Gravitational Algebras with Two Areas
Xuchen Cao, Thomas Faulkner, Zhencheng Wang
We study gravitational algebras on spacetimes with two extremal surfaces. In the example of a long wormhole with two asymptotic AdS boundaries and two compact extremal surfaces, we…
Single-Sided Black Holes in Double-Scaled SYK Model and No Man's Island
Xuchen Cao, Ping Gao
We study a single-sided black hole with an end-of-the-world (EoW) brane behind the horizon in the double-scaled SYK (DSSYK). The new Hamiltonian is a deformation of the original DS…
Ramp from Replica Trick
Xuchen Cao, Thomas Faulkner
We compute the spectral form factor of the modular Hamiltonian associated to the reduced density matrix of a Haar random state. A ramp is demonstrated and we find an an…
Topological Field Theories of Three-Dimensional Rotation Symmetric Insulators: Coupling Curvature and Electromagnetism
Julian May-Mann, Mark R. Hirsbrunner, Xuchen Cao +1
Quantized responses are important tools for understanding and characterizing the universal features of topological phases of matter. In this work, we consider a class of topologica…
