I am looking for papers which seek out to justify that the cosmological "constant" could be time-dependent. I am aware that within the framework of GR the cosmological constants really has to be a constant. But outside the framework of GR are there any physical arguments that speak for dark energy to be dynamic? I have been looking for papers but I can't find anything reasonable.

  • $\begingroup$ "Outside of GR", what does "cosmological constant" even mean? $\endgroup$ – ACuriousMind Jul 7 at 15:27
  • $\begingroup$ Well, I am thinkin that a quantum gravity theory would have to explain dark energy as well and in that framework dark energy might be dynamic. $\endgroup$ – eeqesri Jul 7 at 15:38

    $\begingroup$ The broader term including “running cosmological constant” is “dark energy”. Consequently, googling for dark energy should produce the papers you are looking for, like this one: arxiv.org/abs/1103.5870 . $\endgroup$ – A.V.S. Jul 7 at 15:56
