利用电场调制控制Tomonaga-Luttinger指数

Manipulating the Tomonaga-Luttinger exponent by electric field modulation

Hiroyuki Shima, Shota Ono, Hideo Yoshioka

摘要:

我们建立了人工控制Tomonaga-Luttinger液态幂律奇异性的理论框架。幂律行为的指数被发现显着增加的周期性电场调制施加到系统的振幅的增加。这种场诱导的指数移动表明准一维电子系统的输运性质的可调谐性。

英文摘要:

We establish a theoretical framework for artificial control of the power-law singularities in Tomonaga-Luttinger liquid states. The exponent governing the power-law behaviors is found to increase significantly with an increase in the amplitude of the periodic electric field modulation applied externally to the system. This field-induced shift in the exponent indicates the tunability of the transport properties of quasi-one-dimensional electron systems.
