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…
Evolution With(out) Time: Relational Holography & BPS Complexity Growth in Double-Scaled SYK
Sergio E. Aguilar-Gutierrez
How do we describe non-trivial bulk measurements relative to an observer (i.e. relationally) when both the observer and the system it probes may/may not evolve in time? How can we…
Symmetry Sectors in Chord Space and Relational Holography in the DSSYK
Sergio E. Aguilar-Gutierrez
In holography, gauging symmetries of the boundary theory leads to important modifications in the bulk. In this work, we study constraints to gauge symmetry sectors in the chord Hil…
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…
Quasinormal modes and complexity in saddle-dominated SU(N) spin systems
Sergio E. Aguilar-Gutierrez, Yichao Fu, Kuntal Pal +1
We study SU() spin systems that mimic the behavior of particles in -dimensional de Sitter space for . Their Hamiltonians describe a dynamical system with hyperbolic fi…
Krylov operator complexity in holographic CFTs: Smeared boundary reconstruction and the dual proper radial momentum
Sergio E. Aguilar-Gutierrez, Hugo A. Camargo, Viktor Jahnke +2
Motivated by bulk reconstruction of smeared boundary operators, we study the Krylov complexity of local and non-local primary CFT operators from the local bulk-to-bulk propagat…
