A 3-dimensional scanning trapped-ion probe
Tobias Sägesser, Shreyans Jain, Pavel Hrmo +6
Single-atom quantum sensors offer high spatial resolution and high sensitivity to electric and magnetic fields. Among them, trapped ions offer exceptional performance in sensing el…
State-dependent control of the motional modes of trapped ions using an integrated optical lattice
Alfredo Ricci Vasquez, Carmelo Mordini, Daniel Kienzler +1
In this work we study the interaction of trapped ions with a state-dependent, high-intensity optical lattice formed above an ion trap chip using integrated photonics. We use a sing…
Multi-zone trapped-ion qubit control in an integrated photonics QCCD device
Carmelo Mordini, Alfredo Ricci Vasquez, Yuto Motohashi +6
Multiplexed operations and extended coherent control over multiple trapping sites are fundamental requirements for a trapped-ion processor in a large scale architecture. Here we de…
Low-excitation transport and separation of high-mass-ratio mixed-species ion chains
Francesco Lancellotti, Stephan Welte, Matteo Simoni +6
We demonstrate low-excitation transport and separation of two-ion crystals consisting of one beryllium and one calcium ion, with a high mass ratio of . The full separation inv…
Control of an atomic quadrupole transition in a phase-stable standing wave
Alfredo Ricci Vasquez, Carmelo Mordini, Chloé Vérnière +6
Using a single calcium ion confined in a surface-electrode trap, we study the interaction of electric quadrupole transitions with a passively phase-stable optical standing wave fie…
Quantum-torque-induced breaking of magnetic interfaces in ultracold gases
Arturo Farolfi, Alessandro Zenesini, Dimitris Trypogeorgos +6
A rich variety of physical effects in spin dynamics arises at the interface between different magnetic materials. Engineered systems with interlaced magnetic structures have been u…
Single-shot reconstruction of the density profile of a dense atomic gas
C. Mordini, D. Trypogeorgos, L. Wolswijk +2
Partial transfer absorption imaging (PTAI) of ultracold atoms allows for repeated and minimally-destructive measurements of an atomic ensemble. Here, we present a reconstruction te…
Measurement of the Canonical Equation of State of a Weakly Interacting 3D Bose Gas
C. Mordini, D. Trypogeorgos, A. Farolfi +4
Using a multiple-image reconstruction method applied to a harmonically trapped Bose gas, we determine the equation of state of uniform matter across the critical transition point,…
Observation of magnetic solitons in two-component Bose-Einstein condensates
A. Farolfi, D. Trypogeorgos, C. Mordini +2
We experimentally investigate the dynamics of spin solitary waves (magnetic solitons) in a harmonically trapped, binary superfluid mixture. We measure the in-situ density of each p…
Optical visibility and core structure of vortex filaments in a bosonic superfluid
Franco Dalfovo, Russell N. Bisset, Carmelo Mordini +2
We use optical images of a superfluid consisting of a weakly interacting Bose-Einstein condensate of sodium atoms to investigate the structure of quantized three-dimensional vortex…
Production of large Bose-Einstein condensates in a magnetic-shield-compatible hybrid trap
Giacomo Colzi, Eleonora Fava, Matteo Barbiero +3
We describe the production of large Bose-Einstein condensates in a hybrid trap characterized by a weak magnetic field quadrupole and a tightly focused infrare…
Observation of Spin Superfluidity in a Bose Gas Mixture
E. Fava, T. Bienaimé, C. Mordini +5
The spin dynamics of a harmonically trapped Bose-Einstein condensed binary mixture of sodium atoms is experimentally investigated at finite temperature. In the collisional regime t…
Spin-Dipole Oscillation and Polarizability of a Binary Bose-Einstein Condensate near the Miscible-Immiscible Phase Transition
Tom Bienaimé, Eleonora Fava, Giacomo Colzi +6
We report on the measurement of the spin-dipole (SD) polarizability and of the frequency of the SD oscillation of a two-component Bose-Einstein condensate of sodium atoms occupying…
