Our research interests are:
● superfluidity and superconductivity,
● magnetic frustration,
● strong correlation effects in fermion systems,
● quantum Hall effects,
mainly in two dimensional (2D) quantum many-body systems where fluctuation effects are important.
Actual materials we are studying are:
○ 2D fluid and solid helium,
○ graphene,
○ anisotropic or ultra-thin superconductors,
○ 2D electron systems in semiconductors.
Although they are widely spread, we are trying to extract new and general concepts in physics behind them.
With a variety of experimental techniques such as
● specific heat measurement,
● cw- and pulsed-NMR (nuclear magnetic resonance),
● STM (scanning tunneling microscopy) and
● STS (scanning tunneling spectroscopy),
● AFM (atomic force microscopy),
● electronic transportation,
we are carrying out our experiments in a wide temperature range down to 60 micro-K.
