Universal 1+2-body bound states in planar atomic wave guides
Ludovic Pricoupenko, Paolo Pedri
Shallow heteronuclear trimers are predicted for mixtures of two atomic species strongly trapped in a quasi two-dimensional atomic wave guide. The binding energies are functions of…
A Feshbach resonance in d-wave collisions
Q. Beaufils, A. Crubellier, T. Zanon +4
We analyse a narrow Feshbach resonance with ultra-cold chromium atoms colliding in d-wave. The resonance is made possible by dipole-dipole interactions, which couple an incoming $l…
Picosecond laser structuration under high pressures: observation of boron nitride nanorods
Luc Museur, Jean Pierre Petitet, Jean Pierre Michel +4
We report on picosecond UV-laser processing of hexagonal boron nitride (hBN) at moderately high pressures above 500 bar. The main effect is specific to the ambient gas and laser pu…
Negative-index media for matter-wave optics
J. Baudon, M. Hamamda, J. Grucker +4
We consider the extension of optical meta-materials to matter waves. We show that the generic property of pulsed comoving magnetic fields allows us to fashion the wave-number depen…
Defect-related photoluminescence of hexagonal boron nitride
Luc Museur, Feldbach Eduard, A. V. Kanaev
Photoluminescence of polycrystalline hexagonal boron nitride (hBN) was measured by means of time- and energy-resolved spectroscopy methods. The observed bands are related to DAP tr…
Radio-frequency induced ground state degeneracy in a Chromium Bose-Einstein condensate
Q. Beaufils, T. Zanon, R. Chicireanu +5
We study the effect of strong radio-frequency (rf) fields on a chromium Bose-Einstein condensate (BEC), in a regime where the rf frequency is much larger than the Larmor frequency.…
