Quantum Materials: the Discovery of a New State of Matter with Chiral Properties

An international research group has discovered a new state of matter characterized by the existence of a quantum phenomenon called chiral current. These currents are generated on an atomic scale by a cooperative movement of electrons, unlike conventional magnetic materials whose properties originate from the quantum characteristic of an electron known as spin and their […]

Hidden Patterns in a Weyl Kagome Semimetal

The study centres on Co3Sn2S2, a magnetic Weyl kagome system. The kagome lattice, a hexagonal network of interconnected triangles, has been a subject of intense scientific interest due to its distinctive geometry and potential for hosting topological phases. Co3Sn2S2, in particular, exhibits intriguing properties such as high-electron density flat bands, Dirac states, and the presence

Quantum materials: measuring the topological wrapping of electrons

In an international collaboration involving experiments and theory, the topological wrapping of electrons in matter, which refers to the curvature of the space in which they exist and move, has been measured in a new class of materials. This new discovery could lead to a deeper understanding of quantum materials, which are materials where the
