First measurements of the differential positronium-formation cross-sections

Positrons are the antimatter version of electrons and so their fate in a matter world is ultimately to annihilate. However, prior to this, a positron may combine with an electron to form a matter-antimatter hybrid called positronium. This is akin to a hydrogen atom with the proton replaced by a positron. Fundamental to our understanding of the physical universe, positron and positronium are these days also acknowledged as being fantastically useful in practical applications such as probing material properties and medical diagnostics. However, there is still much that we do not know for sure about the details of the interactions of these particles with ordinary matter. For example if, in a collision with an atom or molecule, a positron captures an electron, in which directions is the positronium likely to travel and with what probability? More...

New calculations to improve carbon dioxide monitoring from space

How light of different colours is absorbed by carbon dioxide (CO2) can now be accurately predicted using new calculations developed by a UCL-led team of scientists. This will help climate scientists studying Earth’s greenhouse gas emissions to better interpret data collected from satellites and ground stations measuring CO2. More...

On quantum scales, there are many second laws of thermodynamics

New research from UCL has uncovered additional second laws of thermodynamics which complement the ordinary second law of thermodynamics, one of the most fundamental laws of nature. These new second laws are generally not noticeable except on very small scales, at which point, they become increasingly important. More...

Open Day for Prospective PhD Students

Atomic Molecular Optical and Positron Physics group will be holding
an Open Day on Thursday December 10th 2015.

The open day will start with Academic Staff talks at 11am in E7/E3 followed by lunch at 12:30pm. Lab talks will begin at 1:30pm. There will be a poster session and finally, guided tours of our labs will be offered. More information TBC 

Come along and find out more about working towards a PhD in our group! You'll get to hear about our research programs, talk to group members and potential supervisor as well as see our labs.

There are PhD opportunities in theoretical and experimental research in the following areas:

  • Cold matter and optical trapping
  • Positron and positronium physics
  • Biological physics: optical and magnetic tweezers
  • Quantum effects in biomolecular systems
  • Quantum information and quantum computation
  • Theoretical molecular atmospheric and astrophysics
  • Ultracold quantum gases
  • Ultrafast laser spectroscopy and strong laser interactions
  • Attosecond, Strong-Field and Free-Electron Laser interactions
