Thouless Pumps and Bulk-Boundary Correspondence in Higher-Order Symmetry-Protected Topological Phases
Julian F. Wienand, Friederike Horn, Monika Aidelsburger +2
The bulk-boundary correspondence relates quantized edge states to bulk topological invariants in topological phases of matter. In one-dimensional symmetry-protected topological sys…
Skeleton of Matrix-Product-State-Solvable Models Connecting Topological Phases of Matter
Nick G. Jones, Julian Bibo, Bernhard Jobst +3
Models whose ground states can be written as an exact matrix product state (MPS) provide valuable insights into phases of matter. While MPS-solvable models are typically studied as…
Quotient symmetry protected topological phenomena
Ruben Verresen, Julian Bibo, Frank Pollmann
Topological phenomena are commonly studied in phases of matter which are separated from a trivial phase by an unavoidable quantum phase transition. This can be overly restrictive,…
Fractonic critical point proximate to a higher-order topological insulator: How does UV blend with IR?
Yizhi You, Julian Bibo, Taylor L. Hughes +1
We propose an unconventional topological quantum phase transition connecting a higher-order topological insulator (HOTI) and a featureless Mott insulator sharing the same symmetry…
Fracton Critical Point in Higher-Order Topological Phase Transition
Yizhi You, Julian Bibo, Frank Pollmann +1
The theory of quantum phase transitions separating different phases with distinct symmetry patterns at zero temperature is one of the foundations of modern quantum many-body physic…
Higher-Order Entanglement and Many-Body Invariants for Higher-Order Topological Phases
Yizhi You, Julian Bibo, Frank Pollmann
We discuss how strongly interacting higher-order symmetry protected topological (HOSPT) phases can be characterized from the entanglement perspective: First, we introduce a topolog…
