Out-of-time-order correlators and Lyapunov exponents in sparse SYK
Elena Cáceres, Tyler Guglielmo, Brian Kent +1
We use a combination of analytical and numerical methods to study out-of-time order correlators (OTOCs) in the sparse Sachdev-Ye-Kitaev (SYK) model. We find that at a given order o…
Checking volume-law entropy with HRT surfaces
Tyler Guglielmo, Phuc Nguyen
We check formally that the Hubeny-Rangamani-Takayanagi prescription for holographic entanglement entropy -- when applied to a static black brane spacetime and to a wide class of su…
Quantum chaos in a weakly-coupled field theory with nonlocality
Willy Fischler, Tyler Guglielmo, Phuc Nguyen
In order to study the chaotic behavior of a system with non-local interactions, we will consider weakly coupled non-commutative field theories. We compute the Lyapunov exponent of…
Speeding up the spread of quantum information in chaotic systems
Stefan Eccles, Willy Fischler, Tyler Guglielmo +2
We explore the effect of introducing mild nonlocality into otherwise local, chaotic quantum systems, on the rate of information spreading and associated rates of entanglement gener…
