Odd-parity perturbations of the wormhole-like geometries and quasi-normal modes in Einstein-\AE{}ther theory

Understand

The Einstein-$\AE$ther 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 shedding light on the attempts to construct quantum gravity.
• Since the first detection to the gravitational wave, the event GW150914, a brand new window has been opened to testing the theory of gravity with gravitational wave observations.
• At the same time, the study of gravitational waves itself also provides us a serendipity of accessing the nature of a theory.
