紧束缚晶格中隧穿非指数衰减与光学Zeno效应

Non-exponential decay via tunneling in tight-binding lattices and the optical Zeno effect

Stefano Longhi

摘要:

本文提出了一个精确可解的耦合到半无限紧束缚晶格的亚稳态衰变模型,在强耦合区,该模型表现出与指数衰变的较大偏差。晶格模型的光学实现,在半无限阵列的隧道耦合光波导的离散衍射的基础上,提出了测试非指数衰减和观察的量子芝诺效应的光学模拟。

英文摘要:

An exactly-solvable model for the decay of a metastable state coupled to a semi-infinite tight-binding lattice, showing large deviations from exponential decay in the strong coupling regime, is presented. An optical realization of the lattice model, based on discrete diffraction in a semi-infinite array of tunneling-coupled optical waveguides, is proposed to test non-exponential decay and for the observation of an optical analog of the quantum Zeno effect.
