QCD的动量空间拓扑

Momentum space topology of QCD

M. A. Zubkov

摘要:

讨论了夸克物质作为拓扑物质的可能性。我们考虑了强子相(HP)、夸克-胶子等离子体相(QGP)和假设的色味锁定(CFL)相.在这些阶段中,我们确定了动量空间中的相关拓扑不变量。形式主义的发展,它涉及到那些不变量和无质量费米子,驻留在涡旋和相间。这种形式主义说明了CFL阶段的旋涡的例子。

英文摘要:

We discuss the possibility to consider quark matter as the topological material. We consider hadronic phase (HP), the quark - gluon plasma phase (QGP), and the hypothetical color - flavor locking (CFL) phase. In those phases we identify the relevant topological invariants in momentum space. The formalism is developed, which relates those invariants and massless fermions that reside on vortices and at the interphases. This formalism is illustrated by the example of vortices in the CFL phase.
