Dirac matter
Okwu Dirac matter na-ezo aka na klas nke usoro ihe ndị dị n'ime ya nke enwere ike ịkọwa nke ọma site na usoro Dirac. Ọ bụ ezie na e mepụtara usoro Dirac n'onwe ya maka fermions, ihe fọrọ nke nta ka ọ bụrụ akụkụ dị n'ime ihe Dirac nwere ike ịbụ nke ọnụ ọgụgụ ọ bụla. N'ihi ya, enwere ike ịmata ọdịiche dị n'ihe Dirac na fermionic, bosonic ma ọ bụ anyonic Dirac. Ihe atụ ndị a ma ama nke ihe Dirac bụ Graphene, topological insulators, Dirac semimetals, Weyl semimetals.[1][2][3][4] A na-ekewapụta echiche dị irè nke usoro ndị dị otú ahụ site na nhọrọ a kapịrị ọnụ nke Dirac mass, ọsọ Dirac, matrices Dirac na curvature oge-oghere. Ọgwụgwọ zuru ụwa ọnụ nke klas nke ihe Dirac n'ihe gbasara echiche dị irè na-eduga na njirimara a na-ahụkarị n'ihe banyere njupụta nke steeti, ikike okpomọkụ na mgbasa nke adịghị ọcha.

Ndị otu klaasị nke okwu Dirac dị iche iche na okike. Otú ọ dị, ihe atụ nile nke ihe Dirac jikọtara ọnụ site na myirịta dị n'ime usoro algebra nke echiche dị irè na-akọwa ha.
