Talks by Stephon Alexander
The Hartle-Hawking-Vilenkin state is defined on mini-superspace and is semiclassically related to inflationary theory. However, the state suffers a few problems connected to the path integral of Euclidean or the Lorentzian measure of metrics. In this talk, we will explore a way around these issues by working in the (Ashtekar) connection representation, a real Kodama-Chern-Simons state. We find a generalized "Fourier Transform" that related the Chern-Simons-Kodama state to the Hartle-Hawking state beyond mini-superspace. We end with some discussion and open ended questions for cosmology
Non-thermal quantum black holes
If we take the idea of the Planck length as a fundamental (minimum) scale and if additionally we impose the Cosmological Constant ($Lambda$) as and infrared (IR) cut-off parameter. Then it is possible to demonstrate that Dark Matter effects can emerge as a consequence of an IR-UV mix effect. This opens the possibility of unifying the Dark Energy and Dark matter effects in a single approach.
