Photonics is a branch of technology development that specializes in the creation of devices that can generate, detect or manipulate light. Recently, researchers at Université Paris-Saclay coined a new term for a new photonics sub-field called non-Euclidean photonics.

Study predicts the behavior of a Kondo cloud in a superconductor
In recent years, many physicists worldwide have been investigating the behavior of hybrid nanostructures. These are systems that are typically made up of two or more materials. Special attention in this class of structures is paid to magnetic impurities interacting...
Study explores the origin of clonal dominance in excitable cell networks
Clonal dominance is a phenomenon that occurs when descendants (i.e., clones) of one or more founder cells in an organism contribute disproportionally to the system's final structure as the tissue grows. This phenomenon is associated with numerous biological processes,...
Study shows what happens to apparent horizons when binary black holes merge
Binary black hole mergers are fascinating cosmological events, which have been theorized to be the among the strongest sources of gravitational waves in the universe. While astrophysicists have carried out extensive research focusing on these events, many questions...
A new method to measure quantum entanglement in a nuclear spin ensemble
One of the primary objectives of quantum physics studies is to measure the quantum states of large systems composed of many interacting particles. This could be particularly useful for the development of quantum computers and other quantum information processing...
Study reports the ferroelectric switching of spin-to-charge conversion in germanium telluride
Spintronic devices, a class of architectures that can store or transfer information by leveraging the intrinsic spin of electrons, have been found to be highly promising, both in terms of speed and efficiency. So far, however, the development of these devices has been...
A strategy to control the spin polarization of electrons using helium
Spintronics, also known as spin electronics, is a research field that explores how the intrinsic spin of electrons and its magnetic moment can be exploited by devices. Spintronic devices are promising for a wide range of applications, particularly for efficiently...
The observation of correlated states and superconductivity in twisted trilayer graphene
When two layers of graphene or of other two-dimensional (2D) materials are stacked on top of each other with a small angle misalignment, the crystal lattices produced by each layer are spatially 'out of synch'. This results in a unique structural pattern known as...
Researchers observe interband collective excitations in twisted bilayer graphene
Twisted bilayer graphene is a carbon-based, two-dimensional (2D) material comprising two graphene layers. Although many scientists have recently started exploring its potential for superconductivity and magnetism, so far, there have been very few optical studies...
Researchers observe translation symmetry breaking in twisted bilayer graphene
Magic-angle twisted bilayer graphene is a material made of two sheets of graphene placed on top of each other, with one sheet twisted at precisely 1.05 degrees with respect to the other. This material has been found to be a very promising platform for studying...
