Spectral and Krylov Complexity in Billiard Systems
Hugo A. Camargo, Viktor Jahnke, Hyun-Sik Jeong +2
In this work, we investigate spectral complexity and Krylov complexity in quantum billiard systems at finite temperature. We study both circle and stadium billiards as paradigmatic…
Krylov Complexity in Free and Interacting Scalar Field Theories with Bounded Power Spectrum
Hugo A. Camargo, Viktor Jahnke, Keun-Young Kim +1
We study a notion of operator growth known as Krylov complexity in free and interacting massive scalar quantum field theories in -dimensions at finite temperature. We consider t…
Balanced Partial Entanglement and Mixed State Correlations
Hugo A. Camargo, Pratik Nandy, Qiang Wen +1
Recently in Ref.\cite{Wen:2021qgx}, one of the authors introduced the balanced partial entanglement (BPE), which has been proposed to be dual to the entanglement wedge cross-sectio…
Q-curvature and Path Integral Complexity
Hugo A. Camargo, Pawel Caputa, Pratik Nandy
We discuss the interpretation of path integral optimization as a uniformization problem in even dimensions. This perspective allows for a systematical construction of the higher-di…
Long-distance entanglement of purification and reflected entropy in conformal field theory
Hugo A. Camargo, Lucas Hackl, Michal P. Heller +2
Quantifying entanglement properties of mixed states in quantum field theory via entanglement of purification and reflected entropy is a new and challenging subject. In this work, w…
Entanglement and Complexity of Purification in (1+1)-dimensional free Conformal Field Theories
Hugo A. Camargo, Lucas Hackl, Michal P. Heller +3
Finding pure states in an enlarged Hilbert space that encode the mixed state of a quantum field theory as a partial trace is necessarily a challenging task. Nevertheless, such puri…
Path integral optimization as circuit complexity
Hugo A. Camargo, Michal P. Heller, Ro Jefferson +1
Early efforts to understand complexity in field theory have primarily employed a geometric approach based on the concept of circuit complexity in quantum information theory. In a p…
Complexity as a novel probe of quantum quenches: universal scalings and purifications
Hugo A. Camargo, Pawel Caputa, Diptarka Das +2
We apply the recently developed notion of complexity for field theory to a quantum quench through a critical point in 1+1 dimensions. We begin with a toy model consisting of a quan…
