DOI: 10.1007/jhep01(2022)087
Abstract: We investigate the possibility of using quasi-normal modes (QNMs) to probe the microscopic structure of two-dimensional (2D) anti-de Sitter (AdS 2 ) dilatonic black holes. We first extend previous results on the QNMs spectrum, found… read more here.

Abstract: Transmission through disordered samples can be controlled by illuminating a sample with waveforms corresponding to the eigenchannels of the transmission matrix (TM). But can the TM be exploited to selectively excite quasi-normal modes and so… read more here.

DOI: 10.1088/1475-7516/2023/05/059
Abstract: The Einstein-Æther theory has drawn a lot of attentions in recent years. As a representative case of gravitational theories that break the Lorentz symmetry, it plays an important role in testing the Lorentz-violating effects and… read more here.

DOI: 10.1103/physrevd.98.024017
Abstract: We show that not all quasinormal modes of a massless scalar field in the Schwarzschild metric are encoded in the corresponding characteristic equation expressed by means of a continued fraction. We provide an analytical formula… read more here.

Abstract: A Drazin invertible operator T ? B(H) is called skew D-quasi-normal operator if T* and TTD commute or equivalently TTD is normal. In this paper, firstly we give a list of conditions on an operator… read more here.
