Spin, Orbital, and Spin-Orbital Polarons in Transition Metal Oxides

I give a brief overview of a polaron formation in three distinct transition metal oxides: (i) spin polaron when a hole is added to the antiferromagnetic (AF) ordered plane in La2CuO4, (ii) orbital polaron when a hole is added to the alternating orbital (AO) ordered plane in LaMnO3, and (iii) spin-orbital polaron when a hole is added to the AF and AO ordered plane in LaVO3. Comparison of the dis...

Spin-carrying Spin Polarons in the T-j Model *

The report discusses the spinless-fermion (holon) representation of the t-J model and describes a new analytical representation in which fermion operators are directly related to the physical electron operators and have spin. A simple, leading-order, treatment of the magnetic dynamics allows to take into account the spin-liquid aspect of the ground state. The obtained effective model, in compar...
