Towards a Refinement of Krylov Complexity: Scrambling, Classical Operator Growth and Replicas
Hugo A. Camargo, Yichao Fu, Keun-Young Kim +1
We propose and test logarithmic Krylov (logK) complexity, an operator growth measure akin to Krylov complexity defined through a replica approach, as a viable probe of early-time o…
Toward Krylov-based holography in double-scaled SYK
Yichao Fu, Hyun-Sik Jeong, Keun-Young Kim +1
Building on the duality between Krylov complexity and geodesic length in Jackiw-Teitelboim and sine-dilaton gravity, we develop a precise holographic dictionary for quantities in t…
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…
Quantum Signatures of Chaos from Free Probability
Hugo A. Camargo, Yichao Fu, Viktor Jahnke +2
A classical dynamical system can be viewed as a probability space equipped with a measure-preserving time evolution map, admitting a purely algebraic formulation in terms of the al…
Higher-Order Krylov State Complexity in Random Matrix Quenches
Hugo A. Camargo, Yichao Fu, Viktor Jahnke +2
In quantum many-body systems, time-evolved states typically remain confined to a smaller region of the Hilbert space known as the . The time evolution can…
Wedge Holographic Complexity in Karch-Randall Braneworld
Yichao Fu, Keun-Young Kim
We investigate holographic complexities in the context of wedge holography, focusing specifically on black string geometry in AdS. The wedge spacetime is bounded by two end-of-…
Statistics and Complexity of Wavefunction Spreading in Quantum Dynamical Systems
Yichao Fu, Keun-Young Kim, Kunal Pal +1
We consider the statistics of the results of a measurement of the spreading operator in the Krylov basis generated by the Hamiltonian of a quantum system starting from a specified…
Exotic tetraquark states with
Yi-Chao Fu, Zhuo-Ran Huang, Zhu-Feng Zhang +1
We use the Laplace/Borel sum rules (LSR) and the finite energy/local duality sum rules (FESR) to investigate the non-strange and hidden-strange te…
