Relational path integral, effective actions and quantum frame covariance in gravity
Sergio E. Aguilar-Gutierrez, Renata Ferrero, Philipp A. Hoehn +1
We propose a relational bundle-geometric formulation of the gravitational path integral by invoking the new tool of quantum reference frames (QRFs), which in gravity are gauge-cova…
q-Askey Deformations of Double-Scaled SYK
Sergio E. Aguilar-Gutierrez, Trivko Kukolj, Josef Seitz
We construct families of deformations of the double-scaled SYK (DSSYK) model and investigate their bulk interpretation. We introduce microscopic deformations of the SYK model which…
Deforming the Double-Scaled SYK & Reaching the Stretched Horizon From Finite Cutoff Holography
Sergio E. Aguilar-Gutierrez
We study the properties of the double-scaled SYK (DSSYK) model under chord Hamiltonian deformations based on finite cutoff holography for general dilaton gravity theories with Diri…
Cosmological Entanglement Entropy from the von Neumann Algebra of Double-Scaled SYK & Its Connection with Krylov Complexity
Sergio E. Aguilar-Gutierrez
We investigate entanglement entropy between the pair of type II algebras of the double-scaled SYK (DSSYK) model given a chord state, its holographic interpretation as generaliz…
Probing the Chaos to Integrability Transition in Double-Scaled SYK
Sergio E. Aguilar-Gutierrez, Rathindra Nath Das, Johanna Erdmenger +1
We investigate how a thermodynamical first-order phase transition affects the dynamical chaotic behaviour of a given model. To this effect, we analyze the model of Berkooz, Brukner…
Geometry of Chord Intertwiner, Multiple Shocks and Switchback in Double-Scaled SYK
Sergio E. Aguilar-Gutierrez, Jiuci Xu
We revisit the bulk Hilbert space interpretation of chords in the double-scaled SYK (DSSYK) model and introduce a notion of intertwiner that constructs bulk states from states with…
