Robust states of ultra-cold bosons in tilted optical lattices
Moritz Hiller, Hannah Venzl, Tobias Zech +3
We identify regular structures in the globally chaotic spectra of an interacting bosonic quantum gas in tilted periodic potentials. The associated eigenstates exhibit strong locali…

Simulability and regularity of complex quantum systems
Hannah Venzl, Andrew J. Daley, Florian Mintert +1
We show that the transition from regular to chaotic spectral statistics in interacting many-body quantum systems has an unambiguous signature in the distribution of Schmidt coeffic…

Quantum estimation of a damping constant
Hannah Venzl, Matthias Freyberger
We discuss an interferometric approach to the estimation of quantum mechanical damping. We study specific classes of entangled and separable probe states consisting of superpositio…
