  • Lal, Nijil; Chithrabhanu, P.; Gangi Reddy, Salla; Anwar, Ali; Aadhi, A.; Singh, R. P. (Optical Society of America, 2016)
    We generate the non-separable state of polarization and orbital angular momentum using a laser beam. The generated state undergoes a cyclic polarization evolution which introduces a Pancharatnam geometric phase to the ...
  • Bhattacharya, Aranya; Bhattacharyya, Arpan; Nandy, Pratik; Patra, Ayan K. (Springer, 2021-12)
    We compute the holographic subregion complexity of a radiation subsystem in a geometric secret-sharing model of Hawking radiation in the "complexity = volume" proposal. The model is constructed using multiboundary wormhole ...
  • Kalon, Gopinadhan (Springer Nature, 2019-12)
    Defect-free monolayers of graphene and hexagonal boron nitride are surprisingly permeable to thermal protons, despite being completely impenetrable to all gases. It remains untested whether small ions can permeate through ...
  • Majumder, Barun; Farag Ali, Ahmed; Gubitosi, Giulia; Faizal, Mir (Hindawi Publishing Corporation, 2017-01)
  • 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 ...
  • Nath, Newton; Ghosh, Monojit; Goswami, Srubabati; Gupta, Shivani (Springer Verlag, 2017-03)
    We study the zero textures of the Yukawa matrices in the minimal extended type-I seesaw (MES) model which can give rise to ∼ eV scale sterile neutrinos. In this model, three right handed neutrinos and one extra singlet S ...
  • Bansal, Anshika; Mahajan, Namit (American Physical Society, 2021-03)
    We present the study of radiative tau decay ( τ − → π − ν τ γ ), computing the structure dependent contribution using light cone sum rules. This decay includes the same form factors as the radiative pion decay with the ...
  • Lal, Nijil; Banerji, Anindya; Biswas, Ayan; Anwar, Ali; Singh, R. P. (Taylor & Francis, 2019-12)
    We study the correlation properties of single photons carrying orbital angular momentum (OAM) in a Hanbury Brown and Twiss (HBT) type experiment. We have characterized single photon sources obtained by pumping a nonlinear ...
  • Bhattacharjee, Srijit; Sarkar, Sudipta (American Physical Society, 2015-01)
    We study the perturbation induced by a slowly rotating massive object as it passes through a Rindler horizon. It is shown that the passage of this object can be approximately modeled as delta function type tidal distortions ...
  • Roy, Soumen; Sengupta, Anand S. et al. (IOP Publishing, 2021-05)
    We report on the population of 47 compact binary mergers detected with a false-alarm rate of <$1\,{\mathrm{yr}}^{-1}$ in the second LIGO–Virgo Gravitational-Wave Transient Catalog. We observe several characteristics of the ...
  • Ali, Tibra; Bhattacharyya, Arpan; Shajidul Haque, S.; Kim, Eugene H.; Moynihan, Nathan (Elsevier, 2020-12)
    We investigate the evolution of complexity and entanglement following a quench in a one-dimensional topological system, namely the Su-Schrieffer-Heeger model. We demonstrate that complexity can detect quantum phase transitions ...
  • Masoodia, Ather; Sengupta, Anand; Khana, Fareed A.; Sharma, Gyan P. (Elsevier, 2013-08)
    Alligator weed (Alternanthera philoxeroides) is an amphibious weed invading worldwide. It was reported very recently from Wular lake, a Ramsar site in India. The weed forms isolated floating islands of variable sizes in ...
  • Bhattacharya, Sukannya; Mohanty, Subhendra; Parashari, Priyank (American Physical Society, 2020-08)
    For primordial black holes (PBHs) to form a considerable fraction of cold dark matter, the required amplitude of primordial scalar perturbations is quite large (P?(k)?10?2) if PBH is formed in radiation epoch. In alternate ...
  • Bhatt, Jitesh R.; Pandey, Arun Kumar (American Physical Society, 2016-08)
    We study the generation of a magnetic field in primordial plasma of standard model particles at a temperature T>80  TeV—much higher than the electroweak scale. It is assumed that there is an excess number of right-handed ...
  • Bhadari, Naval Kishor; Dewangan, L. K.; Zemlyanukha, P. M.; Ojha, D. K.; Zinchenko, I. I.; Sharma, Saurabh (IOP Publishing, 2021-12)
    We report an observational study of the Galactic H ii region Sh 2-305/S305 using the [C ii] 158 ?m line data, which are used to examine the gas dynamics and structure of photodissociation regions. The integrated [C ii] ...
  • Jana, Arghajit; Chatterjee, Arka; Kumari, Neeraj; Nandi, Prantik; Naik, Sachindra; Patra, Dusmanta (Cornell University Library, 2020-08)
    We present the results obtained from a detailed X-ray timing and spectral analysis of the Seyfert 2 galaxy NGC 6300 by using observations from the Suzaku observatory, theChandra X-ray Observatory and the Nuclear Spectroscopic ...
  • Poddar, Tanmay Kumar; Mohanty, Subhendra (American Physical Society, 2020-10)
  • Bhardwaj, Akanksha; Konar, Partha; Mandal, Tanumoy; Sadhukhan, Soumya (American Physical Society, 2019-09)
    We explore the challenging but phenomenologically interesting hierarchical mass spectrum of the inert doublet model where relatively light dark matter along with much heavier scalar states can fully satisfy the constraints ...

    We present the results obtained from a detailed X-ray timing and spectral analysis of the Seyfert 2 galaxy NGC 6300 by using observations from the Suzaku observatory, theChandra X-ray Observatory and the Nuclear Spectroscopic ...
  • Singh, Balbeer; Bhatt, Jitesh R.; Mishra, Hiranmaya (American Physical Society, 2019-07)
    We study the effect of vorticity present in heavy ion collisions (HICs) on the temperature evolution of hot quark gluon plasma in the presence of spin-vorticity coupling. The initial global rotation entails a nontrivial ...
