The fact that δ is larger for Na than for Li and largest for Cs reflects that fact that the 3s orbital of Na penetrates ...

Quantum Fields near Black Holes - Theoretisch
... For a black hole the global Killing field is not everywhere timelike. One may exclude the non-timelike region from space time which corresponds to the imposition of boundary conditions. One may also try to retain this region but attempt to define a meaningful vacuum by invoking physical arguments. I ...

Using chain lengths up to L 128, he estimates the gap to be 0.049(18). This result is compared to the findings of o ...
