一维瑞利气体中示踪粒子扩散的零质量极限

On the zero mass limit of tagged particle diffusion in the 1-d Rayleigh-gas

Peter Balint, Balint Toth, Peter Toth

摘要:

我们考虑一维瑞利气体中标记粒子扩散的M -> 0极限,这一极限最初由Sinai和Soloveichik(1986)以及Szasz和Toth(1986)分别研究。在此极限下,我们导出了一种新的标记粒子扩散模型,两个中心粒子之间具有Calogero-Moser-Sutherland(即反二次)相互作用势。对这个新模型的计算机模拟精确地再现了Boldrighini,Frigio和Tognetti(2002)获得的极限方差的数值。

英文摘要:

We consider the M -> 0 limit for tagged particle diffusion in a 1-dimensional Rayleigh-gas, studied originaly by Sinai and Soloveichik (1986), respectively by Szasz and Toth (1986). In this limit we derive a new type of model for tagged paricle diffusion, with Calogero-Moser-Sutherland (i.e. inverse quadratic) interaction potential between the two central particles. Computer simulations on this new model reproduce exactly the numerical value of the limiting variance obtained by Boldrighini, Frigio and Tognetti (2002).
