题目：Schwarzian Theory and Cosmological Constant

摘要：

The cosmological constant’s quantum origin is a famous open problem in theoretical physics and cosmology. Its observed value and theoretical prediction exhibit a large 120-order discrepancy. In this talk, we first summarize the current state of research on the cosmological constant problem and review the results of Schwarzian theory in the literature. Inspired by an early work by Gary Gibbons, we apply Schwarzian theory and its ensemble average to the cosmological constant problem and propose a new approach to resolving it. We will show that this new method yields a theoretical value that is surprisingly close to the observed value. This talk is based on an upcoming paper.
