How do Dirac Fermions Influence Material Properties?
Materials that host Dirac fermions often exhibit unique electronic properties. For example, in topological insulators—materials that act as insulators in their bulk but have conducting surface states—these surface states are protected by time-reversal symmetry and are described by Dirac fermions. This leads to robust, dissipationless edge currents, which could revolutionize low-power electronics and quantum computing.
