Shortcuts to adiabaticity (STA) are fast routes to the final results of slow, adiabatic changes
of the controlling parameters of a system. The shortcuts are designed by a set of analytical …

The control and manipulation of quantum systems without excitation are challenging, due to
the complexities in fully modeling such systems accurately and the difficulties in controlling …

We investigate the excitation of a quantum particle shuttled in a harmonic trap with weak
spring-constant colored noise. The Ornstein-Uhlenbeck model for the noise correlation …

We review methods to shuttle quantum particles fast and robustly. Ideal robustness amounts
to the invariance of the desired transport results with respect to deviations, noisy or …

The nonlinear dynamics of large ion clouds (N≥ 256 ions) trapped in radio-frequency (rf)
traps and coupled to laser cooling give rise to a bistable behavior of the temperature …

We propose a joint experimental and theoretical approach to measure the self-diffusion in a
laser-cooled trapped ion cloud where part of the ions are shelved in a long-lived dark state …

Radiofrequency multipole traps have been used for some decades in cold collision
experiments and are gaining interest for precision spectroscopy due to their low micromotion …

An interrogation protocol based on coherent population trapping in an N-level scheme
atomic system leads to dark resonances involving three different photons. An ensemble of …

Very long, one-dimensional ion chains are the basis for many applications, in particular in
quantum information processing, and reliable diagnostics are needed to quantify them. To …

The objective of the project is to perform high-resolution Doppler-free two-photon vibrational
spectroscopy of the H2+ molecular ion for accurate electron to proton mass ratio …
