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…

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…
