International Team at Work: What Happened?

Under the leadership of Riccardo Comin from MIT, a team of researchers has reached a milestone by measuring, for the first time, the shape of a moving electron in a solid. This collaboration, bringing together experts from MIT and Cornell University, was facilitated by the pandemic, which encouraged remote work and allowed for unprecedented international synergy. Understanding the wave-like nature of electrons is essential for deciphering their properties in various materials, and this study represents a significant step in that direction.

Electrons, often described by “wave functions,” take on complex shapes in multidimensional spaces. These shapes are crucial for understanding the electronic properties of materials, and researchers have successfully measured them with unprecedented accuracy, thus opening up new perspectives for materials physics.

ARPES: A Game-Changing Technique

Angle-resolved photoemission spectroscopy (ARPES) played a central role in this discovery. This method analyzes the angles and spins of ejected electrons, providing a unique view of their quantum geometry. Quantum geometry transcends typical geometry and directly influences electron interactions, leading to surprising phenomena such as superconductivity observed in certain materials.

Kagome metals, for example, with their complex triangular structure, exhibit special characteristics attributed to this quantum geometry. The application of ARPES allowed for a deeper understanding of these structures and identification of new properties that could be leveraged in next-generation electronic devices.
