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.…
