Innovation at the cold frontier for current and future quantum devices and sensors

The Low Temperature Physics Laboratory at Lancaster University, a founder member of the European Microkelvin Platform, designs and constructs record-breaking millikelvin dilution refrigerators and sub-millikelvin adiabatic demagnetisation stages, building on the expertise, infrastructure and technical capabilities that have been developed and refined over many years. Research runs from blue-skies work in superfluid helium-3 and helium-4 at temperatures close to absolute zero, through to innovation and technology transfer of refrigeration, instrumentation and ultra-sensitive measurement techniques to academic and commercial collaborators. This talk will describe some of our recent research highlights including: the discovery of super-critical superfluid condensate flow; exploiting high quality factor nanomechanical resonators as force sensors over many orders of magnitude; and developing new techniques for delivering microkelvin electron temperatures in nano-fabricated on-chip devices.
