Multifield Cosmology and the Dark Universe
Lilia Anguelova
Multifield models, arising from multiple scalars interacting with gravity, provide a rich theoretical framework for addressing fundamental problems in modern cosmology. A key role…
Black hole thermodynamics at 4 derivatives, natural variables and BPS limits
Kiril Hristov, Peng-Ju Hu, Yi Pang
We study Einstein-Maxwell theory in spacetime dimensions including all Lorentz-invariant parity-even four-derivative couplings. Building on the results of arXiv:2312.116…
On the Consistency of Rapid-Turn Inflation
Lilia Anguelova
Recent studies, in the context of consistency conditions for rapid-turn and third order slow-roll inflation in two-field models, raised the question whether this regime can be sust…
Consistency Condition for Slow-roll and Rapid-turn Inflation
Lilia Anguelova, Calin Iuliu Lazaroiu
We summarize our work on a consistency condition for inflation in two-field cosmological models, in the regime of rapid turn and third-order slow roll. To ensure a sustained inflat…
Dynamics of Inspiraling Dark Energy
Lilia Anguelova, John Dumancic, Richard Gass +1
We investigate the dynamics of a multifield dark energy model, which arises from certain rapid-turning and inspiraling trajectories in field space. We find the speed of sound …
Explicit black hole thermodynamics in natural variables
Kiril Hristov
We consider the general thermal asymptotically flat Kerr-Newman black holes in 4d Einstein-Maxwell theory. Even though their thermodynamics has been understood for decades, the Gib…
