  • Hati, Chandan; Deppisch, Frank F.; Patra, Sudhanwa; Sarkar, Utpal; Valle, Jose W. F. (Elsevier, 2016-11)
    We consider the possibility of grand unification of the SU(3)c⊗SU(3)L⊗U(1)X model in an SU(6) gauge unification group. Two possibilities arise. Unlike other conventional grand unified theories, in SU(6) one can embed the ...
  • Dey, Ujjal Kumar; Mohanty, Subhendra; Tomar, Gaurav (Elsevier, 2016-05)
    We explain the 750 GeV750 GeV diphoton resonance in the context of the dark left-right symmetric model. A global symmetry in this model, stabilizes the dark matter and ensures that the scalar couples dominantly to gluons ...
  • Ali, Ahmed Farag; Faizal, Mir; Majumder, Barun (IOP Science, 2015-01)
    We argue that the divergence in time for an asymptotic observer occurs because of specifying the position of the Horizon beyond the Planck scale. In fact, a similar divergence in time will also occur for an in-going observer ...
  • Suthar, Kuldeep; Roy, Arko; D. Angom (IOP Science, 2014-06)
    We examine the dynamics of a vortex dipole in the Bose–Einstein condensates of trapped dilute atomic gases at zero temperature in the presence of a Gaussian barrier potential. The density anisotropy induced by the barrier ...
  • Sengupta, Anand (IOP Science, 2015-03)
    The Advanced LIGO gravitational wave detectors are second-generation instruments designed and built for the two LIGO observatories in Hanford, WA and Livingston, LA, USA. The two instruments are identical in design, and ...
  • Aadhi, A.; Apurv Chaitanya, N.; Jabir, M. V.; Vaity, Pravin; Singh, R. P.; Samanta, Goutam Kumar (Nature publishing group, 2016-05)
    Airy beam, a non-diffracting waveform, has peculiar properties of self-healing and self-acceleration. Due to such unique properties, the Airy beam finds many applications including curved plasma wave-guiding, micro-particle ...
  • Aadhi, A.; Apurv Chaitanya, N.; Jabir, M. V.; Singh, Ravindra P.; Samanta, Goutam Kumar (Optics InfoBase, 2015)
    We report on experimental demonstration of an all-periodically poled, continuous-wave (CW), high-power, single-frequency, ultra-violet (UV) source. Based on internal second-harmonic-generation (SHG) of a CW singly resonant ...
  • Sengupta, Anand (IOP Publishing, 2018-02)
    We present the results of a search for long-duration gravitational wave transients in the data of the LIGO Hanford and LIGO Livingston second generation detectors between $ \newcommand{\OOneStart}{{\rm 12 ~September ~2015}} ...
  • Sengupta, Anand (American Physical Society, 2017-09)
    We report on an all-sky search for periodic gravitational waves in the frequency band 20475 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 spinning ...
  • Sengupta, Anand (American Physical Society, 2017-02)
    We present the results from an all-sky search for short-duration gravitational waves in the data of the first run of the Advanced LIGO detectors between September 2015 and January 2016. The search algorithms use minimal ...
  • Sengupta, Anand (IOP Science, 2014-04)
    We report on an all-sky search for periodic gravitational waves in the frequency range 50–1000 Hz with the first derivative of frequency in the range −8.9 × 10−10 Hz s−1 to zero in two years of data collected during LIGO's ...
  • Sengupta, Anand (IOP Science, 2016-02)
    The discovery of the gravitational-wave (GW) source GW150914 with the Advanced LIGO detectors provides the first observational evidence for the existence of binary black hole (BH) systems that inspiral and merge within the ...
  • Kumar, Girish; Mahajan, Namit (American Physical Society, 2016-03)
    We calculate the zeros of angular observables P?4 and P?5 of the angular distribution of 4-body decay B?K?(?K?)l+l? where LHCb, in its analysis of form-factor independent angular observables, has found deviations from the ...
  • Hati, Chandan; Kumar, Girish; Mahajan, Namit (Springer Berlin Heidelberg, 2016-01)
    Recent experimental results from the LHCb, BaBar and Belle collaborations on the semitauonic decays of B meson, B¯¯¯¯→D(∗)τν¯¯¯, showing a significant deviation from the Standard Model (SM), hint towards a new physics ...
  • Sengupta, Anand (Wiley-VCH Verlag, 2017-01)
    The first direct gravitational-wave detection was made by the Advanced Laser Interferometer Gravitational Wave Observatory on September 14, 2015. The GW150914 signal was strong enough to be apparent, without using any ...
  • Ghalsasi, Pallavi; Poswal, H. K.; Tripathi, Ravi; Garg, Nandini; Deo, M. N.; Sharma, Surinder M. (IOP Publishing, 2012)
    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. ...

  • Khanna, Sakshum; Marathey, Priyanka; Utsav; Chaliawala, Harsh; Mukhopadhyay, Indrajit (AIP Publishing, 2018-05)
    We present the studies on the structural properties of monolayer Bidisperse silica (SiO2) nanoparticles (BDS) on Silicon (Si-100) substrate using spin coating technique. The Bidisperse silica nanoparticle was synthesised ...
  • Sengupta, Anand (American Physical Society, 2016-10)
    The first observational run of the Advanced LIGO detectors, from September 12, 2015 to January 19, 2016, saw the first detections of gravitational waves from binary black hole mergers. In this paper, we present full results ...
  • Majumder, Barun (Springer Link, 2013-11)
    Here we study the effects of the Generalized Uncertainty Principle in the tunneling formalism for Hawking radiation to evaluate the quantum-corrected Hawking temperature and entropy for a Schwarzschild black hole. We compare ...
