  • Vishwakarma, Ashok K.; Ghalsasi, Pallavi; Ghalsasi, Prasanna S. (Wiley, 2011-08)
    The existence of various solid phases of organic ammonium halides, due to the presence of hydrogen bonding, has long been established but is limited to alkyl ammonium halides. On the other hand, the presence of such phase ...
  • Lorch, Christopher; Banerjee, Rupak; Dieterle, Johannes; Hinderhofer, Alexander; Gerlach, Alexander; Drnec, J.; Schreiber, Frank (American Chemical Society (ACS), 2015-09)
    Small-molecule organic photovoltaic cells often employ a planar heterojunction (PHJ) geometry where the electron donor and acceptor materials are stacked one on top of the other. The thin-film growth scenario of such PHJs ...
  • Chandra, Naveen; Lal, Shyam; Venkataramani, S.; Patra, Prabir K.; Sheel, Varun (Copernicus Publications, 2016-05)
    About 70 % of the anthropogenic carbon dioxide (CO2) is emitted from the megacities and urban areas of the world. In order to draw effective emission mitigation policies for combating future climate change as well as ...
  • Lambiase, Gaetano; Mohanty, Subhendra; Narang, Ashish; Parashari, Priyank (Springer, 2019-02)
    It has been pointed out that there exists a tension in σ8−Ωm measurement between CMB and LSS observation. In this paper we show that σ8−Ωm observations can be used to test the dark energy theories. We study two models, (1) ...
  • Sengupta, Anand (American Physical Society, 2016-06)
    The LIGO detection of GW150914 provides an unprecedented opportunity to study the two-body motion of a compact-object binary in the large-velocity, highly nonlinear regime, and to witness the final merger of the binary and ...
  • Sengupta, Anand (American Physical Society, 2019-07)
    The recent discovery by Advanced LIGO and Advanced Virgo of a gravitational wave signal from a binary neutron star inspiral has enabled tests of general relativity (GR) with this new type of source. This source, for the ...
  • Bhalla, Pankaj; Kumar, Pradeep; Das, Nabyendu; Singh, Navinder (American Physical Society, 2016-09)
    The Mori's projection method, known as the memory function method, is an important theoretical formalism to study various transport coefficients. In the present work, we calculate the dynamical thermal conductivity in the ...
  • Mitra, Sukanya; Chandra, Vinod (American Physical Society, 2016-08)
    The response of electromagnetic (EM) fields that are produced in noncentral heavy-ion collisions to electromagnetically charged quark gluon plasma can be understood in terms of charge transport and charge diffusion in the ...
  • Roy, Arko; Angom, D. (American Physical Society, 2015-07)
    We examine the role of thermal fluctuations in binary condensate mixtures of dilute atomic gases. In particular, we use the Hartree-Fock-Bogoliubov theory with the Popov approximation to probe the impact of noncondensate ...
  • Mitra, Sukanya (Springer Verlag, 2018-01)
    The thermodynamics and covariant kinetic theory are elaborately investigated in a non-extensive environment considering the non-extensive generalization of Bose–Einstein (BE) and Fermi–Dirac (FD) statistics. Starting with ...
  • Mohd, Arif; Sarkar, Sudipta (American Physical Society, 2013-07)
    We propose an expression for the entropy density associated with the local causal horizons in any diffeomorphism-invariant theory of gravity. If the black-hole entropy of the theory satisfies the physical process version ...
  • Venkataramani, Kumar; Ganesh, Shashikiran; Rai, Archita; Hus�rik, Marek; Baliyan, K. S.; Joshi, U.C (Institute of Physics, 2019-06)
    The asteroid 2014 JO25, considered to be potentially hazardous by the Minor Planet Center, was spectroscopically followed during its close-Earth encounter on 2017 April 19 and 20. The spectra of the asteroid were taken ...
  • Ali, Ahmed Farag; Majumder, Barun (IOP Science, 2014-10)
    The Friedmann–Robertson–Walker (FRW) universe and Bianchi I, II universes are investigated in the framework of the generalized uncertainty principle (GUP) with a linear and a quadratic term in Planck length and momentum, ...
  • Hati, Chandan; Patra, Sudhanwa; Reig, Mario; Valle, Jose W.F.; Vaquera-Araujo, C.A. (American Physical Society, 2017-07)
    We consider the possibility of gauge coupling unification within the simplest realizations of the SU(3)c×SU(3)L×SU(3)R×U(1)X gauge theory. We present a first exploration of the renormalization group equations governing the ...
  • Abhishek, Aman; Mishra, Hiranmaya; Ghosh, Sabyasachi (American Physical Society, 2018-01)
    We compute the transport coefficients, namely, the coefficients of shear and bulk viscosities, as well as thermal conductivity for hot and dense matter. The calculations are performed within the Polyakov quark meson model. ...
  • Mitra, Sukanya; Chandra, Vinod (American Physical Society, 2017-11)
    The main focus of this article is to obtain various transport coefficients for a hot QCD medium that is likely to be produced while colliding two heavy nuclei ultra-relativistically. The technical approach adopted here is ...
  • Kurian, Manu; Mitra, Sukanya; Ghosh, Snigdha; Chandra, Vinod (Springer, 2019-02)
    In this article, shear viscosity, bulk viscosity, and thermal conductivity of a QCD medium have been studied in the presence of a strong magnetic field. To model the quark–gluon plasma, an extended quasi-particle description ...
  • Ghosh, Sabyasachi; Serna, Fernando E.; Abhishek, Aman; Krein, Gastão; Mishra, Hiranmaya (American Physical Society, 2019-01)
    We have calculated quark and antiquark relaxation time by considering different possible elastic and inelastic scatterings in the medium. Comparative roles of these elastic and inelastic scatterings on different transport ...
  • Sharma, Varun; Chaitanya Kumar, S.; Aadhi, A.; Ye, H.; Samanta, G. K.; Ebrahim-Zadeh, M. (Springer Nature Publishing, 2019-07)
    Vector-vortex beams, having both phase and polarization singularities, are of great interest for a variety of applications. Generally, such beams are produced through systematic control of phase and polarization of the ...
  • Apurv Chaitanya, N.; Aadhi, A.; Singh, Ravindra P.; Samanta, Goutam Kumar (Optical Society of America, 2014-08)
    We report on experimental realization of optimum focusing condition for type-I second-harmonic generation (SHG) of high-power, ultrafast laser in “thick” nonlinear crystal. Using single-pass, frequency doubling of a 5 W ...
