摘要：

It is shown that a one to one correspondence between quantum fields in two different ''phases'' as might be realised for pions produced from a ''hadron liquid'' leads to squeezed states. The single and double inclusive cross sections for a chaotic superposition of such states are calculated. The correlation of identical pions is overbunched in comparison with canonical Bose-Einstein correlations.
