Singular values of the Dirac operator at nonzero density
Takuya Kanazawa, Tilo Wettig, Naoki Yamamoto
At nonzero density the eigenvalues of the Dirac operator move into the complex plane, while its singular values remain real and nonnegative. In QCD-like theories, the singular-valu…

Banks-Casher-type relation for the BCS gap at high density
Takuya Kanazawa, Tilo Wettig, Naoki Yamamoto
We derive a new Banks-Casher-type relation which relates the density of complex Dirac eigenvalues at the origin to the BCS gap of quarks at high density. Our relation is applicable…
