TF1 Snowmass Report: Quantum gravity, string theory, and black holes
Daniel Harlow, Shamit Kachru, Juan Maldacena +35
We give an overview of the field of quantum gravity, string theory and black holes summarizing various white papers in this subject that were submitted as part of the Snowmass proc…
Snowmass White Paper: New ideas for many-body quantum systems from string theory and black holes
Mike Blake, Yingfei Gu, Sean A. Hartnoll +5
During the last two decades many new insights into the dynamics of strongly coupled quantum many-body systems have been obtained using gauge/gravity duality, with black holes often…
A two-way approach to out-of-time-order correlators
Yingfei Gu, Alexei Kitaev, Pengfei Zhang
Out-of-time-order correlators (OTOCs) are a standard measure of quantum chaos. Of the four operators involved, one pair may be regarded as a source and the other as a probe. A usua…
An obstacle to sub-AdS holography for SYK-like models
Pengfei Zhang, Yingfei Gu, Alexei Kitaev
We argue that "stringy" effects in a putative gravity-dual picture for SYK-like models are related to the branching time, a kinetic coefficient defined in terms of the retarded ker…
Floquet conformal field theories with generally deformed Hamiltonians
Ruihua Fan, Yingfei Gu, Ashvin Vishwanath +1
In this work, we study non-equilibrium dynamics in Floquet conformal field theories (CFTs) in 1+1D, in which the driving Hamiltonian involves the energy-momentum density spatially…
Notes on the complex Sachdev-Ye-Kitaev model
Yingfei Gu, Alexei Kitaev, Subir Sachdev +1
We describe numerous properties of the Sachdev-Ye-Kitaev model for complex fermions with flavors and a global U(1) charge. We provide a general definition of the charge in…
