Cross-Correlations of Metric and Monopole Perturbations from Holographic Cosmology
Matheus Cravo, Juliana Z. Finotti, Horatiu Nastase
In this paper, we present the 1-loop calculation of the three-point function of the stress-energy tensor and two insertions of global currents, using…
Spacetime Duality Beyond Conformality
Jeff Murugan, Horatiu Nastase
We extend the spacetime duality programme of Burgess \textit{et.al.} to massive theories in 1+1 dimensions. For the massive scalar, a heat-kernel computation tracking three contrib…
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…
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…
3d QFT IR divergences as UV divergences in 4d Holographic Cosmology
Matheus Cravo, Horatiu Nastase
In this paper we consider IR divergences in a 3d toy model field theory for 4d holographic cosmology, and we analyze them by introducing a mass term in a way that preserves a certa…
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…
