定能一维单组分库仑气体的精确解

Exact solution to the 1d one component Coulomb gas at fixed energy

Timothy D. Andersen

摘要:

一维单组分等离子体可应用于具有对数相互作用的一维粒子系统,如单通道导线中的电荷或流体对流中的涡丝。我们已经计算了这种等离子体在具有高斯约束势的正则系综中的精确积分。在本文中,我计算的精确体积的等离子体的N粒子在固定的能量没有限制的潜力,使用微正则系综和显示,在二维的情况下,它具有负温度状态,这表明,一维湍流可以发生从涡旋/电子集群。

英文摘要:

The one dimensional one component plasma has applications to one dimensional particle systems with logarithmic interactions such as charges in a single channel wire or vortex filaments in a fluid convection stream. The exact integral of this plasma in the canonical ensemble with a gaussian confining potential has already been computed. In this paper, I compute the exact volume of the phase space of the plasma of N particles at fixed energy without a confining potential using a microcanonical ensemble and show that, as in the two-dimensional case, it has negative temperature states, suggesting that one dimensional turbulence can occur from vortex/electron clustering.
