Is the Coleman de Luccia action minimum?: AdS/CFT approach
Naritaka Oshita, Yutaro Shoji, Masahide Yamaguchi
We use the anti-de Sitter/conformal field theory (AdS/CFT) correspondence to find the least bounce action in an AdS false vacuum state, i.e., the most probable decay process of the…

Path Integral for Mixed Tunneling, Polychronic Tunneling and Quantum Gravity
Yutaro Shoji
Quantum tunneling in a many-body system is much more non-trivial than that in a one-body system. The most characteristic phenomenon is the mixed tunneling, which has been studied i…

Polychronic Tunneling: New Tunneling Processes Experiencing Euclidean and Lorentzian Evolution Simultaneously
Naritaka Oshita, Yutaro Shoji, Masahide Yamaguchi
We discuss new possible tunneling processes in the presence of gravity. We formulate quantum tunneling using the Wheeler-deWitt canonical quantization and the WKB approximation. Th…
