FPGA-based LQG controller and hardware-in-the-loop simulator implementation for nanomechanical systems
Vojtěch Mlynář, Johannes Berndorfer, Andreas Kugi +1
We present an open-source framework for real-time Linear Quadratic Gaussian (LQG) control and hardware-in-the-loop (HIL) simulation on the affordable Red Pitaya STEMlab FPGA platfo…
Identification and optimal control strategies for the transversal splitting of ultra--cold Bose gases
Nikolaus Würkner, Yevhenii Kuriatnikov, Karthikeyan Kumaran +5
Splitting a Bose--Einstein condensate (BEC) is a key operation in fundamental physics experiments and emerging quantum technologies, where precise preparation of well--defined init…
Feedback stabilization of a nanoparticle at the intensity minimum of an optical double-well potential
Vojtěch Mlynář, Salambô Dago, Jakob Rieser +5
In this work, we develop and analyze adaptive feedback control strategies to stabilize and confine a nanoparticle at the unstable intensity minimum of an optical double-well potent…
Optimal Sensing of Momentum Kicks with a Feedback-Controlled Nanomechanical Resonator
Kaspar Schmerling, Hajrudin Bešić, Andreas Kugi +2
External disturbances exciting a mechanical resonator can be exploited to gain information on the environment. Many of these interactions manifest as momentum kicks, such as the re…
Nonlinear feedback stabilisation and stochastic disturbance suppression of actively Q-switched lasers
Lukas Tarra, Andreas Deutschmann-Olek, Andreas Kugi
Actively Q-switched lasers are widely used tools which are required to produce stable output pulse energies for many applications. In this paper, a model-based control concept for…
Optimal control of quasi-1D Bose gases in optical box potentials
Andreas Deutschmann-Olek, Katharina Schrom, Nikolaus Würkner +3
In this paper, we investigate the manipulation of quasi-1D Bose gases that are trapped in a highly elongated potential by optimal control methods. The effective meanfield dynamics…
Iterative shaping of optical potentials for one-dimensional Bose-Einstein condensates
Andreas Deutschmann-Olek, Mohammadamin Tajik, Martino Calzavara +3
The ability to manipulate clouds of ultra-cold atoms is crucial for modern experiments on quantum manybody systems and quantum thermodynamics as well as future metrological applica…
