Properties from relativistic coupled-cluster without truncation: hyperfine constants of , , and
B. K. Mani, D. Angom
We demonstrate an iterative scheme for coupled-cluster properties calculations without truncating the dressed properties operator. For validation, magnetic dipole hyperfine constan…
Spitzer IRAC imaging photometric study of the massive star forming region AFGL 437
L. K. Dewangan, B. G. Anandarao
We present {\it Spitzer} IRAC mid-infrared photometry on the massive star forming region AFGL 437 (IRAS 03035+5819). From the IRAC colour-colour diagram, we identify several new em…
Optical polarimetry and photometry of comet 17P/Holmes
U. C. Joshi, S. Ganesh, K. S. Baliyan
Comet 17P/Holmes was observed for linear polarisation using the optical polarimeter mounted on the 1.2m telescope atop Gurushikhar peak near Mt. Abu during the period November-Dece…
Type I seesaw mechanism for quasi degenerate neutrinos
Anjan S. Joshipura, Ketan M. Patel, Sudhir K. Vempati
We discuss symmetries and scenarios leading to quasi-degenerate neutrinos in type-I seesaw models. The existence of degeneracy in the present approach is not linked to any specific…
Neutrino Condensate as Origin of Dark Energy
Jitesh R. Bhatt, Bipin R. Desai, Ernest Ma +2
We propose a new solution to the origin of dark energy. We suggest that it was created dynamically from the condensate of a singlet neutrino at a late epoch of the early Universe t…
Ground State Geometry of Binary Condensates in Axisymmetric Traps
S. Gautam, D. Angom
We show that the ground state interface geometry of binary condensates in the phase separated regime undergoes a smooth transition from planar to ellipsoidal to cylindrical geometr…
