Lincoln Turner

Lincoln's interests are in the areas of atomic, molecular and optical physics. He is particularly interested in applying ultracold matter and Bose-Einstein condensates to enable precision measurements of magnetic fields, and of the spin properties of novel states of cold matter.

Lincoln is also interested in novel methods of measuring Bose-Einstein condensates with minimal heating of the condensate. He developed a holographic imaging method which reconstructs images of cold atom clouds from diffraction pattern images, and enables high-resolution imaging with minimal heating of the ultracold gas. Recently, Lincoln lead a team at the US National Institute of Standards and Technology (NIST) which demonstrated the first continuous measurement of the spin state of a Bose-Einstein condensate.

Current projects include:

- Ultraprecise magnetometry with optically-trapped Bose-Einstein condensates
- Spontaneous and measurement-induced spin squeezing in spinor BEC (with Yingmei-Liu and Paul Lett, NIST)
- Theory of adiabatic evolution of non-linear spinor systems (with honours student Lucas Rutten)
- Two-colour squeezing from four-wave mixing in hot atomic vapours (collaboration with Martijn Jasperse and Robert Scholten, University of Melbourne)
- High-bandwidth high-quantum efficiency photodetectors for quantum optics (with Paul Lett, NIST)
- Low-light shot-noise limited autobalanced photodetectors
- Simplified designs for narrow linewidth external-cavity diode lasers
