  • Chakraborty, Kaustav; Deepthi, K. N.; Goswami, Srubabati (Elsevier, 2018-12)
    Neutrino oscillation physics has entered the precision era and the potential forthcoming experiments Hyper-Kamiokande (T2HK / T2HKK), Deep Under-ground Neutrino Experiment (DUNE) and The European Spallation Source ?-Beam ...
  • Fairoos, C.; Ghosh, Avirup; Sarkar, Sudipta (World Scientific, 2018-10)
    The evolution of the black-hole horizon can be effectively captured by a fictitious membrane fluid living on the stretched horizon. We show that the dynamics of this boundary matter arises from the invariance of the bulk ...
  • Sengupta, Anand (American Physical Society, 2018-10)
    On 17 August 2017, the LIGO and Virgo observatories made the first direct detection of gravitational waves from the coalescence of a neutron star binary system. The detection of this gravitational-wave signal, GW170817, ...
  • Ghosh, Snigdha; Chandra, Vinod (American Physical Society (AIP), 2018-10)
    The dilepton production rate in a hot QCD medium is studied within an effective description of the medium in the presence of a magnetic field. This could be done by obtaining the one-loop self-energy of the photon due to ...
  • Ghosh, Snigdha; Ghosh, Sabyasachi; Bhattacharyya, Sumana (American Physical Society (AIP), 2018-10)
    We explore some phenomenological issues during calculations of transport coefficients for hadronic matter, produced in the experiments of heavy ion collisions. Here, we use an ideal hadron resonance gas model to demonstrate ...
  • Mukherjee, Arghya; Ghosh, Snigdha; Mandal, Mahatsab; Sarkar, Sourav; Roy, Pradip (American Physical Society, 2018-09)
    The vacuum to nuclear matter phase transition is studied in the presence of a constant external background magnetic field with the mean-field approximation in the Walecka model. The anomalous nucleon magnetic moment is ...
  • Sahu, Lokesh K.; Tripathi, Nidhi; Sheel, Varun; Kajino, Mizuo; Deushi, Makoto; Yadav, Ravi; Nedelec, Philippe (Wiley, 2018-04)
    The present study investigates the impact of tropical cyclone (TC) Nilam on the vertical distribution of carbon monoxide (CO) over Chennai in southern India. Measurements of OZone and water vapour by Airbus In?service ...
  • Kaur, Navpreet; Baliyan, Kiran S. (EDP Sciences for European Southern Observatory, 2018-09)
    Blazars in outburst provide a unique opportunity to study their spectral behavior, correlated variations at different frequencies, and jet structure. An unprecedented flaring activity in FSRQ CTA 102, occuring from 2016 ...
  • Mishra, Akash; Chakraborty, Sumanta; Ghosh, Avirup; Sarkar, Sudipta (Springer, 2018-09)
    Physical process version of the first law of black hole mechanics relates the change in entropy of a perturbed Killing horizon, between two asymptotic cross sections, to the matter flow into the horizon. Here, we study the ...
  • Kaur, Navpreet (IOP Publishing, 2018-09)
    We present the results of our power spectral density analysis for the BL Lac object OJ\,287, utilizing the {\it Fermi}-LAT survey at high-energy ?-rays, {\it Swift}-XRT in X-rays, several ground-based telescopes and the ...

    In the recent past, measurements of ?8 from large scale structure observations have shown some discordance with its value obtained from Planck CMB within the ? CDM frame. This discordance naturally leads to a mismatch ...
  • Bai, Rukmani; Bandyopadhyay, Soumik; Pal, Sukla; Suthar, K.; Angom, D (American Physical Society, 2018-08)
    Quantum Hall (QH) states of two-dimensional (2D) single-layer optical lattices are examined using the Bose-Hubbard model (BHM) in the presence of an artificial gauge field. We study the QH states of both the homogeneous ...
  • Fairoos, C; Ghosh, Avirup; Sarkar, Sudipta (American Physical Society, 2018-07)
    We study the entropy evolution of black holes in Lovelock gravity by formulating a thermodynamic generalization of the null Raychaudhuri equation. We show that the similarity between the expressions of entropy change of ...
  • Dey, Krishna Kanti (Wiley, 2018-07)
    Collective and emergent behaviors of active colloidal assemblies provide useful insights into the statistical physics of out‐of‐equilibrium systems. Colloidal suspensions containing microscopic active swimmers have recently ...
  • Kaur, Navpreet; Baliyan, Kiran S.; Chandra, S.; Sameer; Ganesh, S. (American Astronomical Society, 2018-07)
    With an aim to explore optical variability at diverse timescales in BL Lac source S5 0716+714, it was observed for 46 nights during 2013 January 14 to 2015 June 01 when it underwent two major outbursts. The observations ...

  • Bai, Rukmani; Roy, Arko; Angom, D.; Muruganandam, P. (Elsevier, 2018-06)
    We demonstrate an enhancement in the vortex generation when artificial gauge potential is introduced to condensates confined in a double well potential. This is due to the lower energy required to create a vortex in the ...
  • Chauhan, Bhavesh (American Physical Society, 2018-06)
    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 ...

    The bulk viscosity of hot QCD medium has been obtained in the presence of strong magnetic field. The present investigation involves the estimation of the quark damping rate and subsequently the thermal relaxation time for ...
