Probing the Quantum Nature of Gravity in the Microgravity of Space
Ashmeet Singh
Conventionally, experiments probing the quantum nature of gravity were thought to be prohibitive due to the extremely high energy scales involved. However, recent and rapid advance…
Quantum Mereology: Factorizing Hilbert Space into Subsystems with Quasi-Classical Dynamics
Sean M. Carroll, Ashmeet Singh
We study the question of how to decompose Hilbert space into a preferred tensor-product factorization without any pre-existing structure other than a Hamiltonian operator, in parti…
Quantum State Reduction: Generalized Bipartitions from Algebras of Observables
Oleg Kabernik, Jason Pollack, Ashmeet Singh
Reduced density matrices are a powerful tool in the analysis of entanglement structure, approximate or coarse-grained dynamics, decoherence, and the emergence of classicality. It i…
Modeling Position and Momentum in Finite-Dimensional Hilbert Spaces via Generalized Pauli Operators
Ashmeet Singh, Sean M. Carroll
The finite entropy of black holes suggests that local regions of spacetime are described by finite-dimensional factors of Hilbert space, in contrast with the infinite-dimensional H…
Towards Space from Hilbert Space: Finding Lattice Structure in Finite-Dimensional Quantum Systems
Jason Pollack, Ashmeet Singh
Field theories place one or more degrees of freedom at every point in space. Hilbert spaces describing quantum field theories, or their finite-dimensional discretizations on lattic…
Mad-Dog Everettianism: Quantum Mechanics at Its Most Minimal
Sean M. Carroll, Ashmeet Singh
To the best of our current understanding, quantum mechanics is part of the most fundamental picture of the universe. It is natural to ask how pure and minimal this fundamental quan…
