The adhesive performances of a PSA (Pressure Sensitive Adhesive) are attributed to their viscoelastic properties. In this paper we analyze the viscoelastic behavior of different PSAs having substantially similar adhesive performance. Linear and non linear analyses were performed using small amplitude oscillatory shear tests and tensile stress-strain tests, respectively. It is shown that linear ...

A reliable single photon source is a prerequisite for linear optical quantum computation and for secure quantum key distribution. A criterion yielding a conclusive test of the single photon character of a given source, attainable with realistic detectors, is therefore highly desirable. In the context of heralded single photon sources, such a criterion should be sensitive to the effects of highe...
