Hayden--Preskill recovery at finite temperature on a quantum processor: dynamics and initial state from the SYK model
Jeongho Bang, Moongul Byun, Kyoungho Cho +2
In the original Hayden--Preskill recovery, the post-injection scrambler and initial state are {\it not related}. We extend this setup in two ways: by using a SWAP gate so that the…
Quantum simulation of traversable-wormhole-inspired quantum teleportation in a chaotic binary sparse SYK model
Moongul Byun, Keun-Young Kim, Hyeonsoo Lee
We report the experimental observation of holographically motivated quantum teleportation on a quantum processor, driven by the highly entangled, chaotic dynamics of a many-body sy…
Topology in Holographic Mean-Field Theory at Zero and Finite Temperature
Moongul Byun, Taewon Yuk, Young-Kwon Han +2
We investigate topological invariants in strongly interacting many-body systems within holographic mean-field theory (H-MFT) framework. Analytic expressions for retarded Green's fu…
Symmetric Tensor Coupling in Holographic Mean-Field Theory: Deformed Dirac Cones
Moongul Byun, Taewon Yuk, Sang-Jin Sin
We extend the holographic mean-field theory to rank-two symmetric tensor field as an external source coupled with fermion. We classify the roles of symmetric tensor coupling accord…
Correlation Functions and Stochastic Feynman Rules for Self-Interacting Scalar Fields
Moongul Byun
It is well known that perturbative solutions of the Langevin equation can be used to calculate correlation functions in stochastic quantization. However, this work is challenging d…
