PhD supervision

Please contact me if you are interested in PhD in low temperature physics. PhD projects are available on: experimental observations and computer simulations of quantum turbulence probing of superfluid 3He and 4He using conventional and nano-electromechanical oscillators, cooling nano-electromechanical objects to low temperature.

Research Interests

As a low temperature physicist, I investigate properties of matter in the vicinity of absolute zero. By cooling material down, the thermal motion of atoms and electrons is arrested, revealing the subtle nature of quantum mechanics and associated effects which are hidden at room temperature. Matter at low temperatures allows us to model and to understand complex and sometimes unsolvable physical problems ranging from classical systems to cosmology. Throughout my career I was using quantum systems as a route to the classical world. 

My current research directions include investigating pure quantum turbulence in superfluids, building and cooling detectors based on micro and nano-electromechanical systems, developing a compact refrigerator for quantum computing platforms, and looking for dark matter using properties of superfluid He3.   

Career Details

I am an alumnus of Tartu University in Estonia, where during my master degree I studied scillators at liquid helium temperatures. My interest in low temperatures has exploded during my doctorate degree at the Low Temperature Laboratory at Helsinki University of Technology where I measured morphology and growth kinetics of helium-3 crystals below 1 mK using optical interferometry. After doctorate degree I have spent three years at the Stanford University in a group of Doug Osheroff researching magnetization of superfluid Helium-3 in the vicinity of superfluid transition. I started to work at Lancaster Ultra Low Temperature Group as a postdoc in 2004 and received an EPSRC Advanced Research Fellowship in 2006. In 2008 I was awarded the International Union of Pure and Applied Physics Young Scientist Prize for my contribution to the fields of quantum crystals and quantum turbulence. Presently I am Head of Lancaster Ultra Low Temperature Group.
