Organic molecules for quantum detection
A Franco-British research team has developed a luminous organic molecule capable of revealing its quantum spin state by a simple change of colour, a result that opens up a new …
Why do some foams hold up better than others? An answer from space!
In a long-term study carried out on the International Space Station (ISS), researchers were able to study precisely the physico-chemical factors influencing the long-term stability of foams by avoiding gravity-induced …
International Physics Olympiad 2025 in LPS
The Solid State Physics Laboratory (LPS) (Paris-Saclay University and CNRS) was pleased to welcome participants of the 2025 International Physics Olympiad, held this year in Paris. #IPhO2025 Delegations from Cuba, …
Nickelates: A Stabilized Superconducting State Without Doping
Cuprates, copper-based oxides, are renowned for their high-temperature superconducting properties. Doping—the process of introducing foreign atoms (dopants) into the material’s structure—modulates their electronic properties and promotes superconductivity by altering the …
Directing Nanoscale Heat Flow in Nanocrystal-Based Metamaterials
Les nanocristaux se sont massivement imposés comme une solution polyvalente pour la fabrication d’une nouvelle génération de dispositifs opto-électroniques comme les LEDs ou les cellules photovoltaïques. Des travaux récents suggèrent …
Shearing of a Charge Density Wave Observed Using an XFEL Source

Quantum Confined Luminescence in Two Dimensions
Researchers at the Solid State Physics Laboratory (CNRS/Université Paris-Saclay) and their collaborators have developed a new light source: two-dimensional quantum dots created in monolayers of transition metal dichalcogenides. The field …
No need to strike while the iron is… small!
CNRS scientists have studied the evolution of the shape of gold nano-tetrapods and have revealed a two-stage kinetics: the four arms – initially pointed – quickly become blunt, before beginning …
Hund’s coupling mediated multi-channel quantum phase transition of a single magnetic impurity in Fe(Se,Te)
Sub-gap states generated by single spins in a superconductor can be used as building blocks for quantum devices. Physicists at the Laboratoire physique des solides (CNRS/Université Paris-Saclay) have uncovered that …
