Time-independent counterdiabatic driving for emergent two-level subspaces in many-body systems
Simon Dengis, Peter Schlagheck
We show that geodesic motion in the Riemannian manifold of quantum states provides a direct route to time-independent counterdiabatic driving. Using the relation between the counte…

Vortex NOON states for rotation sensing
Simon Dengis, Nathan Dupont, Peter Schlagheck +1
We introduce a scheme to generate NOON states of few-body bosonic vortices and demonstrate their application as high-precision rotation sensors. Our approach is based on cold atoms…
