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…
Quantum evolution across singularities
Ben Craps, Oleg Evnin
Attempts to consider evolution across space-time singularities often lead to quantum systems with time-dependent Hamiltonians developing an isolated singularity as a function of ti…
D0-brane recoil revisited
Ben Craps, Oleg Evnin, Shin Nakamura
One-loop string scattering amplitudes computed using the standard D0-brane conformal field theory (CFT) suffer from infrared divergences associated with recoil. A systematic framew…
Worldline techniques for string theory solitons: recoil, annihilation and pair production
Oleg Evnin
We analyze a model of interacting particles and strings described by a path integral with the Dirichlet boundary conditions. Such model is a natural framework to examine the proces…
