. (IOP Publishing, 2012-07)
    Recent discovery of colossal negative thermal expansion (NTE) behaviour in Silver Hexacyanocobaltate Ag3[Co(CN)6] has triggered interest among researchers to understand the basic mechanism causing such an unusual behaviour. ...
  • Bhagwat, Ameeya A.; Viñas, X.; Centelles, M.; Schuck, P.; Wyss, R. (American Physical Society, 2010-04)
    The semiclassical Wigner-Kirkwood ℏ expansion method is used to calculate shell corrections for spherical and deformed nuclei. The expansion is carried out up to fourth order in ℏ. A systematic study of Wigner-Kirkwood ...

    One-Dimensional Fanno ow equations may be represented by the governing par- tial di erential equations for mass, momentum and energy conservation. The present study focuses on the numerical solution of one-dimensional ...
