On strong f-electron localization effect in topological kondo insulator
U. P. Tyagi, Kakoli Bera, Partha Goswami
We study strong f-electron localization effect on surface state of a generic topological Kondo insulator (TKI) system by performing a mean-field theoretic (MFT) calculation within…
The peculiar abundances of HE 1005-1439. A carbon-enhanced extremely metal-poor star contaminated with products of both s-and i-process nucleosynthesis
Partha Pratim Goswami, Aruna Goswami
We performed a detailed, high-resolution spectroscopic analysis of HE 1005-1439 based on SUBARU/HDS spectra with an R ~ 50000. Abundances of ten light elements from C through Ni an…
Chiral d density wave ordered pseudo gap phase of BiSrCaCuO bilayer. Spin texture and Dzyaloshinskii Moriya interaction
Kakoli Bera, Udai Prakash Tyagi, Partha Goswami
We model BiSrCaCuO (Bi2212) bilayer system by an inversion symmetry broken and time reversal non invariant Bloch Hamiltonian H. The pseudo-gap phase of the bila…
Spectroscopic study of CEMP-(s & r/s) stars- Revisiting classification criteria and formation scenarios, highlighting i-process nucleosynthesis
Partha Pratim Goswami, Rajeev Singh Rathour, Aruna Goswami
We have derived the stellar atmospheric parameters, the effective temperature T, the microturbulent velocity , the surface gravity log g, and the metallicity [Fe/H] for…
