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.

Macroscopic and microscopic work.

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...

Dr. Stephen Hogan

Welcome to the website of the group of Dr. Stephen Hogan. Our research is centred around the study of atoms and molecules in highly excited Rydberg states. In particular we are interested in exploiting samples in these states for:

  1. Applications in quantum information processing
  2. Studies of cold molecules
  3. Experiments with antihydrogen.

If you are interested in joining the group as a postdoctoral researcher or for a PhD, MSc or MSci/BSc project please contact Stephen Hogan for further information.
