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…

Benchmarking quantum master equations beyond ultraweak coupling
C. S. Tello Breuer, T. Becker, A. Eckardt
Recently, Nathan and Rudner derived a Gorini-Kossakowski-Sudarshan-Lindblad master equation from the Redfield equation. The claim is that the level of approximation is equal to tha…

Optimal form of time-local non-Lindblad master equations
Tobias Becker, André Eckardt
Time-local quantum master equations that describe open quantum systems beyond the limit of ultraweak system-bath coupling are often not of Gorini-Kossakowski-Sudarshan-Lindblad (GK…
