  • Midhun, M.; Ramesh, R. (Springer, 2016-03)
    Stable oxygen isotope ratios (δ18O) of tree cellulose and speleothem carbonate are useful proxies for past monsoon rain in many tropical regions, as a decrease in rain δ18O is observed with increase in rainfall on a monthly ...
  • Mallika, Chinmay; Chandra, Naveen; Venkataramani, S.; Lal, Shyam (Elsevier, 2016-05)
    Atmospheric carbonyl sulfide (COS) is a major precursor for sulfate aerosols that play a critical role in climate regulation. Recent studies have highlighted the importance of COS measurements as a reliable means to constrain ...
  • Laskar, Fazlul I.; Pallamraju, Duggirala; Veenadhari, Bhaskara (Terra Scientific Publishing Company, 2014-08)
    Comprehensive behavior of the low-latitude upper atmosphere during sudden stratospheric warming (SSW) events at varying levels of solar activity has been investigated. The equatorial electrojet (EEJ) strength and the total ...
  • Prabhakar, Shashi; Salla, Gangi Reddy; Aadhi, A.; Perumangatt, Chithrabhanu; Samanta, Goutam Kumar; Singh, Ravindra P. (American Physical Society, 2015-08)
    We have considered optical beams with phase singularity and experimentally verified that these beams, although classical, have properties of two-mode entanglement in quantum states. We have observed the violation of Bell's ...
  • Ghosh, Snigdha; Samanta, Subhasis; Ghosh, Sabyasachi; Mishra, Hiranmaya (World Scientific Publishing, 2019-06)
    We have attempted to review on microscopic calculation of transport coefficients like shear and bulk viscosities in the framework of hadron resonance gas (HRG) model, where a special attention is explored on the effect of ...
  • Bhatt, Jitesh R.; Mishra, Arvind Kumar; Nayak, Alekha C. (American Physical Society, 2019-09)
  • Atreya, Abhishek; Bhatt, Jitesh R.; Mishra, Arvind (IOP Publishing, 2018-02)
    Self interacting dark matter (SIDM) provides us with a consistent solution to certain astrophysical observations in conflict with collision-less cold DM paradigm. In this work we estimate the shear viscosity (η) and bulk ...
  • Atreya, Abhishek; Bhatt, Jitesh R.; Mishra, Arvind (IOP Publishing, 2019-02)
    The viscosity of dark matter in cosmological models may cause an accelerated expansion and when this effect is sufficiently large, it can explain the dark energy. In this work, attributing the origin of viscosity to ...
  • Bhagwat, Ameeya A.; Vinas, X.; Wyss, R.; Schuck, P. (World Scientific Publishing, 2010-04)
    We propose to use the semi-classical Wigner-Kirkwood ħ expansion to calculate shell corrections for spherical and deformed nuclei. The expansion is carried out up to fourth order in ħ. A systematic study of Wigner-Kirkwood ...
  • Ghosh, Snigdha; Sarkar, Sourav; Mitra, Sukanya (American Physical Society, 2017-03)
    The self-energy of the Δ baryon is evaluated at a finite temperature and density using the real-time formalism of thermal field theory. The Dyson-Schwinger equation is used to get the exact thermal propagator followed ...
  • Mohanty, Subhendra; Anand, Sampurn; Chaubal, Prakrut; Mazumdar, Arindam; Parashari, Priyank (Springer, 2018-08)
    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 ...
