Single bipolaronic Transition in Jahn-Teller Model
Reza Nourafkan, Massimo Capone, Nasser Nafari
We investigate the bipolaronic crossover and the pairing transition for a two-orbital model with Jahn-Teller coupling to a two-fold degenerate phonon mode. The evolution from weak…

Antiferromagnetism and the gap of a Mott insulator: Results from analytic continuation of the self-energy
Xin Wang, Emanuel Gull, Luca de' Medici +2
Direct analytic continuation of the self energy is used to determine the effect of antiferromagnetic ordering on the spectral function and optical conductivity of a Mott insulator.…
