Abstract :

Artificially-structured oxide superlattice is a fascinating playground for the new material functionality originated from strong electronic �Correlation�. When the conventional bulk material becomes 2D-like, the intriguing �Correlated Phenomena� can emerge as a result of cooperation between the spin, orbital and lattice degree of freedom. As one typical example, we present our calculation results on the nickelate superlattice, LaNiO3/LaAlO3. Based on the first-principles density functional theory calculation combined with the state-of-the-art �Many-body� techniques, we examined the possibility of unconventional superconductivity and emerging magnetic order in the thin LaNiO3-limit. The dynamic as well as static �Correlation Effect� has been analyzed and the results are compared with recent experimental reports.
