Abstract: We make use of the S= 1 pseudospin formalism to describe the charge degree of freedom in a model high-Tc cuprate with the on-site Hilbert space reduced to the three effective valence centers, nominally Cu1+,2+,3+. Starting with a parent cuprate as an analog of the quantum paramagnet ground state and using the Schwinger boson technique, we found the pseudospin spectrum and conditions for the pseudomagnon condensation with phase transition to a superconducting state. © 2019, Springer Science+Business Media, LLC, part of Springer Nature.
