Are Weyl fermions truly massless?

The behavior of electrons' mass within a solid has a significant impact on the flow of electronic and heat energy. Weyl semimetals have emerged as a fascinating class of materials with unique properties. Physical and chemical ...

Quantum matter breakthrough: Tuning density waves

Scientists at EPFL have found a new way to create a crystalline structure called a "density wave" in an atomic gas. The findings can help us better understand the behavior of quantum matter, one of the most complex problems ...
