The Centre of Excellence in Low Temperature Quantum Phenomena and Devices LTQ

Nano cryostat

Research at LTQ

At low temperatures near absolute zero, physical systems eventually condense into their quantum mechanical ground state, and may exhibit extraordinary properties. In the superconducting state of metals, the electric current flows without loss, and in the superfluid state of helium, the flow is lossless as well. Both of these are macroscopic quantum-mechanical phenomena. The applications of the research include superconducting sensors for terahertz imaging and calorimeters and thermometers for low temperature research.

During 2012-2017 LTQ implemented an ambitious research program, focusing on investigations of quantum phenomena, both in extremely ideal continuous media, such as helium liquids and crystals, and in man-made nano structures. The program received support from the Academy of Finland, EU, universities, research institutes, the private business sector and many other sources. During its operation, the centre graduated nearly 40 Doctors and 30 Masters and its teams published more than 400 peer reviewed scientific papers. The research led to roughly 30 public patents and 3 spin-offs during the six years of operation.

Groups

LTQ was formed around eleven leading research groups of its field from Aalto University, VTT Technical Research Centre of Finland and University of Jyväskylä:

Scientific Advisory Board (SAB)

LTQ had a scientific advisory board which reviewed the scientific progress of the centre, and provided valuable support for its' development:

Prof. William Halperin, Northwestern University, Evanston, Illinois, USA

Prof. Andrew Cleland, University of Chicago, USA

Prof. Milena Grifoni, Universität Regensburg, Germany 7.10.2014 -->
