  • Fundamental interactions in the early universe 
    Sivaram, C (Springer, 1994-05)
    A unified approach to fundamental interactions as explored earlier is further elaborated and its consequences for the early universe studied especially in connection with the energy dependence of the coupling constants.
  • Influence of correlation effects on the magnetic dipole hyperfine interaction in the low-lying states of Ca+ 
    Sahoo, B. K; Chaudhuri, R. K; Das, B. P; Majumder, S; Merlitz, H; Mahapatra, U. S; Mukherjee, D (Institute of Physics Publishing Ltd., 2003-05-28)
    The relativistic coupled cluster theory is employed to calculate the hyperfine structure of the 2S 1/2, 2P 1/2, 2P 3/2, 2D 3/2 and 2D 5/2 states of singly ionized calcium. The importance of correlation effects is highlighted. ...
  • Mond, dark matter and the cosmological constant 
    Sivaram, C (Springer, 1994-09)
    A possible connection between MOND (Modification of Newtonian Dynamics) proposed as an alternative hypothesis to dark matter in galaxies and clusters and a residual cosmological constant term dominating cosmological dynamics ...
  • Non-zero rest mass neutrinos and the cosmological constant 
    Sivaram, C (Kluwer Academic Publisher, 1985-11)
    Recently it was pointed out that a non-zero cosmological constant can play a role in the formation of neutrino halos only in the case of neutrinos of very low rest mass (mν ≤ 0.1 eV). However, phase-space considerations ...

  • Variations of the coupling constants of fundamental interactions in Dirac's cosmology 
    Sivaram, C (Springer, 1984-03)
    It is pointed out that several interesting coincidences and relationships connecting the parameters of cosmology and elementary particle physics suggest that the coupling constants of the weak, strong and electromagnetic ...
