Emergent unitarity in de Sitter from matrix integrals
Jordan Cotler, Kristan Jensen
We study Jackiw-Teitelboim gravity with positive cosmological constant as a model for de Sitter quantum gravity. We focus on the quantum mechanics of the model at past and future i…
Spectral decoupling in many-body quantum chaos
Jordan Cotler, Nicholas Hunter-Jones
We argue that in a large class of disordered quantum many-body systems, the late time dynamics of time-dependent correlation functions is captured by random matrix theory, specific…
4-Manifold Invariants From Hopf Algebras
Julian Chaidez, Jordan Cotler, Shawn X. Cui
The Kuperberg invariant is a topological invariant of closed 3-manifolds based on finite-dimensional Hopf algebras. In this paper, we initiate the program of constructing 4-manifol…
Quantum Overlapping Tomography
Jordan Cotler, Frank Wilczek
It is now experimentally possible to entangle thousands of qubits, and efficiently measure each qubit in parallel in a distinct basis. To fully characterize an unknown entangled st…
Low-dimensional de Sitter quantum gravity
Jordan Cotler, Kristan Jensen, Alexander Maloney
We study aspects of Jackiw-Teitelboim (JT) quantum gravity in two-dimensional nearly de Sitter (dS) spacetime, as well as pure de Sitter quantum gravity in three dimensions. These…
Color Erasure Detectors Enable Chromatic Interferometry
Luo-Yuan Qu, Jordan Cotler, Fei Ma +7
By engineering and manipulating quantum entanglement between incoming photons and experimental apparatus, we construct single-photon detectors which cannot distinguish between phot…
