Circuit complexity in interacting QFTs and RG flows

A Bhattacharyya, A Shekar, A Sinha - Journal of High Energy Physics, 2018 - Springer
We consider circuit complexity in certain interacting scalar quantum field theories, mainly
focusing on the ϕ 4theory. We work out the circuit complexity for evolving from a nearly …

Complexity= anything: singularity probes

E Jørstad, RC Myers, SM Ruan - Journal of High Energy Physics, 2023 - Springer
A bstract We investigate how the complexity= anything observables proposed by [1, 2] can
be used to investigate the interior geometry of AdS black holes. In particular, we illustrate …

The cosmological switchback effect

S Baiguera, R Berman, S Chapman… - Journal of High Energy …, 2023 - Springer
A bstract The volume behind the black hole horizon was suggested as a holographic dual
for the quantum computational complexity of the boundary state in AdS/CFT. This …

Time evolution of complexity: a critique of three methods

T Ali, A Bhattacharyya, SS Haque, EH Kim… - Journal of High Energy …, 2019 - Springer
A bstract In this work, we propose a testing procedure to distinguish between the different
approaches for computing complexity. Our test does not require a direct comparison …

Cosmological complexity

A Bhattacharyya, S Das, SS Haque, B Underwood - Physical Review D, 2020 - APS
We compute the quantum circuit complexity of the evolution of scalar curvature perturbations
on expanding backgrounds, using the language of squeezed vacuum states. In particular …

Holographic spacetimes as quantum circuits of path-integrations

T Takayanagi - Journal of High Energy Physics, 2018 - Springer
A bstract We propose that holographic spacetimes can be regarded as collections of
quantum circuits based on path-integrals. We relate a codimension one surface in a gravity …

Kasner eons with matter: holographic excursions to the black hole singularity

E Cáceres, ÁJ Murcia, AK Patra, JF Pedraza - Journal of High Energy …, 2024 - Springer
A bstract Recent work has shown that introducing higher-curvature terms to the Einstein-
Hilbert action causes the approach to a space-like singularity to unfold as a sequence of …

Holographic subregion complexity under a thermal quench

B Chen, WM Li, RQ Yang, CY Zhang… - Journal of High Energy …, 2018 - Springer
A bstract We study the evolution of holographic subregion complexity under a thermal
quench in this paper. From the subregion CV proposal in the AdS/CFT correspondence, the …
