  • Mishra, Shubhankar; Roy, Amritendu; Sahoo, Aditi; Satpati, Biswarup; Roychowdhury, Anirban; Mohanty, P. K.; Ghosh, Chandan Kumar; Bhattacharya, Dipten (American Physical Society, 2022-06)
    We report observation of surface-defect-induced room-temperature multiferroicity—surface ferromagnetism (MS at 50 kOe ≈0.005 emu/g), ferroelectricity (PR ≈ 2 nC/cm2), and significantly large magnetoelectric coupling (decrease ...
  • Chakraborty, Arup; Sreekantham, Rithvik Kumar; Sahoo, B. K. (American Physical Society, 2022-06)
    We present precise values of electric polarizabilities for the ground state of Zn due to second-order dipole and quadrupole interactions, and due to third-order dipole-quadrupole interactions. These quantities are evaluated ...
  • Saha, Madhumita; Venkatesh, B. Prasanna; Agarwalla, Bijay Kumar (American Physical Society, 2022-06)
    Quasiperiodic lattice systems offer diverse transport properties. In this paper, we investigate environment-induced effects on the transport properties for quasiperiodic systems, namely the one-dimensional Aubry-Andre-Harper ...
  • Ghosh, Anupam; Konar, Partha; Seth, Satyajit (American Physical Society, 2022-06)
    The inert Higgs-doublet model provides a simple framework to accommodate a viable Higgs portalscalar dark matter candidate, together with other heavier scalars of mass 100 GeV or more. We study the effect of next-to-leading ...
  • Roy, Soumen; Sengupta, Anand S. et al. (IOP Publishing, 2022-06)
    Isolated neutron stars that are asymmetric with respect to their spin axis are possible sources of detectable continuous gravitational waves. This paper presents a fully coherent search for such signals from eighteen pulsars ...
  • Mishra, Sanjay K.; Sana, Trinesh (Oxford University Press, 2022-06)
    A scheme based on natural quantum electric field tunneling to mitigate the substantial charge deposition due to triboelectric (frictional) charging from the drill setup, operating in the shadowed region of the Moon, is ...
  • Bansal, Anshika; Mahajan, Namit (Springer, 2022-06)
    Proton decay is a baryon number violating process, and hence is forbidden in the Standard Model (SM) of particle physics. Baryon number violation is expected to be an important criteria to explain the matter-anti-matter ...
  • Konar, Partha; Ngairangbam, Vishal S. (American Physical Society, 2022-06)
    Vector boson fusion established itself as a highly reliable channel to probe the Higgs boson and an avenue to uncover new physics at the Large Hadron Collider. This channel provides the most stringent bound on Higgs's ...
  • Lal, Nijil; Mishra, Sarika; Singh, R. P. (American Institute of Physics, 2022-06)
    Quantum mechanics allows identical particles to lose their individuality completely and become truly indistinguishable. This property of indistinguishability gives rise to exclusive quantum phenomena such as two particle ...
  • Yogesh; Chakrabarty, Dibyendu K.; Srivastava, Neeraj (Oxford University Press, 2022-06)
    Despite helium abundance (AHe = nH/nHe) being ∼8 per cent at the solar photospheric/chromospheric heights, AHe can be found to exceed 8 per cent in interplanetary coronal mass ejections (ICMEs) on many occasions. Although ...
  • Roy, Soumen; Sengupta, Anand S. et al. (Oxford University Press, 2022-06)
    We report the results of the first joint observation of the KAGRA detector with GEO 600. KAGRA is a cryogenic and underground gravitational-wave detector consisting of a laser interferometer with 3 km arms, located in ...
  • Mitra, Shirsendu; Basak, Mitali (Elsevier, 2022-06)
    Substantial advancements have been observed over the years in the research and development of Localized Surface Plasmon Resonance (LSPR). A variety of current and future applications involving anisotropic plasmonic ...
  • Singh, Naman Deep; Singh, Sunil Kumar (Elsevier, 2022-06)
    Dissolved aluminium (dAl) distribution has been studied over the full vertical water column profiles along the GEOTRACES-India (GI) transect, GI-05, in the Arabian Sea (AS) and the Western Equatorial Indian Ocean (W-Eq.IO) ...
  • Tripathi, Nidhi; Sahu, L. K.; Wang, Liwei; Vats, Pawan; Soni, Meghna; Kumar, Purushottam; Satish, R., V; Bhattu, Deepika; Sahu, Ravi; Patel, Kashyap; Rai, Pragati; Kumar, Varun; Rastogi, Neeraj; Ojha, Narendra; Tiwari, Shashi; Ganguly, Dilip; Slowik, Jay; Prevot, Andre S. H.; Tripathi, Sachchida N. (American Geophysical Union, 2022-06)
    Simultaneous measurements of volatile organic compounds (VOCs) using two PTR-TOF-MS instruments were conducted at urban and suburban sites of New Delhi during the winter of 2018. The time series of VOC mixing ratios show ...
  • Jana, Arghajit; Ricci, Claudio; Naik, Sachindra; Tanimoto, Atsushi; Kumari, Neeraj; Chang, Hsiang-Kuang; Nandi, Prantik; Chatterjee, Arka; Safi-Harb, Samar (Royal Astronomical Society, 2022-06)
    We present a detailed study of the highly obscured active galaxy NGC 4507, performed using four Nuclear Spectroscopic Telescope Array (NuSTAR) observations carried out between May and August in 2015 (?130 ks in total). ...
  • Coleppa, Baradhwaj; Sarkar, Agnivo (SpringerOpen, 2022-06)
    We discuss the structure of a model with anextended gauge symmetry groupSU(2)×SU(2)×U(1)with a correspondingly rich Electroweak Symmetry Break-ing structure. In spite of the additional scalar degrees of free-dom ...
