Metric and Curvature in Gravitational Phase Space
At a fixed point in spacetime (say, x0), gravitational phase space consists of the space of symmetric matrices {F ab} [corresponding to the canonical momentum π(x0)] and of symmetric matrices {Gab} [corresponding to the canonical metric gab(x0)], where 1 ≤ a, b ≤ n, and, crucially, the matrix {Gab} is necessarily positive definite, i.e. ∑ uGabu b > 0 whenever ∑ (ua)2 > 0. In an alternative quan...
متن کاملA phase-space beam position monitor for synchrotron radiation
The stability of the photon beam position on synchrotron beamlines is critical for most if not all synchrotron radiation experiments. The position of the beam at the experiment or optical element location is set by the position and angle of the electron beam source as it traverses the magnetic field of the bend-magnet or insertion device. Thus an ideal photon beam monitor would be able to simul...
متن کاملA Phase Space Approach to the Gravitational Arrow of Time
As the universe evolves, it becomes more inhomogeneous due to gravitational clumping. We attempt to find a function that characterizes this behavior and increases monotonically as inhomogeneity increases. We choose S = ln Ω as the candidate “gravitational entropy” function, where Ω is the phase-space volume below the Hamiltonian H of the system under consideration. We perform a direct calculati...
متن کاملTitle: Oscillators and Phase Locked Loops for Space Radiation Environments Oscillators and Phase Locked Loops for Space Radiation Environments
approved: _____________________________________________________ Un-Ku Moon Kartikeya Mayaram Circuits operating outside the earth’s atmosphere are more vulnerable to cosmic radiation and require special design consideration. The purpose of this work is to explore methods of mitigating the effect of radiation in phase locked loop (PLL) circuits. Several voltage controlled oscillators (VCOs) and ...
متن کاملGravitational Radiation *
Gravity is one of the fundamental forces of Nature, and it is the dominant force in most astronomical systems. In common with all other phenomena, gravity must obey the principles of Special Relativity. In particular, gravitational forces must not be transmitted or communicated faster than light. This means that when the gravitational field of an object changes, the changes ripple outwards thro...
