  • Sarkar, Sudipta (2020-12)
    Prof. Roger Penrose was awarded one-half of the Nobel prize in physics 2020 "for the discovery that black hole formation is a robust prediction of the general theory of relativity." Penrose�s landmark work on singularity ...
  • Mandal, Ipsita; Sen, Aritra (Cornell University Library, 2020-12)
    We investigate the tunneling of the quasiparticles arising in multi-Weyl semimetals through a barrier consisting of both electrostatic and vector potentials, existing uniformly in a finite region along the transmission ...
  • Nemala, Siva Sankar; Ravulapalli, Sujitha; Mallick, Sudhanshu; Bhargava, Parag; Bohm, Sivasambu; Bhushan, Mayank; Thakur, Anukul K.; Mohapatra, Debananda (MDP, 2020-11)
    Layers of titania are the critical components in sensitized photovoltaics. The transfer of electrons occurs from the dye molecule to the external circuit through a transparent conducting oxide, namely fluorine-doped tin ...
  • Chowdhuri, Abhishek; Bhattacharyya, Arpan (Cornell University Library, 2020-12)
    We explore the structure of shadow for a Kerr-de Sitter black hole with a non-magnetized, pressureless plasma surrounding it. Specific plasma distributions are considered to separate the Hamilton-Jacobi equation and find ...

  • Gowthama K. K.; Kurian, Manu; Chandra, Vinod (Cornell University Library, 2020-12)
    The electric charge transport in a weakly magnetized hot QCD medium has been investigated in the presence of an external inhomogeneous electric field. The current densities induced by the inhomogeneous electric field have ...

J.; Mason, Nigel J.; Sivaraman, Bhalamurugan (MDPI, 2020-11)
    The building blocks of life, amino acids, are believed to have been synthesized in the extreme conditions that prevail in space, starting from simple molecules containing hydrogen, carbon, oxygen and nitrogen. However, the ...
  • Kumar, Vipin; Srivastava, Mudit K; Banerjee, Dipankar P. K.; Joshi, Vishal (Oxford University Press, 2021-01)
    SU Lyn, a star that ostensibly appears to be an unremarkable late M type giant, has recently been proposed to be a symbiotic star largely based on its hard X-ray properties. The star does not display, in low-resolution ...

    A facile method has been developed to fabricate nano-encapsulated paraffin wax within silica shell (SNsPCM) by in-situ hydrolysis and polycondensation of silica precursor. SNsPCM composite was studied using field-effect ...
  • Jana, Arghajit; Chatterjee, Arka; Kumari, Neeraj; Nandi, Prantik; Naik, Sachindra; Patra, Dusmanta (Royal Astronomical Society, 2020-12)
    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 ...
  • Mazumdar, Arindam; Mohanty, Subhendra; Parashari, Priyank (Cornell University Library, 2020-11)
    Self interaction in the active neutrinos is studied in the literature to alleviate the H0 tension. Similar self-interaction can also explain the observed dips in the flux of the neutrinos, coming from the distant astro-physical ...
  • Ghosh, Rajes; Sarkar, Sudipta (American Physical Society, 2020-11)
    The zeroth law of black hole mechanics is an assertion of constancy of the surface gravity on a stationary Killing horizon. The Hawking temperature of the black hole horizon is proportional to the surface gravity. Therefore, ...
  • Jaisawal, Gaurava K.; Naik, Sachindra; Ho, Wynn C. G.; Kumari, Neeraj; Epili, Prahlad; Vasilopoulos, Georgios (Royal Astronomical Society, 2020-09)
    We present the results obtained from the analysis of high-mass X-ray binary pulsar 4U 1909+07 using NuSTAR and Astrosat observations in July 2015 and 2017, respectively. X-ray pulsations at ≈604 s are clearly detected in ...
  • Anwar, Ali; Lal, Nijil; Prabhakar, Shashi; Singh, R. P. (IOP Publishing, 2020-11)
    Spatial modes of light directly give the most easily accessible degree of freedom that span an infinite dimensional Hilbert space. The higher dimensional spatial mode entanglement realized using spontaneous parametric down ...
  • Ngairangbam, Vishal S.; Bhardwaj, Akanksha; Konar, Partha; Nayak, Aruna Kumar (Springer, 2020-11)
    Vector boson fusion proposed initially as an alternative channel for finding heavy Higgs has now established itself as a crucial search scheme to probe different properties of the Higgs boson or for new physics. We explore ...
  • 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 ...
  • Tripathi, Nidhi; Sahu, L. K.; Singh, Arvind; Yadav, Ravi; Patel, Anil; Patel, Kashyap; Meenu, P. (American Geophysical Union, 2020-11)
    The Arabian Sea is one of the most biologically productive ocean regimes and hence possesses a perennially intense oxygen minimum zone. High productive oceans can potentially modify the production and sea?to?air exchange ...
  • Coleppa, Baradhwaj; Sarkar, Agnivo (Cornell University Library, 2020-11)
    We discuss the structure of a model with an extended gauge symmetry group SU(2)�SU(2)�U(1) with a correspondingly rich Electroweak Symmetry Breaking structure. In spite of the additional scalar degrees of freedom in the ...
