Detecting chiral edge states in the Hofstadter optical lattice.

Physical review letters

Goldman N, Beugnon J, Gerbier F.
PMID: 23004616
Phys Rev Lett. 2012 Jun 22;108(25):255303. doi: 10.1103/PhysRevLett.108.255303. Epub 2012 Jun 19.

We propose a realistic scheme to detect topological edge states in an optical lattice subjected to a synthetic magnetic field, based on a generalization of Bragg spectroscopy sensitive to angular momentum. We demonstrate that using a well-designed laser probe,...

Acid- and Au(i)-mediated synthesis of hexathymidine-DNA-heterocycle chimeras, an efficient entry to DNA-encoded libraries inspired by drug structures.

Chemical science

Škopić MK, Salamon H, Bugain O, Jung K, Gohla A, Doetsch LJ, Dos Santos D, Bhat A, Wagner B, Brunschweiger A.
PMID: 28507705
Chem Sci. 2017 May 01;8(5):3356-3361. doi: 10.1039/c7sc00455a. Epub 2017 Feb 28.

Libraries of DNA-tagged compounds are a validated screening technology for drug discovery. They are synthesized through combinatorial iterations of alternated coding and preparative synthesis steps. Thus, large chemical space can be accessed for target-based screening. However, the need to...

Time-compensated celestial orientation in the cricket Pteronemobius lineolatus.

Behavioural processes

Beugnon G.
PMID: 24925489
Behav Processes. 1987 Aug;15(1):109-15. doi: 10.1016/0376-6357(87)90036-2.

By varying the time difference between capture and release, we can show that swimming crickets Pteronemobius lineolatus are able to time compensate for the apparent azimuthal change of the sun's position.

Spatio-temporal learning by the ant ectatomma ruidum .

The Journal of experimental biology

Schatz B, Lachaud JP, Beugnon G.
PMID: 10377271
J Exp Biol. 1999 Jul;202:1897-907.

We tested, under field and laboratory conditions, whether the neotropical ant Ectatomma ruidum Roger can learn several associations between temporal and spatial changes in the daily pattern of food availability. Honey was shuffled between two or three feeding sites...

Synthetic aperture laser optical feedback imaging using a translational scanning with galvanometric mirrors.

Journal of the Optical Society of America. A, Optics, image science, and vision

Glastre W, Jacquin O, Hugon O, Guillet de Chatellus H, Lacot E.
PMID: 23201879
J Opt Soc Am A Opt Image Sci Vis. 2012 Aug 01;29(8):1639-47. doi: 10.1364/JOSAA.29.001639.

In this paper we present an experimental setup based on laser optical feedback imaging (LOFI) and on synthetic aperture with translational scanning by galvanometric mirrors for the purpose of making deep and resolved images through scattering media. We provide...

In vivo fluorescence lifetime optical projection tomography.

Biomedical optics express

McGinty J, Taylor HB, Chen L, Bugeon L, Lamb JR, Dallman MJ, French PM.
PMID: 21559145
Biomed Opt Express. 2011 Apr 26;2(5):1340-50. doi: 10.1364/BOE.2.001340.

We demonstrate the application of fluorescence lifetime optical projection tomography (FLIM-OPT) to in vivo imaging of lysC:GFP transgenic zebrafish embryos (Danio rerio). This method has been applied to unambiguously distinguish between the fluorescent protein (GFP) signal in myeloid cells...

Comparative study of autodyne and heterodyne laser interferometry for imaging.

Journal of the Optical Society of America. A, Optics, image science, and vision

Lacot E, Jacquin O, Roussely G, Hugon O, Guillet de Chatellus H.
PMID: 21045910
J Opt Soc Am A Opt Image Sci Vis. 2010 Nov 01;27(11):2450-8. doi: 10.1364/JOSAA.27.002450.

For given laser output power, object under investigation, and photodiode noise level, we have theoretically compared the signal-to-noise ratios of a heterodyne scanning imager based on a Michelson interferometer and of an autodyne setup based on the laser optical...

Quench-induced supercurrents in an annular Bose gas.

Physical review letters

Corman L, Chomaz L, Bienaimé T, Desbuquois R, Weitenberg C, Nascimbène S, Dalibard J, Beugnon J.
PMID: 25302899
Phys Rev Lett. 2014 Sep 26;113(13):135302. doi: 10.1103/PhysRevLett.113.135302. Epub 2014 Sep 26.

We create supercurrents in annular two-dimensional Bose gases through a temperature quench of the normal-to-superfluid phase transition. We detect the magnitude and the direction of these supercurrents by measuring spiral patterns resulting from the interference of the cloud with...

Sound Propagation in a Uniform Superfluid Two-Dimensional Bose Gas.

Physical review letters

Ville JL, Saint-Jalm R, Le Cerf É, Aidelsburger M, Nascimbène S, Dalibard J, Beugnon J.
PMID: 30339451
Phys Rev Lett. 2018 Oct 05;121(14):145301. doi: 10.1103/PhysRevLett.121.145301.

In superfluid systems several sound modes can be excited, such as, for example, first and second sound in liquid helium. Here, we excite running and standing waves in a uniform two-dimensional Bose gas and we characterize the propagation of...

Calcium Phosphate Bone Cements Including Sugar Surfactants: Part Two-Injectability, Adhesive Properties and Biocompatibility.

Addition of sugar surfactants, sucrose fatty acid esters and alkylpolyglucosides to a calcium phosphate cement, designed for bone reconstruction, is described. Thanks to their adsorption at the surface of the calcium phosphate particles, the sugar surfactants allowed a full...
