Distortion of frustrated spin cluster caused by quantum fluctuation due to magneto-elastic coupling

We study the effects of magneto-elastic coupling on frustrated spin states of the antiferromagnetic Heisenberg model on a regular triangle and tetrahedron made of spin 1/2 or 1. Displacement of spin is considered as a quantum-mechanical variable. Distortion of clusters occurs through quantum fluctua...
