TY - JOUR ID - 49440 AU - Churilova, Maria - Konoplya, Roman - Zhidenko, A. PY - 2020 TI - Arbitrarily long-lived quasinormal modes in a wormhole background JF - Physics Letters B VL - 802 IS - March SP - "135207-1"-"135207-5" EP - "135207-1"-"135207-5" SN - 03702693 KW - HOLE NORMAL-MODES KW - BLACK-HOLES UR - https://www.sciencedirect.com/science/article/pii/S0370269320300113 N2 - Arbitrarily long lived modes, called quasi-resonances, are known to exist in the spectrum of massive fields for a number of black-hole backgrounds at some discrete values of mass of the field. Here we show that these modes also exist in the background of wormholes, unless a wormhole has a constant red-shift function, that is, tideless in the radial direction. The evidence of quasi-resonances is supported by calculations in the frequency and time domains, which are in a good concordance. At large masses of the field, time-domain profiles of the absolute value of the wave function have peculiar behavior: the long-lived modes dominate in the signal after a long period of power-law tails.
