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…

Chiral d density wave ordered pseudo gap phase of Bi $_{2}$ Sr $_{2}$ CaCu $_{2}$ O $_{8 + δ}$ bilayer. Spin texture and Dzyaloshinskii Moriya interaction

Kakoli Bera, Udai Prakash Tyagi, Partha Goswami

We model Bi $_{2}$ Sr $_{2}$ CaCu $_{2}$ O $_{8 + δ}$ (Bi2212) bilayer system by an inversion symmetry broken and time reversal non invariant Bloch Hamiltonian H. The pseudo-gap phase of the bila…
