In the last few decades, statistical analysis of cosmic microwave background (CMB) temperature fluctuations has established the standard model of cosmology with high precision. The next frontier lies in…
Interference is one of the most universal phenomena in nature, as exemplified by the real-time Feynman path integral. Despite the ubiquity of interference patterns, their evaluation has often proven challenging.…
I discuss work in progress on obtaining a reasonable density matrix of the universe in two dimensional quantum cosmology. I will do so by comparing aspects of the Hilbert space of closed universes in JT gravity…
