Black Hole Memory Burden and its Signatures in Gravitational Waves from Mergers
Gia Dvali, Michael Zantedeschi, Sebastian Zell
Swift memory burden (MB) implies that the information stored in a black hole (BH) can modify its classical dynamics when the BH is perturbed. This influences the gravitational wave…
Removing the Cosmological Bound on the Axion Scale via Confinement During Inflation
Gia Dvali, Sophia Fitz, Lucy Komisel
We implement the scenario of early relaxation of the axion via a high scale confinement within grand unified theory and study an epoch of strong QCD in inflationary cosmolo…
Cosmological Implications of the Slingshot Effect: Gravitational Waves, Primordial Black Holes and Dark Matter
Maximilian Bachmaier, Gia Dvali, Juan Sebastián Valbuena-Bermúdez +1
In this paper, we explore the implications of the so-called slingshot effect. It represents a rather general phenomenon occurring when a localized source, such as a monopole, quark…
The Role of Microstate Degeneracy in Phase Transitions: Gravitational Waves from Bubble Entanglement
Gia Dvali, Lucy Komisel
Vacuum bubbles, formed in first order phase transitions, have important implications for cosmology. In particular, they source gravitational waves. Usually, it is assumed that, onc…
The Strong- Problem and its Gauge Axion solution as Evidence for Fundamental Strings
Gia Dvali, Lucy Komisel, Otari Sakhelashvili +1
The topological susceptibility of the QCD vacuum provides an understanding of -vacua as vacua of a Chern-Simons gauge theory. In this way, it gives an immediate proof of the ph…
On Time-Evolution in Quantum Gravity
Lasha Berezhiani, Gia Dvali, Otari Sakhelashvili
We derive an explicit BRST-exact operator identity for the bulk Hamiltonian in quantum gravity, working within a BRST-invariant quantization of General Relativity, treated as a low…
