"Vacuum energy and Casimir effect"의 두 판 사이의 차이

In QFT, there is a way to relate the vacuum energy density with the vacuum amplitutde.
QFT provides ways to compute the vacuum amplitude.
Sometimes it is related to the zeta values.

a non-zero vacuum energy is expected to contribute to the cosmological constant, which affects the expansion of the universe.
