High-Pressure Neutron Scattering Studies of High-Tc Superconductors

Central to the current debate on the mechanism underlying high-temperature superconductivity is the question of whether electron pairing in cuprates is caused by the exchange of bosonic excitations and can therefore be described by an extension of the Bardeen-Cooper-Schrieffer (BCS) theory, which has successfully explained phonon-mediated superconductivity in metals and alloys for the past 50 years.



Neutron Diffraction Studies on Magnetoelectric Multiferroics

Magnetism and ferroelectricity are essential to many forms of current technology. The multiferroic-based device could provide an efficient link between conventional electronic logic and spin-based logic, which offers the potential for significantly reduced energy consumption compared to present-day integrated circuits. An important number of magnetoelectric multiferroics has the general chemical formula ABO3 and crystallizes in a perovskite or perovskite-related structure.



Electron-correlated Systems under Pressure

Emergence involving correlations between d and f electrons in materials
(namely eletctron strongly correlated  materials) induces a staggering 
variety of novel phenomena, such as, ferromagnetism, antiferromagnetism,
unconventional and high-temperature superconductivity, charge- and
orbital-density waves, electronic phase separation, stripes,
ferroelectricity, colossal magneto-resistance and magneto-capacitance.
