Unification of quantum Zeno-anti Zeno effects and parity-time symmetry breaking transitions
Jiaming Li, Tishuo Wang, Le Luo +2
The decay of any unstable quantum state can be inhibited or enhanced by carefully tailored measurements, known as the quantum Zeno effect (QZE) or anti-Zeno effect (QAZE). To date,…

Observation of two PT transitions in an electric circuit with balanced gain and loss
Tishuo Wang, Jianxiong Fang, Zhongyi Xie +5
We investigate PT -symmetry breaking transitions in a dimer comprising two LC oscillators, one with loss and the second with gain. The electric energy of this four-mode model oscil…
