Local Electronic Structure of PbVO3, a New Member of PbTiO3 Family, studied by XANES/ELNES

Sher Alam, Alexei A. Belik, Y. Matsui

Recently an interesting multi-ferroic system PbVO3 [Chem. Mater. 2004] was successfully prepared using a high-pressure and high-temperature technique. The crystallographic features…

Quantum Groups, Strings and HTSC materials II

Sher Alam, M. O. Rahman, T. Yanagisawa +1

Previously we have indicated the relationship between quantum groups [Phys. Lett A272, (2000)] and strings via WZWN models in the context of applications to cuprates and related ma…

Quantum Groups, Strings and HTSC materials

Sher Alam, M. O. Rahman, T. Yanagisawa +1

Previously we have indicated the relationship between quantum groups and strings via WZWN models. In this note we discuss this relationship further and point out its possible appli…

SET based experiments for HTSC materials

Sher Alam, M. O. Rahman, H. Oyanagi +1

The cuprates seem to exhibit statistics, dimensionality and phase transitions in novel ways. The nature of excitations [i.e. quasiparticle or collective], spin-charge separation, s…

Quantum group conjecture and Stripes

Sher Alam

Keeping in mind our conjecture of modelling cuprates and related systems by quantum groups and our claim that the existence of stripes is intimately related to quantum groups and m…
