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
