Fig. 4: EP propagation ensuing excitation at resonant wavevector.
From: Quantum dynamics simulation of exciton-polariton transport

a Real-space resolved total polaritonic density ∣ψpol(x, t)∣2 for resonant-wavevector excitation to the LPB. b Real-space resolved total polaritonic density ∣ψpol(x, t)∣2 and photonic contribution ∣ψphot(x, t)∣2 for resonant-wavevector excitation to the UPB. Red lines indicate the expectation value of the position operator. c MSDs extracted from polaritonic real-space resolved densities in (a) and (b). d Momentum-resolved cavity mode populations corresponding to EP propagations at κ = 80 meV in (a) and (b). Yellow lines indicate the expectation value of the cavity-mode momentum operator.
