HECAP Seminar by Pietro Pelliconi - Yukawa–SYK in Quantum Simulators: from Open-System Dynamics to Holographic Signatures
Hybrid
Leonardo Building - Lagrange Lecture Hall and via Zoom
Abstract
Current state-of-the art control over target Hamiltonians in optical platforms opens to the possibility of simulating quantum many-body systems in a programmable way. Within this landscape, systems with holographic duals are particularly appealing targets, as their rich phenomenology connects high-energy physics, condensed matter, and quantum dynamics.
In this talk, I will focus on the Yukawa-SYK model, a version of the celebrated SYK model comprising both bosons and fermions. I will first review its phenomenology, emphasizing its similarities to and differences from \mathcal{N}=1 SYK, and discuss prospects for realization in cold-atom platforms.
I will then focus on the intrinsic open-system dynamics of such platforms, where the bosons leak out of the simulator. While in general such open-system dynamics heats up the simulation away from the holographic regime, leaving an imprint on two-point functions and on scrambling, I will show that the strong coupling limit is hidden in the statistics of temporal correlations of the leaked bosons. In turn, this also quantifies the experimental cost of probing the thermal holographic regime, as the number of events required to access it grows exponentially with (inverse) temperature.
