Discrete antiferromagnetic spin-wave excitations in the giant ferric wheel Fe18
J. Ummethum, J. Nehrkorn, S. Mukherjee +8
The low-temperature elementary spin excitations in the AFM molecular wheel Fe18 were studied experimentally by inelastic neutron scattering and theoretically by modern numerical me…

Staying adiabatic with unknown energy gap
J. Nehrkorn, S. Montangero, A. Ekert +3
We introduce an algorithm to perform an optimal adiabatic evolution that operates without an apriori knowledge of the system spectrum. By probing the system gap locally, the algori…
