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…

Theoretical modeling for quantum liquids from 1d to 2d dimensional crossover using quantum groups

Sher Alam, M. O. Rahman

Recent experimental and theoretical work in strongly correlated electron system necessitates a formulation to deal with 1d to 2d dimensional crossover and raises several interestin…
