Unimodular time in JT gravity: a holographic clock
Altay Etkin, Farbod-Sayyed Rassouli
How is a ''bulk clock'' encoded holographically? We address this in Jackiw-Teitelboim (JT) gravity, where a natural physical clock emerges by promoting the vacuum energy to a dynam…
Mind the crosscap: -scaling in non-orientable gravity and time-reversal-invariant systems
Gabriele Di Ubaldo, Altay Etkin, Felix M. Haehl +1
Spectral statistics of quantum chaotic systems are governed by random matrix universality. In many cases of interest, time-reversal symmetry selects the Gaussian Orthogonal Ensembl…
Unimodular JT gravity and de Sitter quantum cosmology
Bruno Alexandre, Altay Etkin, Farbod-Sayyed Rassouli
In this work, we show that a gauge-theoretic description of Jackiw-Teitelboim (JT) gravity naturally yields a Henneaux-Teitelboim (HT) unimodular gravity via a central extension of…
Vortices, topology and time
Altay Etkin, João Magueijo, Farbod-Sayyed Rassouli
We relate physical time with the topology of magnetic field vortices. We base ourselves on a formulation of unimodular gravity where the cosmological constant appears as the ca…
