Single hole motion in LaMnO3
We study single hole motion in LaMnO3 using the classical approximation for Jahn-Teller lattice distortions, a modified Lang-Firsov approximation for dynamical breathing-mode phonons, and the self-consistent Born approximation (verified by exact diagonalization) for hole-orbital-excitation scatterin...

| description | We study single hole motion in LaMnO3 using the classical approximation for Jahn-Teller lattice distortions, a modified Lang-Firsov approximation for dynamical breathing-mode phonons, and the self-consistent Born approximation (verified by exact diagonalization) for hole-orbital-excitation scattering. We show that in the realistic parameter space for LaMnO3, quantum effects of electron-phonon interaction are small. The quasiparticle bandwidth is about 2.2J in the purely orbital t-J model. It is strikingly broadened to be of order t by strong static Jahn-Teller lattice distortions even when the polaronic band narrowing is taken into account. |
