A magneto-gravitational trap for studies of gravitational quantum states

Autor: V. V. Nesvizhevsky, F. Nez, S. A. Vasiliev, E. Widmann, P. Crivelli, S. Reynaud, A. Yu. Voronin

Publikováno v: European Physical Journal C: Particles and Fields, Vol 80, Iss 6, Pp 1-10 (2020)

Abstract Observation time is the key parameter for improving the precision of measurements of gravitational quantum states of particles levitating above a reflecting surface. We propose a new method of long confinement in such states of atoms, anti-a

Temperature dependence of the probability of 'small heating' and total losses of UCNs on the surface of Fomblin oils of different molecular mass

Autor: S. M. Cherniavsky, E. V. Lychagin, A. Yu. Muzychka, G. V. Nekhaev, V. V. Nesvizhevsky, S. Reynaud, A. V. Strelkov, K. Turlybekuly

Publikováno v: European Physical Journal C: Particles and Fields, Vol 79, Iss 4, Pp 1-7 (2019)

Abstract We measured the temperature dependence of the probability of small heating and total losses of UCNs on the PFPE Fomblin Y surface with various molecular mass $$M_{{\bar{W}}}$$ MW¯ (2800, 3300, 6500 amu) in the temperature range of 100–300

Publikováno v: Physical Review Research, Vol 3, Iss 3, p 033037 (2021)

We measure the colloidal interaction between two silica microspheres in an aqueous solution in the distance range from 0.2 to 0.5μm with the help of optical tweezers. When employing a sample with a low salt concentration, the resulting interaction i

Light and temperature effects on δ11B and B / Ca ratios of the zooxanthellate coral Acropora sp.: results from culturing experiments

Autor: P. Louvat, M. McCulloch, P. Montagna, A. Juillet-Leclerc, S. Reynaud, E. Douville, D. Dissard

Publikováno v: Biogeosciences, Vol 9, Iss 11, Pp 4589-4605 (2012)

The boron isotopic composition (δ11B) of marine carbonates (e.g. corals) is increasingly utilised as a proxy for paleo-pH, with the strong correlation between δ11B of marine calcifiers and seawater pH now well documented. However, the potential rol

Light effects on the isotopic fractionation of skeletal oxygen and carbon in the cultured zooxanthellate coral, Acropora: implications for coral-growth rates

Autor: S. Reynaud, A. Juillet-Leclerc

Publikováno v: Biogeosciences, Vol 7, Iss 3, Pp 893-906 (2010)

Skeletal isotopic and metabolic measurements of the branching coral Acropora cultured in constant conditions and subjected to two light intensities were revisited. We individually compared the data recorded at low light (LL) and high light (HL) for 2

Prospects for Studies of the Free Fall and Gravitational Quantum States of Antimatter

Autor: G. Dufour, D. B. Cassidy, P. Crivelli, P. Debu, A. Lambrecht, V. V. Nesvizhevsky, S. Reynaud, A. Yu. Voronin, T. E. Wall

Publikováno v: Advances in High Energy Physics, Vol 2015 (2015)

Different experiments are ongoing to measure the effect of gravity on cold neutral antimatter atoms such as positronium, muonium, and antihydrogen. Among those, the project GBAR at CERN aims to measure precisely the gravitational fall of ultracold an
