Averaged Energy Inequalities for Non-Minimally Coupled Classical Scalar Fields |
Abstract _ |
The stress energy tensor for the non-minimally coupled scalar field is known not to satisfy the point wise energy conditions, even on the classical level. We show, however, that local averages of the classical stress energy tensor satisfy certain inequalities and give bounds for averages along causal geodesics. It is shown that in vacuum background spacetimes, ANEC and AWEC is satisfied. Furthermore we use our result to show that in the classical situation we have an analogue to the so called quantum interest conjecture. These results lay the foundations for average energy inequalities for the quantized non-minimally coupled fields. |
