Fermi pockets and quantum oscillations in specific heat of YBCO in the presence of disorder

Partha Goswami, Manju Rani, Avinashi Kapoor

We investigate a chiral d-density wave (CDDW) mean field model Hamiltonian in the momentum space suitable for the hole-doped cuprates, such as YBCO, in the pseudo-gap phase to obta…
