Yang-Lee edge singularity and quantum criticality in non-Hermitian PXP model
Wen-Yi Zhang, Meng-Yun Mao, Qing-Min Hu +3
We present a comprehensive theoretical framework for quantum criticality in the non-Hermitian detuned PXP model, and establish the complete phase diagram, which had remained elusiv…
Toward Heisenberg Scaling in Non-Hermitian Metrology at the Quantum Regime
Xinglei Yu, Xinzhi Zhao, Liangsheng Li +4
Non-Hermitian quantum metrology, an emerging field at the intersection of quantum estimation and non-Hermitian physics, holds promise for revolutionizing precision measurement. Her…
Experimental investigation of uncertainty relations for non-Hermitian operators
Xinzhi Zhao, Xinglei Yu, Wenting Zhou +4
Uncertainty relations for Hermitian operators have been confirmed through many experiments. However, previous experiments have only tested the special case of non-Hermitian operato…
