Can free strings propagate across plane wave singularities?
Ben Craps, Frederik De Roo, Oleg Evnin
We study free string propagation in families of plane wave geometries developing strong scale-invariant singularities in certain limits. We relate the singular limit of the evoluti…

Notes on quantum evolution across singularities
Oleg Evnin
In a number of model contexts, evolution across space-time singularities (reminiscent of the cosmological singularities) involves time-dependent quantum Hamiltonians developing a s…
