Time-independent counterdiabatic driving for emergent two-level subspaces in many-body systems
Simon Dengis, Peter Schlagheck
The paper demonstrates that constant‑speed geodesic motion in the quantum state manifold leads to a time‑independent counterdiabatic Hamiltonian for emergent two‑level subspaces, a…
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…
Scrambling at the genesis of chaos
Thomas R. Michel, Mathias Steinhuber, Juan Diego Urbina +1
The presence of chaos in classical Hamiltonian systems is witnessed by its maximal Lyapunov exponent, that quantifies the instability of motion through the exponential growth of in…
Multimode NOON-state generation with ultracold atoms via geodesic counterdiabatic driving
Simon Dengis, Sandro Wimberger, Peter Schlagheck
We present a protocol for the generation of NOON states with ultracold atoms, leveraging the Bose-Hubbard model in the self-trapping regime. By the means of an optimized adiabatic…
Quantum Enhancement of Thermalization
Yulong Qiao, Frank GroÃmann, Peter Schlagheck +1
Equilibrium properties of many-body systems with a large number of degrees of freedom are generally expected to be described by statistical mechanics. Such expectations are closely…
Accelerated creation of NOON states with ultracold atoms via counterdiabatic driving
Simon Dengis, Sandro Wimberger, Peter Schlagheck
A quantum control protocol is proposed for the creation of NOON states with ultracold bosonic atoms on two modes, corresponding to the coherent superposition $\vert N,0\rangle…
