Notes on Quantum Effective Actions
S. P. de Alwis
We first note that, at least in perturbation theory, there is a well-defined (subject to regularization) Lorentzian definition of the quantum effective action in both flat and curv…
Radiative Generation of dS from AdS
S. P. de Alwis
The large volume scenario (LVS) of type IIB string compactifications has a robust supersymmetry breaking minimum with a negative cosmological constant (CC). We argue that radiative…
Wilsonian Effective Field Theory and String Theory
S. P. de Alwis
We argue that deriving an effective field theory from string theory requires a Wilsonian perspective with a physical cutoff. Employing proper time regularization we demonstrate the…
Higher Derivative Corrections to Lower Order RG Flow Equations
S. P. de Alwis
We show that the RG flow equation for the cosmological constant (CC) receives contributions (in addition to those coming from the CC the Einstein-Hilbert term and and $R_{μ…
De Sitter vs Quintessence in String Theory
Michele Cicoli, Senarath de Alwis, Anshuman Maharana +2
De Sitter solutions have been recently conjectured to be incompatible with quantum gravity. In this paper we critically assess the progress and challenges of different mechanisms t…
One PI and Wilsonian Actions in SUSY theories
S. P. de Alwis
The soft breaking terms in supersymmetric theories are calculated at some high scale characterizing the hidden supersymmetry breaking sector, and then evolved down to the TeV scale…
