Probing Spacetime Topology and Superposition with Accelerated Detectors
P. Poopathysankar, Lucas Hackl, Anwesha Chakraborty
We study entanglement harvested by Unruh DeWitt detectors following Rindler trajectories in compactified and superposed Minkowski spacetime. We consider different directions of acc…
Introducing SAGUARO -- Simulating IGM Evolution and Environments At High Resolution: Setup and First Results
Christopher Cain, Aloha Das, Anson D'Aloisio +7
Small-scale physics in the intergalactic medium (IGM) plays a crucial role in shaping the progress of cosmic reionization and several high-redshift observables that probe this peri…
Representation theory of inhomogeneous Gaussian unitaries
Jingqi Sun, Joshua Combes, Lucas Hackl
Gaussian unitaries, generated by quadratic Hamiltonians, are fundamental in quantum optics and continuous-variable computing. Their structures correspond to symplectic (bosons) and…
Random matrix prediction of average entanglement entropy in non-Abelian symmetry sectors
Anwesha Chakraborty, Lucas Hackl, Mario Kieburg
We study the average bipartite entanglement entropy of Haar-random pure states in quantum many-body systems with global symmetry, constrained to fixed total spin $…
Average entanglement entropy of a small subsystem in a constrained pure Gaussian state ensemble
Erik Aurell, Lucas Hackl, Mario Kieburg
We consider ensembles of pure Gaussian states parametrized by single-mode marginals and (optionally) specific mode-mode correlations. Such ensembles provide a model for the final s…
Entanglement harvesting in quantum superposed spacetime
Anwesha Chakraborty, Lucas Hackl, Magdalena Zych
We investigate the phenomenon of entanglement harvesting for a spacetime in quantum superposition, using two Unruh-DeWitt detectors interacting with a quantum scalar field where th…
Average mutual information for random fermionic Gaussian quantum states
Lucas Hackl, Mario Kieburg, Joel Maldonado
Studying the typical entanglement entropy of a bipartite system when averaging over different ensembles of pure quantum states has been instrumental in different areas of physics,…
Finite complexity of the de Sitter vacuum
Suddhasattwa Brahma, Lucas Hackl, Moatsem Hassan +1
The ER=EPR conjecture states that quantum entanglement between boundary degrees of freedom leads to the emergence of bulk spacetime itself. Although this has been tested extensivel…
Random pure Gaussian states and Hawking radiation
Erik Aurell, Lucas Hackl, Paweł Horodecki +2
A black hole evaporates by Hawking radiation. Each mode of that radiation is thermal. If the total state is nevertheless to be pure, modes must be entangled. Estimating the minimum…
Typical entanglement entropy in systems with particle-number conservation
Yale Yauk, Rohit Patil, Yicheng Zhang +2
We calculate the typical bipartite entanglement entropy in systems containing indistinguishable particles of any kind as a function of the total particle num…
Probing Hilbert space fragmentation and the block inverse participation ratio
Philipp Frey, David Mikhail, Stephan Rachel +1
We consider a family of quantum many-body Hamiltonians that show exact Hilbert space fragmentation in certain limits. The question arises whether fragmentation has implications for…
