The thorny oyster ( Spondylus gaederopus ), a Mediterranean bivalve prised during prehistoric times for its distinctive spiny purple shell, has since been overlooked in cultural and scientific records. Frequently depicted in Early Modern still-life paintings, particularly in Ital...

On the fate of spacetime singularities
Abstract I investigate spacetime singularities from the point of view of the wavefunction of the universe. In order to extend the classical notion of geodesic incompleteness one has to include the proper time of an observer as a degree of freedom in the Wheeler DeWitt equation. T...

Entropy maximization and weak Gibbsianity of quasi-free fermionic states
Abstract In their 1972 study of approach to equilibrium, Lanford and Robinson showed that gauge-invariant quasi-free states of lattice fermions maximize entropy among all translation-invariant states with a fixed two-point function and suggested that the maximizer is unique. In s...
