Abstract

We investigate the anti-Zeno phenomenon as well as the quantum Zeno effect for the irreversible quantum tunneling from a quantum dot to a ring array of quantum dots. By modeling the total system with the Anderson-Fano-Lee model, it is found that the transition from the quantum Zeno to the quantum anti-Zeno effect can happen by adjusting magnetic flux and gate voltage.
