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…

Electron spin orientation dependence on momentum in pseudo gap phase of Bi2212
Udai Prakash Tyagi, Partha Goswami
The aim of the paper is to study the electron spin direction dependence on momentum due to the presence of Rashba spin-orbit coupling in the pseudo-gap phase of Bi2212 bilayer. The…
