Spin Effects In The Effective Quantum Field Theory Of General Relativity, A Ross, Br Holstein Jun 2007

Spin Effects In The Effective Quantum Field Theory Of General Relativity, A Ross, Br Holstein

Barry R Holstein

The calculation of gravitational scattering of particles with various spin configurations in the framework of effective quantum field theory of general relativity is presented. We find that the long-range quantum and classical corrections to the spin-independent piece and the spin–orbit coupling piece of the scattering amplitude and the scattering potential are universal for different spin configurations, which leads us to propose this universality to be true for arbitrary spins. Furthermore, we give the leading corrections to the spin–spin coupling, and a comparison with scattering in QED is made.

Angular Dependent Magnetorestriction Study Of Cecoin5, Catalin Martin, Victor Correa, Kenneth Purcell, Timothy Timothy, Eric Palm, Stanley Tozer, George Schmiedeshoff, J Cooley

George Schmiedeshoff

Using a capacitive dilatometer designed to operate on the rotating stage of a top loading dilution refrigerator probe, we measured the magnetorestriction ( L(H)-L(0))/L(0), of the Heavy Fermion Superconductor CeCoIn5, along all three crystallographic direction, and with the magnetic field applied parallel both to the superconducting ab-planes and to the c-axis. When B||ab, the c-axis magnetorestriction features, besides a sharp jump at the upper critical field, a continuous, second-order like, transition at a lower field, which is consistent with previous observations from specific heat measurements. Our results are consistent with a field induced modulation of the superconducting order parameter (FFLO …
