Electro-Optical Ion Trap for Experiments with Atom-Ion Quantum Hybrid Systems
Autor: Elia Perego, Lucia Duca, Carlo Sias
Publikováno v: Applied Sciences, Vol 10, Iss 7, p 2222 (2020)
In the development of atomic, molecular, and optical (AMO) physics, atom-ion hybrid systems are characterized by the presence of a new tool in the experimental AMO toolbox: atom-ion interactions. One of the main limitations in state-of-the-art atom-i

Design of a Littrow-type diode laser with independent control of cavity length and grating rotation
Autor: Carlo Sias, Elia Perego, Federico Berto, Lucia Duca
We present a novel extended-cavity diode laser (ECDL) based on a modified Littrow configuration. The coarse wavelength adjustment via the rotation of a diffraction grating is decoupled from the fine tuning of the external cavity modes by positioning

Prospects for single photon sideband cooling of optically trapped neutral atoms
Autor: Carlo Sias, Lucia Duca, Federico Berto, Elia Perego
We propose a novel cooling scheme for realising single photon sideband cooling on particles trapped in a state-dependent optical potential. We develop a master rate equation from an ab-initio model and find that in experimentally feasible conditions

Making ions cooler
Autor: Carlo Sias
Publikováno v: Nature Physics. 16:378-379
Cooling of trapped ions with a neutral buffer gas makes the study of atom–ion hybrid systems possible in the quantum regime. The new record low achieved opens the door to numerous opportunities, including full control over the atom–ion interactio

Towards a new atom-ion experiment in Italy
Autor: Marco De Pas, Elia Perego, Marco Pomponio, Lucia Duca, Amelia Detti, Claudio E. Calosso, Carlo Sias
Publikováno v: Quantum Information and Measurement (QIM) V: Quantum Technologies.
We report on an experiment that aims at realizing a novel atom-ion quantum mixture. In particular, we focus on two main technical advancements: a scalable control system and a new radiofrequency drive for Paul traps.

Paul traps are widely used to confine electrically charged particles like atomic and molecular ions by using an intense radiofrequency (RF) field, typically obtained by a voltage drop on capacitative electrodes placed in vacuum. We present a RF drive

Correlations in systems with spin degree of freedom are at the heart of fundamental phenomena, ranging from magnetism to superconductivity. The effects of correlations depend strongly on dimensionality, a striking example being one-dimensional (1D) e

We report on the experimental observation of a strongly interacting gas of ultracold two-electron fermions with orbital degree of freedom and magnetically tunable interactions. This realization has been enabled by the demonstration of a novel kind of
