Supersolids are fluid and solid at the same time. Physicists from Innsbruck and Geneva have for the first time investigated what happens when such a state is brought out of balance. They discovered a soft form of a solid of high interest for science. As the researchers led by Francesca Ferlaino...
Ultracold atoms used to verify 1963 prediction about 1D electrons
Physicists from Rice University and the University of Geneva have verified a key prediction from a 55-year-old theory about one-dimensional electronics that is increasingly relevant thanks to Silicon Valley’s inexorable quest for miniaturization.
The apparent inner calm of quantum materials
Transitions between different phases of matter are part of our day-to-day lives: when water freezes, for example, it passes from liquid to solid state. Some of these transitions may be of a different kind, resulting from so-called topological excitations that force all the particles to act in...
When superconductivity disappears in the core of a quantum tube
Predicting the behaviour of electrons in a material is not easily done. Physicists from the University of Geneva (UNIGE), ETH Zurich and EPFL replaced the electrons with ultra-cold neutral lithium atoms that they had circulated in a one-dimensional quantum tube. The scientists were then able to...
Nicolas Gisin’s and Thierry Giamarchi’s conferences at the French Academy of Sciences
Thierry Giamarchi and Nicolas Gisin gave a conference during the French Academy of Sciences colloquia, organized on the theme “Hundred years of quantum revolutions”.
The word of the academicians – Thierry Giamarchi explains the word “glass”
On the occasion of its 350th birthday, the French Academy of Sciences produced short films entitled “The word of the academicians”.
Topological properties of exotic matter – Interview with Thierry Giamarchi, CQFD, RTS la 1ère
Three British physicists have just won the 2016 Nobel Prize in Physics. These researchers have combined the beauty of mathematics with some very unusual physics and, in doing so, have theorized a new way of describing nature.
A step towards quantum electronics
Work of physicists at the University of Geneva (UNIGE), Switzerland, and the Swiss Federal Institute of Technology in Zurich (ETHZ), in which they connected two materials with unusual quantum-mechanical properties through a quantum constriction, could open up a novel path towards both a deeper...
