PT Journal AU Dudley, RA Anderson, PR Balbinot, R Fabbri, A TI Correlation patterns from massive phonons in 1+1 dimensional acoustic black holes: A toy model SO Physical Review D JI Phys. Rev. D PY 2018 BP 124011 EP 18pp VL 98 IS 12 DI 10.1103/PhysRevD.98.124011 LA English AB Transverse excitations in analogue black holes induce a masslike 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 approximately parallel peaks. For the most part the structure is completely different from that found in the massless case. ER
