Cover Story: The hermiticity of closed quantum systems is a fundamental principle; however, a real physical system cannot be completely isolated from the environment. Generally, the Lamb shift describes this gap by quantifying the difference between energy eigenvalues. However, a certain appearance of Lamb shift and collective Lamb shift between two subsystems is very weak when the openness effects are involved. Accordingly, we need to consider a different disparity, not of eigenvalues but eigenfunctions. Here, we have exploited the relative entropy to quantify the gap and found that the average value of relative entropy in the collective Lamb shift is large, while that in self-energy is small. Furthermore, weak and strong interactions in the non-Hermitian system display an obvious exchange of eigenfunctions. View this paper

Projects are rarely executed exactly as planned. Often, the actual duration of a project’s activities differ from the planned duration, resulting in costs stemming from the inaccurate estimation of the activity’s completion date. While mo...

Machines usually employ a guess-and-check strategy to analyze data: they take the data, make a guess, check the answer, adjust it with regard to the correct one if necessary, and try again on a new data set. An active learning environment guarantees...

Based on conditional past–future (CPF) correlations, we study the non-Markovianity of a central spin coupled to an isotropic Lipkin–Meshkov–Glick (LMG) bath. Although the dynamics of a system is always non-Markovian, it is found tha...
