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…
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…
Quasiclassical theory of out-of-time-ordered correlators
Thomas R. Michel, Juan Diego Urbina, Peter Schlagheck
Out-of-time-ordered correlators (OTOCs), defined via the squared commutator of a time-evolving and a stationary operator, represent observables that provide useful indicators for c…
Quantum Enhancement of Thermalization
Yulong Qiao, Frank Großmann, 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…
