Vibrational effects on polarizability: insights from normal mode analysis by Tiago de Sousa Araújo Cassiano, Víctor de Souza Assumção Bonfim, Pedro Henrique de Oliveira Neto, Demétrio Antônio da Silva Filho

“…It is revealed that vibrational effects can introduce uncertainties of up to 6% in sensing devices and 50% in optical devices due to nuclear oscillations. Furthermore, normal mode analysis highlights specific vibrational modes that enhance molecular polarizability.…”

Quasi-normal modes of slowly-rotating Johannsen black holes by Yuhao Guo, Swarnim Shashank, Cosimo Bambi

“…We find that the deformation parameter $$\alpha _{13}$$ α 13 has a stronger impact on the quasi-normal modes than the other leading order deformation parameters ( $$\alpha _{22}$$ α 22 , $$\alpha _{52}$$ α 52 , and $$\epsilon _{3}$$ ϵ 3 ). …”

On destabilising quasi-normal modes with a radially concentrated perturbation by Valentin Boyanov

“…In this work we explore some aspects of the spectral instability of back hole quasi-normal modes, using a specific model as an example. The model is that of a small bump perturbation to the effective potential of linear axial gravitational waves on a Schwarzschild background, and our focus is on three different aspects of the instability: identifying and distinguishing between the two different types of instabilities studied previously in the literature, quantifying the size of the perturbations applied to the system and testing the validity of the pseudospectral numerical method in providing a convergent result for this measure, and finally, relating the size and other features of the perturbation to the degree of destabilisation of the spectrum.…”
