Abstract (AI)
In recent years many three-dimensional crystals have been discovered whose low energy electronic properties are described by the Dirac or Weyl equations for relativistic fermions. This leads to many unusual physical properties and potentially to new applications. This review explains the theory behind these developments, their material realizations, and the current experimental status.
Key Findings
1
Dirac and Weyl semimetals exhibit unusual physical properties arising from their relativistic low-energy electronic structure.
2
The review covers the theoretical foundations, material realizations, and current experimental status of three-dimensional Dirac and Weyl semimetals.
3
These materials may enable new applications based on their unconventional electronic properties.
4
Three-dimensional crystals have been discovered whose low-energy electronic excitations are described by relativistic Dirac or Weyl equations.
