Boson star superradiance (2024)
Journal Article

Recently, it has been realized that in some systems internal space rotation can induce energy amplification for scattered waves, similar to rotation in real space. In particularly, it has been shown that energy extraction is possible for a Q-ball, a... Read More about Boson star superradiance.

Ringdowns for black holes with scalar hair: The large mass case (2024)
Journal Article

Deviations from general relativity can alter the quasinormal mode (QNM) ringdown of perturbed black holes. It is known that a shift-symmetric (hence massless) scalar can only introduce black hole hair if it couples to the Gauss-Bonnet invariant, in w...

Quantum corrected Q-ball dynamics (2024)
Journal Article

The physics of individual Q-balls and interactions between multiple Q-balls are well-studied in classical numerical simulations. Interesting properties and phenomena have been discovered, involving stability, forces, collisions and swapping of charge... Read More about Quantum corrected Q-ball dynamics.
