摘要:

利用局域量子费舍尔信息和单向量子亏损,研究了自旋为1/2的$XX$链在三自旋相互作用下的量子相变,并证明了量子涨落.分析结果的推导和详细分析。

英文摘要:

We explore quantum phase transitions in the spin-1/2 $XX$ chain with three-spin interaction in terms of local quantum Fisher information and one-way quantum deficit, together with the demonstration of quantum fluctuations. Analytical results are derived and analyzed in detail.
