Calendar of Physics Talks Vienna
| Ghosts without runaway instabilities |
| Speaker: | Cedric Deffayet (IHES Paris) |
| Abstract: | I will discuss simple mechanical models with a ghost (i.e. a mode with a negative kinetic energy) interacting with a positive energy degree of freedom, and yet, the phase-space motion can be shown analytically and numerically to be fully stable thanks to integrability. Extensions to field theories will also be discussed. |
