Quench-Probe Setup as Analyzer of Fractionalized Entanglement Spreading
Nicolas P. Bauer, Jan Carl Budich, Björn Trauzettel +1
We propose a novel spatially inhomogeneous setup for revealing quench-induced fractionalized excitations in entanglement dynamics. In this quench-probe setting, the region undergoi…

Symmetry protected exceptional points of interacting fermions
Robin Schäfer, Jan C. Budich, David J. Luitz
Non-hermitian quantum systems can exhibit spectral degeneracies known as exceptional points, where two or more eigenvectors coalesce, leading to a non-diagonalizable Jordan block.…
