On Vacuum Transitions and the String Lanscape

Regular Seminar Senarath de Alwis (University of Colorado)

15:30 IC
room zoom 871 9223 5980

I discuss from a Hamiltonian (Lorentzian) perspective the calculations of vacuum transitions in flat space field theory and in gravitational backgrounds without the use of problematic Euclidean arguments. Some implications for the string theory landscape are highlighted. [please note the unusual time] [please email a.held@imperial.ac.uk for zoom link or password]
