Si l'on considère comme le fit Dirac que tous les états d'énergie sont occupés, ils ne peuvent pas être habités par d'autres fermions identiques. Particules échappant au principe d'exclusion Seuls les ...

Topological materials are revolutionizing semiconductor manufacturing, offering enhanced conductivity and efficiency for next ...

Les particules élémentaires de matière sont des fermions. Les fermions obéissent à la statistique de Fermi-Dirac ; ils sont donc de spin demi-entier ( 2k + 1 ) / 2 et sont soumis au principe ...

The International Nuclear and Radiological Event Scale (INES) is a tool for communicating the safety significance of nuclear and radiological events to the public. Member States use INES on a ...

Ferromagnetism is a form of magnetic ordering in which the intrinsic magnetic dipole moment, or spin, of electrons on each crystal-lattice site all align in the same direction. It is the ...

Designed with help from the audio experts at Dirac, a professional audio solution provider, the audio system delivers the most immersive, clear, and balanced sound experience you’ve ever heard on a PC ...

This proposal utilizes an extra dimension to localize fermions of definite chirality on one of two d-dimensional surfaces. The theory also contains a d-dimensional gauge field living on one of the ...
