CAN THERE BE A T-3-LN-T KIND OF BEHAVIOR OF THE LOW-TEMPERATURE SPECIFIC-HEAT OF LIQUID-HE-3 WITHOUT THE PARAMAGNONS

It is shown that even without invoking the concepts like paramagnons, the temperature dependence of the interparticle correlations in a syst em of liquid He-3 can give rise a T-3 In T kind of behaviour of its lo w temperature fermionic specific heat. It is found to be coming from t he self-energy corrections to the bare single particle energy involvin g the particle-hole propagator. Looking at the similar kind of behavio ur observed by us recently for an electron liquid, one may conclude th at the T-3 In T behaviour is perhaps universal for all fermi systems, although for liquid He-3 the very dependence also follows from the par amagnon effects. It is interesting to see that unlike earlier theories , an extremely good fit is obtained with the experimental data over th e entire range of low temperatures.
