A bstract We present the two-body Hamiltonian and associated eikonal phase, to leading post-Minkowskian order, for infinitely many tidal deformations described by operators with arbitrary powers of curvature tensor. Scattering amplitudes in momentum position space provide systematic complementary approaches. For quadratic curvature, which describe linear response an external gravitational field...

The requirements of high quality factor, low power consumption, easy design techniques and compatibility with the main standard fabrication processes integrated circuits (IC) make tunable piezoelectric resonators a suitable option for new technologies fifth generation telecommunication (5G) Internet Things (IoT). In this work nonlinear state equations effect are presented. From these we may ded...
