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…
Realising the Symmetry-Protected Haldane Phase in Fermi-Hubbard Ladders
Pimonpan Sompet, Sarah Hirthe, Dominik Bourgund +10
Topology in quantum many-body systems has profoundly changed our understanding of quantum phases of matter. The paradigmatic model that has played an instrumental role in elucidati…
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…
Fractional corner charges in a 2D super-lattice Bose-Hubbard model
Julian Bibo, Izabella Lovas, Yizhi You +2
We study a two dimensional super-lattice Bose-Hubbard model with alternating hoppings in the limit of strong on-site interactions. We evaluate the phase diagram of the model around…
