Holographic phenomenology via overlapping degrees of freedom
Oliver Friedrich, ChunJun Cao, Sean M. Carroll +2
The holographic principle suggests that regions of space contain fewer physical degrees of freedom than would be implied by conventional quantum field theory. Meanwhile, in Hilbert…
How Low Can Vacuum Energy Go When Your Fields Are Finite-Dimensional?
ChunJun Cao, Aidan Chatwin-Davies, Ashmeet Singh
According to the holographic bound, there is only a finite density of degrees of freedom in space when gravity is taken into account. Conventional quantum field theory does not con…
The Hilbert Space of Quantum Gravity Is Locally Finite-Dimensional
Ning Bao, Sean M. Carroll, Ashmeet Singh
We argue in a model-independent way that the Hilbert space of quantum gravity is locally finite-dimensional. In other words, the density operator describing the state corresponding…
