Determination of the ground state polarizability of Dy near 530 nm
Alexandre Journeaux, Maxime Lecomte, Julie Veschambre +3
Open-shell lanthanide atoms, and dysprosium in particular, combine a large ground-state angular momentum with dense electronic spectra, making their dynamical polarizability strong…
High-precision Penning-trap spectroscopy of the ground-state spin structure of HD+
Charlotte M. König, Matthew Bohman, Fabian Heiße +10
We present high-precision spectroscopy of the ground-state hyperfine structure of HD at 4~T. We determine the bound-electron factor, $g_{e,\mathrm{bound}} = -2.002\,278\,54…
Critical speed of a binary superfluid of light
Pierre-Élie Larré, Claire Michel, Nicolas Cherroret
We theoretically study the critical speed for superfluid flow of a two-dimensional miscible binary superfluid of light past a polarization-sensitive optical obstacle. This speed co…
Approaching Kasteleyn transition in frustrated quantum Heisenberg antiferromagnets
Katarina Karlova, Afonso Rufino, Taras Verkholyak +5
We show that the Kasteleyn transition, the abrupt proliferation of infinite strings of defects in classical dimer and related models, can also be relevant for frustrated 2d quantum…
Casimir effect with dielectric matter in salted water and implications at the cell scale
Larissa Inácio, Felipe S. S. Rosa, Astrid Lambrecht +2
The Casimir interaction in salted water contains a universal contribution of electromagnetic fluctuations that makes it of a longer range than previously thought. The universal con…
Acoustic horizons and the Hawking effect in polariton fluids of light
Elisabeth Giacobino, Maxime J. Jacquet
These lecture notes develop polariton fluids of light as programmable simulators of quantum fields on tailored curved spacetimes, with emphasis on acoustic horizons and the Hawking…
