From Single Particle to Superfluid Excitations in a Dissipative Polariton Gas

Benoît Marie Joseph Deveaud, Marcia Portella Oberli, Verena Kohnle

Using an angle-resolved heterodyne four-wave-mixing technique, we probe the low momentum excitation spectrum of a coherent polariton gas. The experimental results are well captured by the Bogoliubov transformation which describes the transition from single ...

Measurement of B→Ds(*)Kπ branching fractions

Mingkui Wang, Olivier Schneider, Chao Wang, Aurelio Bay, Vladislav Balagura, Remi Léandre Albert Louvot

We report a measurement of the exclusive B+ meson decay to the D-s(()K-)(+)pi(+) final state using 657 x 10(6) B (B) over bar pairs collected at the gamma(4S) resonance with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. We use D-s - ...

Photoexcitation and photoionization dynamics of doped liquid helium-4 nanodroplets

Evgeniy Loginov

The photoexcitation and photoionization dynamics of sodium atoms deposited on the surface of helium nanodroplets and aromatic molecules (aniline, phenol and toluene) embedded in the interior of droplets have been investigated by a variety of spectroscopic ...
