Theory ColloquiumA Quantum-Mechanical Mechanism for Reducing the Cosmological Constant
Nemanja Kaloper (UC Davis)
We exhibit a mechanism which dynamically adjusts cosmological constant toward 0+. The adjustment is quantum-mechanical, discharging cosmological constant in random discrete steps. It renders de Sitter space unstable, and triggers its decay toward Minkowski. Since the instability dynamically stops at Λ=0, the evolution favors the terminal Minkowski space without a need for anthropics. The mechanism works for any QFT coupled to gravity.
