众所周知,当不稳定量子系统被频繁测量时,量子Zeno效应就会发生,此效应在量子信息和量子通信中具有重要意义.然而,以前人们所研究......

The Zeno time has been calculated for a metastable two-level atom tunneling through a interacting thermal magnetic field......

Our main aim is to prove a more general version of the quantum Zeno effect. Then we discuss some examples of the quantum......

Guiding of waves between parallel absorbing walls is considered. The principal mode is constructed;its absorption is est......
