Quantum mechanics explains efficiency of photosynthesis

Light-gathering macromolecules in plant cells transfer energy by taking advantage of molecular vibrations whose physical descriptions have no equivalents in classical physics, according to the first unambiguous theoretical evidence of quantum effects in photosynthesis published today in the journal Nature Communications.

Quantum engines must break down


Our present understanding of thermodynamics is fundamentally incorrect if applied to small systems and needs to be modified, according to new research from University College London (UCL) and the University of Gdańsk. The work establishes new laws in the rapidly emerging field of quantum thermodynamics. More...

Professor Ferruccio Renzoni joined the Faculty of University College London in October 2003. Since then, he has led the Laser Cooling Group in the Department of Physics.

Biography

Ferruccio Renzoni studied Physics at the University of Pisa (Italy) where he obtained his M.Sc. in 1993. He obtained his Ph.D. from the Technische Universitaet Graz (Austria) in 1998 with a thesis on dark states and coherent population trapping in atomic systems. He then spent two years in Germany, at the Institut fuer Laserphysik of the University of Hamburg, and three years in France, at the Laboratoire Kastler Brossel (Ecole Normale Superieure, Paris), where he obtained his "Habilitation a diriger des recherches". Since 2003 he has been at the Department of Physics and Astronomy of the University College London, where he leads the laser cooling group.

Research Interests

Ferruccio's research interests include different topics in quantum optics and cold-atom physics. Current research projects are:

Cavity cooling of cesium atoms

The confinement of atoms in optical resonator leads, for an appropriate choice of parameters, to new cooling mechanisms. These are of interest as they are applicable also to molecules.

The aim is to study experimentally cooling mechanisms in leaky cavities. Cesium atoms are used for this purpose.

AC driven ratchets for cold atoms

The aim is to control the motion of atoms in a driven optical lattice. By applying a zero-mean oscillating driving force, it is possible to control the atomic motion within the optical lattice by varying the time-symmetry of the driving.

Quantum control via dark states

Atomic evolution via adiabatic following of a dark state allows to prepare and manipulate, in a precise and robust way, the quantum state of an atom. The aim is to demonstrate, via adiabatic following of dark states, the complete control of a quantum state of non-interacting dipole trapped atoms. This will then be extended to interacting atoms, with important applications in quantum information.
