Conformal field theory and the web of quantum chaos diagnostics
Jonah Kudler-Flam, Laimei Nie, Shinsei Ryu
We study three prominent diagnostics of chaos and scrambling in the context of two-dimensional conformal field theory: the spectral form factor, out-of-time-ordered correlators, an…
The negativity contour: a quasi-local measure of entanglement for mixed states
Jonah Kudler-Flam, Hassan Shapourian, Shinsei Ryu
In this paper, we study the entanglement structure of mixed states in quantum many-body systems using the , a local measure of entanglement that determ…
Derivation of holographic negativity in AdS/CFT
Yuya Kusuki, Jonah Kudler-Flam, Shinsei Ryu
We present a derivation of the holographic dual of logarithmic negativity in AdS/CFT that was recently conjectured in [Phys. Rev. D 99, 106014 (2019)]. This is given by the…
Quantum vs. classical information: operator negativity as a probe of scrambling
Jonah Kudler-Flam, Masahiro Nozaki, Shinsei Ryu +1
We consider the logarithmic negativity and related quantities of time evolution operators. We study free fermion, compact boson, and holographic conformal field theories (CFTs) as…
