Imaging magnetic nanoparticle distributions by atomic magnetometry-based susceptometry

Colombo, Simone ; Lebedev, Victor ; Tonyushkin, Alexey ; Pengue, Simone ; Weis, Antoine

In: IEEE Transactions on Medical Imaging, 2020, vol. 39, no. 4, p. 922–933

We introduce a Magnetic Particle Imaging Susceptometer (MPIS) that uses a high- sensitivity atomic magnetometer (AM) for recording the spatial distribution of fluid- suspended magnetic nanoparticles. We have evaluated the MPIS performance by one-dimensional scans of structured nanoparticle phantoms, demonstrating, in particular, resolutions of ≈2.5 mm prior to deconvolution and ≪1 mm after ...

Nonequilibrium solid-solid phase transition in a lattice of liquid jets

Croccolo, Fabrizio ; Castellini, Stefano ; Scheffold, Frank ; Vailati, Alberto

In: Physical Review E, 2018, vol. 98, no. 6, p. 063104

Solid-solid phase transitions are commonly encountered at the atomic scale in alloys and in superatomic mesoscopic systems of colloidal particles. Here we investigate a solid-solid phase transition occurring at the macroscopic scale between lattices of liquid jets with different symmetries generated by convection in a horizontal layer of a binary liquid mixture. In the absence of a shear...

Hypersatellite x-ray decay of $3d$ hollow-$K$-shell atoms produced by heavy-ion impact

Maillard, Yves-Patrick ; Dousse, Jean-Claude ; Hoszowska, Joanna ; Berset, Michel ; Mauron, Olivier ; Raboud, Pierre-Alexandre ; Kavčič, Matjaz ; Rzadkiewicz, J. ; Banaś, Dariusz ; Tökési, K.

In: Physical Review A, 2018, vol. 98, no. 1, p. 012705

We report on the radiative decay of double K-shell vacancy states produced in solid Ca, V, Fe, and Cu targets by impact with about 10 MeV/amu C and Ne ions. The resulting K hypersatellite x-ray emission spectra were measured by means of high- energy-resolution spectroscopy using a von Hamos bent crystal spectrometer. The experiment was carried out at the Philips variable energy cyclotron of...

Cesium alignment produced by pumping with unpolarized light

Shi, Yongqi ; Weis, Antoine

In: The European Physical Journal D, 2018, vol. 72, no. 4, p. 73

We demonstrate optical pumping on the four hyperfine components of the Cs D1 transition by unpolarized (UPL) resonant laser light. The evidence is based on the reduction of the absorption coefficients κ0 with increasing light power P in an uncoated Cs vapor cell with isotropic spin relaxation. For comparison we perform the same quantitative κ0(P) measurements with linearly-polarized light...
