一维无质量Dirac算子的共振

Resonances for 1D massless Dirac operators

Alexei Iantchenko, Evgeny Korotyaev

摘要:

本文考虑实直线上的一维无质量Dirac算子,其势为紧支势。我们把共振态作为散射矩阵的极点或等价地作为修正Fredholm行列式的零点来研究。我们得到了共振态的下列性质:1)计数函数的渐近性,2)共振态和禁域的估计,3)关于共振态的迹公式。

英文摘要:

We consider the 1D massless Dirac operator on the real line with compactly supported potentials. We study resonances as the poles of scattering matrix or equivalently as the zeros of modified Fredholm determinant. We obtain the following properties of the resonances: 1) asymptotics of counting function, 2) estimates on the resonances and the forbidden domain, 3) the trace formula in terms of resonances.
