Exceptional points for associated Legendre functions of the second kind

Autor: Liu, Tianye, Norman, Daniel A., Mannheim, Philip D.

We consider the complex $\nu$ plane structure of the associated Legendre function of the second kind $Q^{-1/2-K}_{\nu}(\cosh\rho)$. We find that for any noninteger value for $K$ $Q^{-1/2-K}_{\nu}(\cosh\rho)$ has an infinite number of poles in the com

Exact solution to perturbative conformal cosmology from recombination until the current era

Autor: Amarasinghe, Asanka, Liu, Tianye, Norman, Daniel A., Mannheim, Philip D.

Publikováno v: Phys. Rev. D 103, 104022 (2021)

In a previous paper (P. D. Mannheim, Phys. Rev. D 102, 123535 (2020)) we studied cosmological perturbation theory in the cosmology associated with the fourth-order derivative conformal gravity theory, and provided an exact solution to the theory in t

Dielectric perturbations: anomalous resonance frequency shifts in optical resonators

Autor: Azeem, Farhan, Trainor, Luke S., Devane, Patrick A., Norman, Daniel S., Rueda, Alfredo, Lambert, Nicholas J., Kumari, Madhuri, Foreman, Matthew R., Schwefel, Harald G. L.

Small perturbations in the dielectric environment around a high quality whispering gallery mode resonator usually lead to a frequency shift of the resonator modes directly proportional to the polarizability of the perturbation. Here, we report experi
