README: MoirĂ©-Induced Optical Nonlinearities: Single and Multiphoton Resonances
Folder containing the data for the manuscript MoirĂ©-Induced Optical Nonlinearities: Single and Multiphoton Resonances by A. Camacho-Guardian and N. R. Cooper.
METHODS
As described in following, the data was obtained either by exact diagonalization of the Lindblad operator or the solution of the extended Gross-Pitaevskii as defined in the main text.
FIGURES
Figure 2
a) Phase diagram obtained by exact diagonalization of the Lindblad operator. Regimes of high and low density are separated by a bistability that can be accessed via hysteresis.

(b) and (c) Exciton number obtained by exact diagonalization of the Lindblad operator. Fig. 2(a) corresponds to the low branch where the pump strength is varied from below. Fig. 2(b) illustrates the hysteresis as the pump strength is tuned from an initial large value.
