  • Mondal, Tanmoy (Indian Institute of Technology Gandhinagar, 2016)
    In the history of elementary particle physics, the discovery of the Higgs boson at the Large Hadron Collider (LHC) in July 4, 202 is an important breakthrough which completes the Standard Model (SM) of particle physics. ...
  • Laskar, Fazlul I. (Indian Institute of Technology, Gandhinagar, 2014)
    The upper atmosphere of the Earth is influenced by incoming solar radiation (UV, EUV, and X-rays) and by secondary effects like waves from the lower atmosphere. The EUV radiation is absorbed above about 100 km altitude of ...
  • Roy, Arko (Indian Institute of Technology Gandhinagar, 2015)
    The stationary state solutions and dynamics of Bose-Einstein condensates (BECs) at T = 0 are well described by the Gross-Pitaevskii (GP) equation. BECs of dilute atomic gases have been experimentally achieved at ultracold ...
  • Aadhi, A. (Indian Institute of Technology Gandhinagar, 2015)
    Optical parametric oscillators (OPOs) have become standard source of coherent radiation inaccessible to ordinary lasers. Based on nonlinear optical effect, the OPOs convert a ffxed pump laser wavelength to a wide band of ...
  • Basak, Abhishek (Indian Institute of Technology, Gandhinagar, 2013)
    Inflationary scenario has been very successful in solving various problems associated with the standard Big Bang cosmology. But the nature of the field that drives accelerated expansion (inflaton) is still unknown to us. ...
  • Kushwaha, Upendra Kumar Singh (Indian Institute of Technology Gandhinagar, 2016)
    Solar eruptive phenomena correspond to various kind of transient activities occurring in the solar atmosphere in the form of flares, prominence eruptions and coronal mass ejections. They mostly originate from solar active ...
  • Apurv Chaitanya, N. (Indian Institute of Technology Gandhinagar, 2016-07)
    The general principles of Maxwell’s electromagnetic theory and quantum mechanics were well established much before the invention of lasers. However, after the first report of laser in 1960 and subsequent advancement in the ...
  • Patnaik, Akhil (Indian Institute of Technology Gandhinagar, 2017)
    One-Dimensional Fanno ow equations may be represented by the governing par- tial di erential equations for mass, momentum and energy conservation. The present study focuses on the numerical solution of one-dimensional ...
  • Chattopadhyay, Tanmoy (Indian Institute of Technology, Gandhinagar, 2015)
    Sensitive polarization measurements in X-ray may address a wealth of astrophysical phenomena, which so far remain beyond our understanding through available X-ray spectroscopic, imaging, and timing studies. Though scientific ...
  • Hati, Chandan (Indian Institute of Technology Gandhinagar, 2016)
    The Standard Model (SM) of particle physics has been highly successful in explaining most of the experimental measurements in elementary particle physics. It has survived decades of precision tests at highest available ...
  • Soni, Anurag (Indian Institute of Technology Gandhinagar, 2017)
    Spectral filters based on plasmonic and other high refractive index dielectric metasurfaces have significant advantages over dyes, pigments, and glass based filters due to their chemical stability, immunity to environmental ...
  • Jassal, Anjali Rao (Indian Institute of Technology Gandhinagar, 2015)
    Accretion around compact objects is the most efficient way of extracting energy from material in an accretion disk. Luminous accretion disks around black holes in mass transferring black hole binaries offer an opportunity ...
  • Midhun, M. (Indian Institute of Technology Gandhinagar, 2015)
    Stable oxygen isotope ratios (18O) of tree cellulose and speleothem carbonate are useful proxies for past monsoon rain in many tropical regions, as in such region a decrease in rain 18O accompanies an increase in rainfall ...
  • Nandy, Dillip Kumar (Indian Institute of Technology, Gandhinagar, 2015)
    In the standard model (SM) of particle physics it is a well-known fact that coupling constants of different fundamental interactions run with energy. The variations of these coupling constants under different local energy ...
  • Gaurav Kumar, Tomar (Indian Institute of Technology Gandhinagar, 2015)
    There are many observations in particle physics and cosmology, which seek physics beyond standard model for their explanation. Some of them are : The excess of positron over cosmic ray background observed by AMS-02 experiment, ...
  • Chandra, Naveen (Indian Institute of Technology Gandhinagar, 2016)
    The urban areas consist of more than half of the world’s population and contribute about 70% of the fossil fuel CO2 emissions (in 2010) as well as significant amount of anthropogenic emissions of CH4 into the atmosphere. ...
  • Kulkarni, Siddharth Vijay (Indian Institute of Technology Gandhinagar, 2017)
    Liquid Crystals (LCs) are soft materials with molecules possessing an orientational order similar to solids but with mobility similar to liquids. Addition of colloidal particles to LCs disturbs the molecular order and leads ...
  • Prabhakar, Shashi (Indian Institute of Technology, Gandhinagar, 2014)
    Optical vortices are singularities in the phase distribution of a light field. At the phase singularity, real and imaginary parts of the field vanish simultaneously and associated wavefront becomes helical. For an optical ...
