Krylov Complexity Meets Confinement
Xuhao Jiang, Jad C. Halimeh, N. S. Srivatsa
In high-energy physics, confinement denotes the tendency of fundamental particles to remain bound together, preventing their observation as free, isolated entities. Interestingly,…
Quantum Chaos Diagnostics for non-Hermitian Systems from Bi-Lanczos Krylov Dynamics
Matteo Baggioli, Kyoung-Bum Huh, Hyun-Sik Jeong +3
In Hermitian systems, Krylov complexity has emerged as a powerful diagnostic of quantum dynamics, capable of distinguishing chaotic from integrable phases, in agreement with establ…
Complexity of PXP scars revisited
Pawel Caputa, Xuhao Jiang, Sinong Liu
We revisit a quantum quench scenario in which either a scarring or thermalizing initial state evolves under the PXP Hamiltonian. Within this framework, we study the time evolution…
Singular Value Decomposition and Its Blind Spot for Quantum Chaos in Non-Hermitian Sachdev-Ye-Kitaev Models
Matteo Baggioli, Kyoung-Bum Huh, Hyun-Sik Jeong +3
The study of chaos and complexity in non-Hermitian quantum systems poses significant challenges due to the emergence of complex eigenvalues in their spectra. Recently, the singular…
Warped CFT duals of the PlebaÅski-DemiaÅski family of solutions
Xuhao Jiang, Jianfei Xu
In this paper, we analyze the symmetry properties of the complete family of type D spacetimes generalized form the PlebaÅski-DemiaÅski solution in four dimensions holographically…
