Fledgling quantum spin Hall effect in pseudo gap phase of Bi2212
Udai Prakash Tyagi, Kakoli Bera, Partha Goswami
We study the emergence of the quantum spin Hall (QSH) states for the pseudo-gap (PG) phase of Bi2212 bilayer system, assumed to be D-density wave(DDW) ordered, starting with a stro…

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 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…
