Many physicists believed it could not be done, but now a team in Germany has created a Bose–Einstein condensate (BEC) from photons. BECs are formed when identical bosons – particles with integer spin ...

The strong coupling treatment of the Fr¨ohlich-type polaronic system, based on a canonical
transformation and a standard Landau-Pekar type variational wave function, is applied to the
polaronic syst...

By measuring the density fluctuations in a highly elongated weakly interacting Bose gas, we observe and quantify the transition from the ideal gas to a quasi-condensate regime throughout the dimension...

Experimental observation of superfluidity in a microscopic cluster, M : (4He)x, of a
molecule (M) and x number of 4He atoms (with x ranging from 1 to many) is qualitatively
analyzed. It concludes th...

Physical reality of the existence of electron bubble in liquid 4He (or 3He) renders
a clear experimental evidence for a quantum particle (in an interacting environment as
seen by electron in liquid ...

We study the formation of a Bose-Einstein condensate in a cigar-shaped three-dimensional harmonic trap,induced by the controlled addition of an attractive “dimple” potential along the weak axis. In th...

Since the discovery of superfluidity in 4He and Landau’s phenomenological theory, the relationship between Bose condensation and superfluidity has been intensely debated. 4He is known by now to be bot...

17 May 2007，Physicists in the US say they have witnessed the trademark coherence of a Bose-Einstein condensate in a cooled system of quasiparticles known as "polaritons". Although similar claims have ...
