Excitons are pairs of electrons and holes inside a solid material that together behave like a single particle. It has long been suspected that when many such excitons exist in the same piece of matter, they can form a Bose-Einstein condensate. However, actually proving that Bose-Einstein condensation of excitons occurs in any real material has been a challenge for physicists for decades. Experimental evidence of such a state has been found!
A comment about the discovery: Spontaneous Bose-Einstein condensation of excitons

“This year’s Laureates opened the door on an unknown world where matter exists in strange states. The Nobel Prize in Physics 2016 is awarded with one half to David J. Thouless, University of Washington, Seattle, and the other half to F. Duncan M. Haldane, Princeton University, and J. Michael Kosterlitz, Brown University, Providence. Their discoveries have brought about breakthroughs in the theoretical understanding of matter’s mysteries and created new perspectives on the development of innovative materials.
The three Laureates’ use of topological concepts in physics was decisive for their discoveries. Topology is a branch of mathematics that describes properties that only change step-wise. Using topology as a tool, they were able to astound the experts. ”

We arrived at the end of the 7th International Conference The New Generation in Strongly Correlated Electrons Systems 2016.
It was a nice week rich of nice talks and fruitful and interesting discussions. Here you can find some of the nice talks presented during the week!
Four new chemical elements will take their places in the periodic table, the International Union of Pure and Applied Chemistry (IUPAC) announced last week. IUPAC verified the discoveries of elements 113, 115, 117, and 118, which complete the periodic table’s seventh row.
Quite interesting reports.
Just few personal notes:
Poor italian research health
The fifth transparency of the Consolidator Grants about the “nationals in own country and abroad” points out essentially two aspects: a very good education + a bad research environment.

Not good…but not that bad as I had expected!
