Axions and axion-like particles (ALPs) are a prominent dark matter candidate, drawing motivation in part from the axiverse of string theory. However, the string axiverse is not the only game in town: In this talk I will discuss axion-like particles that emerge as pions of a QCD-like dark sector. In a dark Standard Model (SM) wherein all 6 quark flavours are light while the photon is massive —...
The Penrose inequality places a lower bound on the mass of a black hole spacetime in terms of the area of a cross-section of the event horizon. The heuristic argument for the inequality is based upon the standard picture of gravitational collapse and it has been rigorously proved in the setting of time-symmetric initial data. We will discuss the derivation of a Penrose-type inequality with...
Using an exact solution for a two-dimensional scalar field propagating in a variation of the Alcubierre metric, we analyze how apparent horizons affect localized quantized wavepackets. We analyze the loss of fringe visibility in a single-photon interferometer, and the reduction of entanglement between two 2D photons, if one photon travels through a region with spacetime curvature. We also...
The direct observation of gravitational waves was one of the most exciting events in physics in the last decade. It opened a whole new window for studying the universe and prompted a lot of interest in the observable effects of gravitational waves. One example of this is studying the effect of gravitational waves on quantum fields. In this talk I will discuss the series solution of the...
The Lambert W function has been used in solving a variety of diverse problems in a variety of topics in physics, chemistry, engineering and mathematics. In physics, it has been useful in the study of statistical distributions such as the Planck black body, Fermi-Dirac and Bose-Einstein distributions and the fringe fields associated with a parallel plate capacitor, the study of thermoelectric...
