Spin-incoherent Mott-Thouless pumps
Ajesh Kumar, Urban F. P. Seifert, Erez Berg +1
A Thouless pump describes a system in which a quantized amount of charge is transported by one lattice spacing per cycle when the parameters of a Hamiltonian are varied slowly and…
Propelling Ferrimagnetic Domain Walls by Dynamical Frustration
Dennis Hardt, Reza Doostani, Sebastian Diehl +2
Many-particle systems driven out of thermal equilibrium can show properties qualitatively different from any thermal state. Here, we study a ferrimagnet in a weak oscillating magne…
Fractional Topological Charges in 2D Magnets
Nina del Ser, Imane El Achchi, Achim Rosch
Magnetic skyrmions and antiskyrmions are characterised by an integer topological charge , describing the winding of the magnetic orientation. Half-integer windin…
Gauged cooling of topological excitations and emergent fermions on quantum simulators
Gilad Kishony, Mark S. Rudner, Achim Rosch +1
Simulated cooling is a robust method for preparing low-energy states of many-body Hamiltonians on near-term quantum simulators. In such schemes, a subset of the simulator's spins (…
