Towards a black body for near-field thermal radiation
S. -A. Biehs, M. Tschikin, P. Ben-Abdallah
We study the near-field heat exchange between hyperbolic materials and demonstrate that these media are able to support broadband frustrated modes which transport heat by photon tu…
Direct observation of quantum phonon fluctuations in a one dimensional Bose gas
Julien Armijo
We report the first direct observation of collective quantum fluctuations in a continuous field. Shot-to-shot atom number fluctuations in small sub-volumes of a weakly interacting…
Radiative cooling of nanoparticles close to a surface
M. Tschikin, S. -A. Biehs, P. Ben-Abdallah +1
We study the radiative cooling of polar and metallic nanoparticles immersed in a thermal bath close to a partially reflecting surface. The dynamics of relaxation is investigated at…
Matter Wave Transport and Anderson Localization in Anisotropic 3D Disorder
Marie Piraud, Luca Pezzé, Laurent Sanchez-Palencia
We study quantum transport in anisotropic 3D disorder and show that non rotation invariant correlations can induce rich diffusion and localization properties. For instance, structu…
Effect of disorder close to the superfluid transition in a two-dimensional Bose gas
Baptiste Allard, Thomas Plisson, Markus Holzmann +4
We experimentally study the effect of disorder on trapped quasi two-dimensional (2D) 87Rb clouds in the vicinity of the Berezinskii-Kosterlitz-Thouless (BKT) phase transition. The…
Statistical properties of spontaneous emission near a rough surface
Svend-Age Biehs, Jean-Jacques Greffet
We study the lifetime of the excited state of an atom or molecule near a plane surface with a given random surface roughness. In particular, we discuss the impact of the scattering…
