Spectral Topology and Universal Krylov Dynamics

Jeff Murugan, Hendrik J. R. Van Zyl, Masataka Watanabe

The leading asymptotic growth of Lanczos coefficients is controlled by spectral tails and furnishes a coarse classification of Krylov dynamics. We show that the \textit{global topo…

On the Universality of Probe Complexity in SYM

Eric L. Graef, Jeff Murugan, Horatiu Nastase +1

We investigate Krylov complexity for single-trace operators dual to open strings attached to giant gravitons in planar super Yang-Mills theory. We show that in prot…

Krylov complexity from a simple quantum mechanical model for a radiating black hole

Eric L Graef, Jeff Murugan, Horatiu Nastase +1

We investigate Krylov complexity in a simple quantum mechanical model describing a black hole coupled to its radiation. The model is constructed as a simplified ``mini-BMN" matrix…

A Schwinger-Keldysh Formulation of Semiclassical Operator Dynamics

Jeff Murugan, Hendrik J. R. van Zyl

In this work we develop a real-time Schwinger-Keldysh formulation of Krylov dynamics that treats Krylov complexity as an in-in observable generated by a closed time contour path in…

A Quantum Computational Perspective on Spread Complexity

Cameron Beetar, Eric L Graef, Jeff Murugan +2

We establish a direct connection between spread complexity and quantum circuit complexity by demonstrating that spread complexity emerges as a limiting case of a circuit complexity…

Massive fields in AdS from Constructive Holography

Robert de Mello Koch, Pratik Roy, Hendrik J. R. Van Zyl

Collective field theory offers a constructive framework for exploring the AdS/CFT duality. In this article, we focus on constructing rotations within the light-front quantized coll…
