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…
The patching of critical points using quantum group
Sher Alam, M. O. Rahman, M. Ando +2
Following our recent conjecture to model the phenomenona of antiferromagnetism and superconductivity by quantum symmetry groups, we discuss in the present note how to construct a w…
The choice of the symmetry group for the cuprates
Sher Alam, M. O. Rahman, M. Ando +2
Following our recent conjecture to model the phenomenona of antiferromagnetism and superconductivity by quantum symmetry groups, we discuss in the present note the choice of the cl…
Exciton effects and nonlinear optical response in soliton lattice states of doped conjugated polymers
Kikuo Harigaya, Yukihiro Shimoi, Shuji Abe
Exciton effects on conjugated polymers are investigated in the soliton lattice system. We use the Su-Schrieffer-Heeger model with long-range Coulomb interactions treated by the sin…
