有限温度下两种含时杂质Luttinger液体的泵浦电流和电导

Pumping current and conductance of a Luttinger liquid in the presence of two time-dependent impurities at finite temperature

Mariano J. Salvay

摘要:

研究了Tomonaga-Luttinger液体中存在两个含时点状弱杂质时的泵浦电流和电导,并考虑了有限温度效应。我们研究了不同的制度,可以建立作为频率,温度和杂质之间的分离潜力的函数。我们展示了以前的零温度或单一杂质的结果是如何扭曲的。

英文摘要:

We study the pumping current and the conductance in a Tomonaga-Luttinger liquid in the presence of two time-dependent point like weak impurities, taking into account finite-temperature effects. We investigate the different regimes which can be established as function of the frequency, the temperature and the separation between the impurity potentials. We show how the previous zero temperature or single impurity results are distorted.
