Summary: | Phys. Lett. A272, (2000), 107-112 Following our recent conjecture to model the phenomenona of
antiferromagnetism and superconductivity by quantum symmetry groups, we propose
in the present note three toy models, namely, one based on SO_{q}(3) the other
two constructed with the SO_{q}(4) and SO_{q}(5) quantum groups. Possible
motivations and rationale for these choices are outlined. One of the prime
motivations underlying our proposal is the experimental observation of stripe
structure [phase] in high T_c superconductivity [HTSC] materials. A number of
experimental techniques have recently observed that the CuO_{2} are rather
inhomogeneous, providing evidence for phase separation into a two component
system. i.e. carrier-rich and carrier-poor regions. In particular, extended
x-ray absorption fine structure [EXAFS] demonstrated that these domains forms
stripes of undistorted and distorted local structures alternating with
mesoscopic length scale comparable with coherence length in HTSC.
Evidence for our conjecture is discussed. |
