introduction
- quantum jitters or quantum fluctuation
vacuum energy
- ground state energy
- vacuum state energy
- zero point energy
QFT and the vacuum amplitude
- 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.
Vacuum energy density
- We can measure the Vacuum energy density by cosmological microwave background.
- a non-zero vacuum energy is expected to contribute to the cosmological constant, which affects the expansion of the universe.
- Casimir effect
- central charge
