| Title: | The cosmological constant, unimodular gravity, and nonlinear quantum mechanics |
| Date (JST): | Wed, Jan 14, 2026, 13:30 - 15:00 |
| Place: | Seminar Room A |
| Abstract: |
I will present the cosmological constant problem from the Hamiltonian perspective, and review unimodular gravity from the same perspective. I will discuss what it might take to solve the cosmological constant problem in this context, and show that non-linear mechanics is an option. I will also briefly discuss how weakly we have tested the Einstein-Hilbert action as the basis of quantum gravity. |
