具有非标准动力学项的预热

Preheating with Non-Standard Kinetic Term

Jean Lachapelle, Robert H. Brandenberger

摘要:

我们考虑在理论中的非标准动力学项的通货膨胀后的再加热。我们表明,具有参数共振的方程是希尔-惠特克方程,这是一个特殊的情况下,更一般的希尔方程。该方程通常比Mathieu方程更不稳定,使得窄共振预热在具有非正则动力学项的理论中可能是有效的。

英文摘要:

We consider reheating after inflation in theories with a non-standard kinetic term. We show that the equation that exhibits parametric resonance is the Hill-Whittaker equation, which is a particular case of the more general Hill equation. This equation is in general more unstable than the Mathieu equation, such that narrow resonance preheating may be efficient in theories with a non-canonical kinetic term.
