One-Particle Density Matrix Framework for Mode-Shell Correspondence: Characterizing Topology in Amorphous Higher-Order Topological Insulators
Miguel F. MartÃnez, Miguel F. Martínez, Lucien Jezequel +3
We present a framework for characterizing higher-order topological phases directly from the one-particle density matrix, without any reference to an underlying Hamiltonian. Our app…
Quantum Hall Liquids Coupled to Dynamical Electromagnetism
T. H. Hansson, Qing-Dong Jiang, S. A. Kivelson +1
We investigate the effect on a Quantum Hall (QH) liquid of its coupling to 3+1 dimensional dynamical electromagnetism, which renders the system gapless. We calculate both the Hall…
When level repulsion fails: non-normality and chaos in open quantum systems
Caio B. Naves, Thomas Klein Kvorning, Jonas Larson
For Hamiltonian systems, level statistics provide a faithful diagnostic of quantum chaos. By analogy, the statistics of the Lindbladian spectrum are often used in open quantum syst…
Higher-Dimensional Information Lattice: Quantum State Characterization through Inclusion-Exclusion Local Information
Ian Matthias Flór, Claudia Artiaco, Thomas Klein Kvorning +1
We generalize the information lattice, originally defined for one-dimensional open-boundary chains, to characterize quantum many-body states in higher-dimensional geometries. In on…
Witnessing Short- and Long-Range Nonstabilizerness via the Information Lattice
Yuliya Bilinskaya, Miguel F. MartÃnez, Soumi Ghosh +3
We study nonstabilizerness on the information lattice, and demonstrate that noninteger local information directly indicates nonstabilizerness. For states with a clear separation of…
