Information lattice approach to the metal-insulator transition
William Skoglund, Elton Giacomelli, Yiqi Yang +2
Correlation functions and correlation lengths are frequently used to describe phase transitions in quantum systems, but they require an explicit choice of observables. The recently…
Symmetry fractionalization, mixed-anomalies and dualities in quantum spin models with generalized symmetries
Heidar Moradi, Ömer M. Aksoy, Jens H. Bardarson +1
We investigate the gauging of higher-form finite Abelian symmetries and their sub-groups in quantum spin models in spatial dimensions and 3. Doing so, we naturally uncover ga…
Distinguishing localization from chaos: challenges in finite-size systems
D. A. Abanin, J. H. Bardarson, G. De Tomasi +7
We re-examine attempts to study the many-body localization transition using measures that are physically natural on the ergodic/quantum chaotic regime of the phase diagram. Using s…
Sharp entanglement thresholds in the logarithmic negativity of disjoint blocks in the transverse-field Ising chain
Younes Javanmard, Daniele Trapin, Soumya Bera +2
Entanglement has developed into an essential concept for the characterization of phases and phase transitions in ground states of quantum many-body systems. In this work, we use th…
Finding purifications with minimal entanglement
Johannes Hauschild, Eyal Leviatan, Jens H. Bardarson +3
Purification is a tool that allows to represent mixed quantum states as pure states on enlarged Hilbert spaces. A purification of a given state is not unique and its entanglement s…
Unified bulk-boundary correspondence for band insulators
Jun-Won Rhim, Jens H. Bardarson, Robert-Jan Slager
The bulk-boundary correspondence, a topic of intensive research interest over the past decades, is one of the quintessential ideas in the physics of topological quantum matter. Nev…
