Quasinormal modes and Strong Cosmic Censorship

Vitor Cardoso, Joao L. Costa, Kyriakos Destounis +2

The fate of Cauchy horizons, such as those found inside charged black holes, is intrinsically connected to the decay of small perturbations exterior to the event horizon. As such,…

Functional renormalization group in stochastic inflation

Tomislav Prokopec, Gerasimos Rigopoulos

We apply the functional renormalization group to Starobinsky's stochastic equation describing the local dynamics of a light scalar field in de Sitter. After elaborating on the over…

Deducing Cosmological Observables from the S-matrix

S. P. Miao, T. Prokopec, R. P. Woodard

We study one loop quantum gravitational corrections to the long range force induced by the exchange of a massless scalar between two massive scalars. The various diagrams contribut…

Is Time Travel Too Strange to Be Possible? Determinism and Indeterminism on Closed Timelike Curves

Ruward A. Mulder, Dennis Dieks

Notoriously, the Einstein equations of general relativity have solutions in which closed timelike curves (CTCs) occur. On these curves time loops back onto itself, which has exotic…

Scalar field dark matter in hybrid approach

Tomislav Prokopec, Pavel Friedrich

We develop a hybrid formalism suitable for modeling scalar field dark matter, in which the phase-space distribution associated to the real scalar field is modeled by statistical eq…

Gravitational microlensing in Verlinde's emergent gravity

Lei-Hua Liu, Tomislav Prokopec

We propose gravitational microlensing as a way of testing the emergent gravity theory recently proposed by Eric Verlinde~\cite{Verlinde:2016toy}. We consider two limiting cases: th…
