Thermodynamics of driven collisionless systems

Felipe B. Rizzato, Renato Pakter, Yan Levin

摘要:

本文提出了一种统计理论,它可以计算一个驱动系统在无碰撞松弛过程后所达到的稳态。应用该理论研究了电子束受外电场驱动的情况。在适当的边界条件下解析求解了Vlasov方程,并与分子动力学模拟进行了比较。一个完美的协议之间的理论和模拟。构造了全电流-电压相图。

英文摘要:

A statistical theory is presented which allows to calculate the stationary state achieved by a driven system after a process of collisionless relaxation. The theory is applied to study an electron beam driven by an external electric field. The Vlasov equation with appropriate boundary conditions is solved analytically and compared with the molecular dynamics simulation. A perfect agreement is found between the theory and the simulations. The full current-voltage phase diagram is constructed.
