AbstractA reduced effective spin-orbital Hamiltonian in a symmetric spin-orbital system was derived by introducing the SU(4) Schwinger boson representation. After introducing a symmetric pairing VB order parameter, a mean field theory was developed, leading to a quantum disordered liquid state with a finite gap in the collective excitations in 1D and, on a 2D square lattice.
