Abstract
We prove that quantum fluctuations can suppress structural phase trans itions. We give a rigorous proof for a one-component (R(1)) quantum cr ystal with local double-well anharmonism under the condition that the masses of the atoms in the lattice sites of Z(d) (d greater than or eq ual to 3) are light enough.
