报告题目:Berry’s phase and Surface Plasmon Polaritons

报 告 人:Prof. Taco Dirk Visser

Delft University of Technology and Vrije Universiteit




We normally think of the phase of a system as something that depends only on time: the dynamic phase. However, there is also another phase that depends on how a system has traveled: the geometric phase. The most famous example of such a geometric phase is Berry’s phase that occurs in quantum systems. In general a system’s total phase will be the sum of a dynamic phase plus a geometric phase. In this talk I will present several examples of geometric phases and discuss their physical meaning. Surface plasmon polaritons (SPPs) are electromagnetic surface waves that propagate along the interface of a metal and a dielectric medium. They play an ever-growing role in nano-optics. In so-called plasmonic structures, light is converted into SPPs which are turned back into light again. In order to apply SPPs, it is important to understand their phase behavior. We have therefore examined whether geometric phases play a role in plasmonics. I will discuss a recent experiment in which it was demonstrated that a) SPs can carry a geometric Pancharatnam-Berry phase, and b) that this phase survives the light → SP → light process.

Personal details

Education:PhD in Theoretical Physics, University of Amsterdam, 1992


Current position

Full Professor at Delft University of Technology and Vrije Universiteit Amsterdam. I have taught many course over the years, ranging from Optics, and Relativitstic Electrodynamics to Quantum Optics. I currently supervise three PhD students. Two of which are halfway, the third is practically finished. Eventually they will defend their thesis in Amsterdam. As a Long Term Visiting Professor at both the University of Rochester (USA), and Northwestern Polytechnical University in Xi’an (China) I collaborate intensively with scientists there. I have been a Visiting Professor at Aalto University (Finland), and I have just been invited to become Visiting Professor at ETH Zurich (Switzerland).


My research is mostly in Theoretical Optics with an emphasis on coherence theory, nano-optics and plasmonics. This happens in collaboration with ETH (Switzerland), NASA (Cleveland), UNC Charlotte (USA), AMOLF (Amsterdam), University of Eastern Finland, University of Rochester, and NPU (China). Since several years I also initiate experiments which are presently carried out with groups in Amsterdam (Prof. W. Ubachs), Finland (Prof. A.T. Friberg) and ETH Zurich (Prof. L. Novotny). My work has led to several publications in, for example, Physical Review Letters.

My h-index is 35 (Google Scholar), with more than 3800 citations.

All my publications (more than 100) can be downloaded from my home pagewww.nat.vu.nl/~tvisser
