ABOUT US

Welcome to Junko Taniguchi's web page. We are experimentally studying quantum effects in low-dimensional systems of quantum fluids and solids. Especially, we are interested in superfluidity specific to one-dimensional systems. We are also exploring the sliding friction of physisorbed films at low temperatures.

Research Interests

Quantum Fluids and Solids

  • Superfluid response of 4He confined to one-dimensional(1D) nanochannel structures
  • Developments of new nano-Helmholts resonator combined with 1D nanochannels
  • Pressure-induced qunautm critical phenomena of 4 in 1D nanochannels

Nanotribology

  • Friction of noble gas physisorbed films on various substrates
  • Influence of superfluid overlayer onto the sliding friction of underlayer solid

Recent Research Highlights

Temperature-dependent decoupling and sticking of 4He films

Superfluid response of 4He confined in 2.8-nm channels
