Identification and properties of topological states in the bulk of quasicrystals
Frode Balling-Ansø, Jeppe Lykke Krogh, Ella Elisabeth Lassen +1
In contrast to the usual bulk-boundary correspondence, topological states localized within the bulk of the system have been numerically identified in quasicrystalline structures, t…

Experimental protocol for observing single quantum many-body scars with transmon qubits
Peter Græns Larsen, Anne E. B. Nielsen, André Eckardt +1
Quantum many-body scars are energy eigenstates which fail to reproduce thermal expectation values of local observables, in systems where the rest of the many-body spectrum fulfils…

Phase Transitions in Quantum Many-Body Scars
Peter Græns Larsen, Anne E. B. Nielsen
We propose a type of phase transition in quantum many-body systems, which occurs in highly excited quantum many-body scar states, while most of the spectrum is largely unaffected.…
