Several new exciting phenomena have been recently discovered in the domain of quantum liquids confined in nanoporous media and on nanotube surfaces. For example , it was shown that liquid He-4 in porous media no longer supports classic phonon-roton modes when the pressure is increased above 35 bars. This is also an example of a quantum phase transition (superfluid - normal He-4) at T ≈ 0. Another surprising finding concerns new quantum systems, like 1D and 2D solid helium that stabilizes on nanotube surfaces. These systems have been investigated using neutron scattering methods, numerical simulation and analytical modelling. These studies involve close collaboration between experimentalists, theoreticians and the Computing for Science group.

After more than 25 years of intensive research, recent experiments have revealed new interesting phenomena in the high-temperature superconducting materials connecting the hight-temperature superconducting mechanism to the strongly-correlated many-particle physics of the Mott transiton. The so-called hot\cold spots on the Fermi surface of high-temperature superconductors, observed for example in Angle Resolved Photoemission Spectroscopy, have been recently found by M. Civelli et al. [PRL 2005, PRB 2006] by numerical non-perturbative studies (Cellular Dynamic Mean Field Theory) of anomalous superconductivity in doped Mott insulators. The result also accounts for the observed asymmetry in angle-resolved photoemission experiments of electron/hole doped systems.
