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…
Generalized Real-space Chern Number Formula and Entanglement Hamiltonian
Ruihua Fan, Pengfei Zhang, Yingfei Gu
We generalize a real-space Chern number formula for gapped free fermions to higher orders. Using the generalized formula, we prove recent proposals for extracting thermal and elect…
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…
Periodically, Quasi-periodically, and Randomly Driven Conformal Field Theories (II): Furstenberg's Theorem and Exceptions to Heating Phases
Xueda Wen, Yingfei Gu, Ashvin Vishwanath +1
In this sequel (to [Phys. Rev. Res. 3, 023044(2021)], arXiv:2006.10072), we study randomly driven dimensional conformal field theories (CFTs), a family of quantum many-body…
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…
