Physical review letters

Lassen M, Delaubert V, Janousek J, Wagner K, Bachor HA, Lam PK, Treps N, Buchhave P, Fabre C, Harb CC.
PMID: 17359098
Phys Rev Lett. 2007 Feb 23;98(8):083602. doi: 10.1103/PhysRevLett.98.083602. Epub 2007 Feb 22.

We present the key elements required for continuous variable parallel quantum information protocols based on spatial multimode quantum correlations. We describe techniques for encoding, combining and detecting spatial quantum information with high efficiency in the individual transverse modes. Until...

Generation of higher order Gauss-Laguerre modes in single-pass 2nd harmonic generation.

PMID: 18958075
Opt Express. 2008 Oct 27;16(22):17952-61. doi: 10.1364/oe.16.017952.

We present a realistic method for dynamic simulation of the development of higher order modes in second harmonic generation. The deformation of the wave fronts due to the nonlinear interaction is expressed by expansion in higher order Gauss-Laguerre modes.

The Kepler spacecraft has been monitoring the light from 150,000 stars in its primary quest to detect transiting exoplanets. Here, we report on the detection of an eclipsing stellar hierarchical triple, identified in the Kepler photometry. KOI-126 [A, (B,...

Anisotropic photoconductivity and current deflection induced in Bi(12)SiO(20) crystals by a high-contrast interference pattern.

Optics letters

Kukhtarev N, Lyuksyutov S, Buchhave P, Caulfield HJ, Vasnetsov M.
PMID: 19881836
Opt Lett. 1996 Dec 01;21(23):1891-3. doi: 10.1364/ol.21.001891.

We have predicted and observed an anisotropic photocurrent induced in the cubic crystal Bi(12)SiO(20) by a high-contrast interference pattern. The transverse current detected when the interference pattern is tilted is caused by deflection of the direct current generated by...

Nature. 2012 Jun 13;486(7403):375-7. doi: 10.1038/nature11121.

The abundance of heavy elements (metallicity) in the photospheres of stars similar to the Sun provides a 'fossil' record of the chemical composition of the initial protoplanetary disk. Metal-rich stars are much more likely to harbour gas giant planets,...

A super-Earth transiting a nearby low-mass star.

Nature

Charbonneau D, Berta ZK, Irwin J, Burke CJ, Nutzman P, Buchhave LA, Lovis C, Bonfils X, Latham DW, Udry S, Murray-Clay RA, Holman MJ, Falco EE, Winn JN, Queloz D, Pepe F, Mayor M, Delfosse X, Forveille T.
PMID: 20016595
Nature. 2009 Dec 17;462(7275):891-4. doi: 10.1038/nature08679.

A decade ago, the detection of the first transiting extrasolar planet provided a direct constraint on its composition and opened the door to spectroscopic investigations of extrasolar planetary atmospheres. Because such characterization studies are feasible only for transiting systems...

A wide range, rapid scanning spectrometer for emission and absorption measurements.

Applied optics

Buchhave P, Church CH.
PMID: 20068967
Appl Opt. 1968 Nov 01;7(11):2200-4. doi: 10.1364/AO.7.002200.

A new, very wide spectral range, fast scanning spectrometer that combines high speed with good resolving power has been developed. The instrument operates with an f number in the vertical and horizontal plane of f/3 and f/17, respectively, and...

Since the discovery of the first extrasolar giant planets around Sun-like stars, evolving observational capabilities have brought us closer to the detection of true Earth analogues. The size of an exoplanet can be determined when it periodically passes in...

Stars hosting hot Jupiters are often observed to have high obliquities, whereas stars with multiple coplanar planets have been seen to have low obliquities. This has been interpreted as evidence that hot-Jupiter formation is linked to dynamical disruption, as...

Mol Neurodegener. 2010 Jan 14;5:2. doi: 10.1186/1750-1326-5-2.

BACKGROUND: Alzheimer's disease (AD) is associated with deposition of amyloid beta (Abeta) in the brain, which is reflected by low concentration of the Abeta1-42 peptide in the cerebrospinal fluid (CSF). There are at least 15 additional Abeta peptides in...
