摘要：

We investigate the spectral functions and orbital correlation functions relative to the position of an e,. hole moving in the ferromagnetic plane of orbitally ordered LaMnO3. Polarization of orbitals around the hole leads to a very narrow quasiparticle band and to a confinement of the hole in an orbital polaron with the shape strongly depending on the type of the orbital order.
