Self-trapped Exciton and Franck-Condon Spectra Predicted in LaMnO
Philip B. Allen, Vasili Perebeinos
Because the ground state has cooperative Jahn-Teller order, electronic excitations in LaMnO are predicted to self-trap by local rearrangement of the lattice. The optical spectr…

Toward a Theory of Orbiton Dispersion in LaMnO_3
Vasili Perebeinos, Philip B. Allen
At 750K, LaMnO_3 has a cooperative Jahn-Teller (JT) distortion, with Mn atoms in distorted oxygen octahedra. This lifts the degeneracy of the singly-occupied orbitals of the…
