An introduction to the SYK model
V Rosenhaus - Journal of Physics A: Mathematical and …, 2019 - iopscience.iop.org
Abstract The Sachdev–Ye–Kitaev (SYK) model is a strongly coupled, quantum many-body
system that is chaotic, nearly conformally invariant, and exactly solvable. This remarkable …

Circuit complexity in fermionic field theory
R Khan, C Krishnan, S Sharma - Physical Review D, 2018 - APS
We define and calculate versions of complexity for free fermionic quantum field theories in
1+ 1 and 3+ 1 dimensions, adopting Nielsen's geodesic perspective in the space of circuits …

Space-time in the SYK model
A bstract We consider the question of identifying the bulk space-time of the SYK model.
Focusing on the signature of emergent space-time of the (Euclidean) model, we explain the …

Synthetic fuzzballs: a linear ramp from black hole normal modes
S Das, C Krishnan, AP Kumar, A Kundu - Journal of High Energy Physics, 2023 - Springer
A bstract We consider a black hole with a stretched horizon as a toy model for a fuzzball
microstate. The stretched horizon provides a cut-off, and therefore one can determine the …
