Spin-orbital entanglement near quantum phase transitions
Spin-orbital entanglement in the ground state of a one-dimensional SU(2)⊗SU(2) spin-orbital model is analyzed using exact diagonalization of finite chains. For S = 1/2 spins and T = 1/2 pseudospins one finds that the quantum entanglement is similar at the SU(4) symmetry point and in the spin-orbital valence bond state. We also show that quantum transitions in spin-orbital models turn out to be ...
متن کاملSpin–Orbital Physics in Transition Metal Oxides
We present the main features of the spin-orbital superexchange which describes the magnetic and optical properties of Mott insulators with orbital degrees of freedom. In contrast to the SU(2) symmetry of spin superexchange, the orbital part of the superexchange obeys the lower cubic symmetry of the lattice and is intrinsically frustrated. This intrinsic frustration and spin-orbital entanglement...
متن کاملPhase diagram and symmetry breaking of an SU„4... spin-orbital chain in a generalized external field
The ground-state phases of a one-dimensional SU~4! spin-orbital Hamiltonian in a generalized external field are studied on the basis of the Bethe-ansatz solution. Introducing three Landé g factors for spin, orbital, and their products in the SU~4! Zeeman term, we systematically discuss various symmetry breakings. The magnetization versus external field is evaluated by solving the Bethe-ansatz e...
متن کاملNoncollinear magnetic order stabilized by entangled spin-orbital fluctuations.
Quantum phase transitions in the two-dimensional Kugel-Khomskii model on a square lattice are studied using the plaquette mean field theory and the entanglement renormalization Ansatz. When 3z(2)-r(2) orbitals are favored by the crystal field and Hund's exchange is finite, both methods give a noncollinear exotic magnetic order that consists of four sublattices with mutually orthogonal nearest-n...
متن کاملSpin-orbital gapped phase with least symmetry breaking in the one-dimensional symmetrically coupled spin-orbital model
To describe the spin-orbital energy gap formation in the one-dimensional symmetrically coupled spin-orbital model, we propose a simple mean field theory based on an SU(4) constraint fermion representation of spins and orbitals. A spin-orbital gapped phase is formed due to a marginally relevant spin-orbital valence bond pairing interaction. The energy gap of the spin and orbital excitations grow...
