Pulse engineering via projection of response functions at infinite nonlinear order
Lia Kley, Ludwig Mathey
Optimal control problems arise in a wide range of scientific disciplines, but the corresponding optimization algorithms often display a strong dependence on hyperparameters that si…
Fermionic Hamiltonian engineering with local control
Ãzgün Kum, Matthias Zipper, Ludwig Mathey +1
Quantum simulators enable the exploration of complex quantum phenomena in condensed-matter systems by reproducing their dynamics on controllable quantum devices. However, experimen…
Fluctuation amplification engineering in multimode Raman-cavity systems
H. P. Ojeda Collado, Ludwig Mathey
Parametric amplification is a key ingredient of a wide range of phenomena, from the classical to the quantum domain. Although such phenomena have been demonstrated in non-equilibri…
Coherent Optical Control of Electron Dynamics in Patterned Graphene Nanoribbons
Riek H. Rüstemeier, H. P. Ojeda Collado, Ludwig Mathey
The field of coherent electronics aims to advance electronic functionalities by utilizing quantum coherence. Here, we demonstrate a viable and versatile methodology for controlling…
Hybridization of the amplitude mode in a confined fermionic superfluid
Cesar R. Cabrera, René Henke, Lukas Broers +5
In phase transitions, spontaneous symmetry breaking results in a non-zero order parameter and two collective excitations: the Goldstone and the amplitude mode. These modes, which d…
Lamb-Dicke Dynamics of Interacting Rydberg Atoms Coupled to the Motion of an Optical Tweezer Array
Aslam Parvej, Ludwig Mathey
Neutral Rydberg atoms trapped in optical tweezer arrays provide a platform for quantum simulation and computation. In this work, we investigate the Lamb-Dicke dynamics of coupled R…
