Weyl Semimetals Host Exotic Electron Behavior
Weyl semimetals feature special points where electron bands cross.
These crossings create Weyl fermions with unique properties.
Researchers observe Fermi arc surface states in these materials.
In addition, they show strong responses to magnetic fields.
Recent studies in 2026 reveal new Weyl-Kondo semimetals.
These emerge from quantum criticality and heavy fermion systems.
They expand our understanding of topological semimetals.
Majorana Fermions Promise Robust Quantum Bits
Majorana fermions act as their own antiparticles.
They appear at the boundaries of certain topological materials.
Moreover, they enable fault-tolerant quantum computing.
These particles resist local noise and decoherence effectively.
