Correlation patterns from massive phonons in 1+1 dimensional acoustic black holes: A toy model
arXiv:1809.03569 · doi:10.1103/PhysRevD.98.124011
Abstract
Transverse excitations in analogue black holes induce a mass like term in the longitudinal mode equation. With a simple toy model we show that correlation functions display a rather rich structure characterized by groups of parallel peaks. For the most part the structure is completely different from that found in the massless case.
