Kaluza-Klein Spectroscopy from Neutron Oscillations into Hidden Dimensions
Gia Dvali, Manuel Ettengruber, Anja Stuhlfauth
Neutrons and neutrinos are natural probes for new physics. Since they carry no conserved gauge quantum numbers, both can easily mix with the fermions from hidden sectors. A particu…
Vortex Effects in Merging Black Holes and Saturons
Gia Dvali, Oleg Kaikov, Florian Kuhnel +2
Vorticity has recently been suggested to be a property of highly-spinning black holes. The connection between vorticity and limiting spin represents a universal feature shared by o…
Confinement Slingshot and Gravitational Waves
Maximilian Bachmaier, Gia Dvali, Juan Sebastián Valbuena-Bermúdez +1
In this paper, we introduce and numerically simulate a quantum field theoretic phenomenon called the gauge ``slingshot" effect and study its production of gravitational waves. The…
Radiation Emission during the Erasure of Magnetic Monopoles
Maximilian Bachmaier, Gia Dvali, Juan Sebastián Valbuena-Bermúdez
We study the interactions between 't Hooft-Polyakov magnetic monopoles and the domain walls formed by the same order parameter within an gauge theory. We observe that the c…
Neutrinoless double beta decay: neutrino mass versus new physics
Gia Dvali, Alessio Maiezza, Goran Senjanovic +1
Neutrinoless double beta decay is the textbook example of lepton number violation, often claimed to be a probe of neutrino Majorana mass. However, it could be triggered by new phys…
Black holes as tools for quantum computing by advanced extraterrestrial civilizations
Gia Dvali, Zaza N. Osmanov
We explain that black holes are the most efficient capacitors of quantum information. It is thereby expected that all sufficiently advanced civilizations ultimately employ black ho…
