Research

Low Temperature Quantum Physics Group performs the experimental researches in condensed matter physics at very low temperatures, in high magnetic fields and under high pressures. Besides the developments of new techniques and detection systems under such extreme conditions, synthesis of novel materials and growth of high quality single crystals are other major activities of the group. The following topics are currently under investigation.

  • Quantum spin system realized in rare-earth-based compounds.
  • Spin texture on Fermi surface in non-centrosymmetric metals revealed by the de Haas-van Alphen effect.
  • Novel magnetic and electronic properties in the vicinity of a quantum critical point.

The group is also responsible for the operation of Center for Low Temperature Science which supports versatile researches at low temperatures in Tohoku University.
