The Lancaster Low Temperature group performs experiments on superfluids and other materials with wider applications in areas such as nanoelectronics, cosmology and turbulence.
The group has a strong international reputation for performing state-of-the-art experiments at the lowest achievable temperatures. Our custom made dilution refrigerators, built in-house, achieve world-record low temperatures. We have pioneered several innovative approaches including: 'Lancaster-style' demagnetisation stages to cool superfluid helium-3 to record low temperatures; 'heat-flush' procedures to produce highly purified helium-4; ion transport measurement methods for quantum fluids; novel NMR systems; and various mechanical oscillator techniques which provide extremely sensitive thermometry and bolometry at microkelvin temperatures.
We are well known for providing these sub-millikelvin low temperature environments with advanced in-house cryogenic engineering, and for our accompanying expertise in ultra-sensitive measurement techniques and the development of specialised instrumentation.
Creating, controlling and exploiting the ultra-low temperature environment has proven crucial for the research and development of quantum-enhanced devices. Our platform technology provides the extreme cold and isolation necessary to probe the subtle quantum behaviours that are otherwise hidden by thermal fluctuations or external disturbance.
We have a broad research portfolio in low temperature physics and specialise in quantum fluids and solids research. We have performed ground-breaking research on numerous topics, including
- superfluid analogues of cosmological processes
- ion and vortex ring dynamics
- ballistic quasiparticle beams
- exotic superfluid spin phenomena
- superfluid phase nucleation
- phase boundary dynamics
- wave turbulence
- quantum turbulence
- Cooling and sensitive measurement techniques
- Quantum fluids and solids
- Superfluid 3He

- Properties of materials at ultra-low temperatures
- MEMS and NEMS devices at low temperatures
- Extremely cold devices and associated quantum technologies
- Development of sensitive measurement techniques
