Minimum Hardware Requirements for Hybrid Quantum-Classical DMFT
Ben Jaderberg, Abhishek Agarwal, Karsten Leonhardt +2
We numerically emulate noisy intermediate-scale quantum (NISQ) devices and determine the minimal hardware requirements for two-site hybrid quantum-classical dynamical mean-field th…
Interplay of excitation transport and atomic motion in flexible Rydberg aggregates
Karsten Leonhardt
Strong resonant dipole-dipole interactions in flexible Rydberg aggregates enable the formation of exciton pulses, the interplay of atomic motion and electronic excitation transfer…
Exciton induced directed motion of unconstrained atoms in an ultracold gas
K. Leonhardt, S. Wüster, J. M. Rost
We demonstrate that through localised Rydberg excitation in a three-dimensional cold atom cloud atomic motion can be rendered directed and nearly confined to a plane, without spati…
Orthogonal flexible Rydberg aggregates
K. Leonhardt, S. Wüster, J. M. Rost
We study the link between atomic motion and exciton transport in flexible Rydberg aggregates, assemblies of highly excited light alkali atoms, for which motion due to dipole-dipole…
Switching Exciton Pulses Through Conical Intersections
K. Leonhardt, S. Wüster, J. M. Rost
Exciton pulses transport excitation and entanglement adiabatically through Rydberg aggregates, assemblies of highly excited light atoms, which are set into directed motion by reson…
Wegner estimate and localization for alloy-type models with sign-changing exponentially decaying single-site potentials
Karsten Leonhardt, Norbert Peyerimhoff, Martin Tautenhahn +1
We study Schrödinger operators on $L^2 (\RR^d)$ and $\ell^2(\ZZ^d)$ with a random potential of alloy-type. The single-site potential is assumed to be exponentially decaying but not…
