强监控下量子链中的输运

Transport in quantum chains under strong monitoring

D. Bernard, T. Jin, O. Shpielberg

摘要:

研究了强监控下一维量子系统的输运性质。量子芝诺效应抑制传输并诱导局域化。在芝诺冻结和长时间尺度上,一种新的动力学以马尔可夫过程的形式出现。在强监控下研究费米子链和玻色子链,我们能够确定经典排斥过程、包含过程和厌世过程的一个子类的量子起源。此外,我们表明,被动监测不能打破时间反演对称性和运输一般失去其弹道性质存在弱测量。

英文摘要:

We study the transport properties of quantum 1D systems under strong monitoring. The quantum Zeno effect inhibits transport and induces localization. Beyond the Zeno freezing and on long time scales, a new dynamics emerges in the form of a Markov process. Studying fermionic and bosonic chains under strong monitoring, we are able to identify the quantum origin of the classical exclusion process, inclusion process and a sub-class of the misanthrope process. Moreover, we show that passive monitoring cannot break time-reversal symmetry and that the transport generally loses its ballistic nature existing for weak measurements.
