    • Abstract:In this talk, we present a couple of recent results touching on some theoretical aspects of gravitational waves. For the first component of the seminar, we explain various details of a procedure to compute one-loop corrections to the primordial scalar and tensor spectra using both dimensional and cutoff regularization, refining a seminal result due to Weinberg. The second part of the talk concerns the tidal deformability of black holes. We review the notion of tidal Love number, and show that the TLN of a black hole in Randall-Sundrum theory can be non-vanishing, as opposed to the Schwarzschild solution in ordinary GR. This serves as an example of how TLN could be a potential indicator of new physics in gravitational waveforms.
