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…

Typical entanglement in anyon chains: Page curves beyond Lie group symmetries
Yale Yauk, Lucas Hackl, Alexander Hahn
We study bipartite entanglement statistics in one-dimensional anyon chains, whose Hilbert spaces are constrained by fusion rules of unitary pre-modular categories. Our setup genera…

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…
