The European Physical Society [EPS], the Centro di Cultura Scientifica Alessandro Volta and Edison S.p.A. are delighted to announce the award of the 2016 EPS Edison Volta Prize for outstanding contributions to physics to

  • Michel Orrit, from the Leiden University, the Netherlands

“for seminal contributions to optical science, to the field of single-molecule spectroscopy and imaging (first single molecule detection by fluorescence and first optical detection of magnetic resonance in single molecule) and for pioneering investigations into the photoblinking and photobleaching behaviours of individual molecules at the heart of many current optical super-resolution experiments.”

Professor Orrit has made significant contributions over several decades to push back the frontiers of optical physics and spectroscopy. More than 30 years ago, he produced very early and highly insightful work on Langmuir-Blodgett films and spectral hole-burning in the 1980’s. After work in my lab in 1989 to detect the optical absorption of a single molecule of pentacene in p-terphenyl, in Bordeaux he demonstrated one year later that the optical absorption could be detected with greatly improved signal-to-noise by detecting the fluorescence emitted from the single molecule. This critical and ground-breaking step opened the way for many subsequent investigations of single molecules throughout the 1990’s up to the present. Indeed, essentially every group in the world has subsequently used fluorescence excitation as a result of this seminal work.

In a series of very impressive experiments, Orrit systematically explored many facets the behaviour and local dynamics of single aromatic hydrocarbons in molecular crystals at low temperatures. Major accomplishments in the 1990s included study of Stark effects in polymers, the beautiful demonstration of two-level system dynamics by autocorrelation of frequency fluctuations, temperature dependence of spectral diffusion in polymers, and optical detection of magnetic resonance and coherence effects for a single molecular spin. In the mid-1990’s, Professor Orrit began to focus on various quantum optical effects that may be observed with a single molecule in a solid. After the first observation of photon antibunching for a single molecule in collaboration with the IBM group, Professor Orrit pushed forward to demonstrate ac Stark effects, hyper-Raman effects, Rabi resonances, and a triggered single photon source using adiabatic rapid passage. All of these experiments in his lab in France were “firsts”, and placed Prof. Orrit’s group at the position of the premier group worldwide exploring quantum optical effects with single molecules in solids.

Throughout his subsequent career up to the present, Prof. Orrit has shown an incredible ability to select and conquer some of the most interesting problems in modern molecular physics and spectroscopy. He has extended his efforts to study glass dynamics over a wide range of temperatures, has provided deep insight to the optical properties of metallic nanoparticles, and has even detected the optical absorption of single molecules at room temperature using photothermal effects. His deep and leading-edge research has yielded an array of new methods, new physical effects, and he has trained a number of talented young laser scientists.

When contacted, Professor Orrit expressed his thanks to the committee. He works at the Biological and Molecular Physics at the Leiden Institute of Physics. He has been at Leiden University since 2001.

EPS Edison-Volta Prize

The EPS Edison Volta Prize promotes excellence in research and is given in recognition of outstanding research and achievements in physics. The EPS Edison Volta Prize is given biennially to individuals or groups of up to three people. The laureates receive a medal, which is a faithful reproduction of the “Medaglia Premio dell’ Associa-zione per l’Incremento del Commercio in Como”: a portrait of Alessandro Volta together with the saying: Alexandro Voltae Novocomensi, i.e. (dedicated) to Alessandro Volta from Novum Comum, which was the old name given to the city of Como by Julius Caesar.

The Prize was established in 2011 and was awarded for the first time in 2012 to R. D. Heuer, S. Bertolucci and S. Myers and to J.-M. Raimond in 2014. It was also given to members of the ESA Max Planck Mission in 2015 in the frame of the International Year of Light 2015.
