| Plasmons and their interaction with light and energetic electrons |
| Speaker: | Prof. Javier Garcia de Abajo (IO-CSIC, Madrid/Spain) |
| Abstract: | Plasmon excitations at metal surfaces allow us to confine light in nanometer-sized regions. This can be accompanied by a large enhancement of the optical intensity compared to the externally supplied light. These two features (confinement and field enhancement) are triggering a plethora of applications in ultrasensitive detection down to the single-molecule limit, as well as nonlinear optics at the nanoscale. Plasmons can be tailored through size and shape control of metal nanoparticles, and they can also be manipulated in lithographically patterned structures. Several examples of this will be discussed in the seminar, along with a tutorial introduction on how to understand plasmons. The seminar will conclude with recent advances in the study of light-electron interaction, which can be mediated by the evanescent electromagnetic field carried by plasmons.

| Darwin is the Newton of Biology? |
| Speaker: | Evelyn Fox-Keller Massachusetts Institute of Technology, Cambridge, USA |
| Abstract: | Abstract: It has often been claimed that Darwin’s theory of evolution by natural selection put the lie to Kant’s prediction that there will never be “a Newton of a blade of grass”.
I will first argue that, for all Darwin’s achievements, his theory was not able to address Kant’s concerns, and second, re-examine Kant’s predictions in the light of recent developments in biophysics. |
