Chiral d density wave ordered pseudo gap phase of Bi${}_2$Sr${}_2$CaCu${}_2$O${}_{8+\delta }$ bilayer. Spin texture and Dzyaloshinskii Moriya interaction

Kakoli Bera, Udai Prakash Tyagi, Partha Goswami

We model Bi${}_2$Sr${}_2$CaCu${}_2$O${}_{8+\delta }$ (Bi2212) bilayer system by an inversion symmetry broken and time reversal non invariant Bloch Hamiltonian H. The pseudo-gap phase of the bila…
