Physics 255: Einstein's General Relativity and Gravitation
Physics 255: Einstein's General Relativity and Gravitation (Spring 2014, UC Irvine). Instructor: Professor Herbert W. Hamber. This course provides an introduction to Einstein's theory of gravitation, covering topics: a history of gravity, tensor analysis, Einstein's field equations, astronomical tests of Einstein's theory, and gravitational waves. References used for the class include "Gravitation and Cosmology" by S. Weinberg, "Gravity: An Introduction to Einstein's General Relativity" by J. Hartle, "Lectures on Gravitation" by R.P. Feynman and "Quantum Gravitation" by H.W. Hamber.
| Lecture 20 - Gravitation and Quantum Mechanics |
Topics: Gravitational Field as a Collection of Gravitons, Quantum-Mechanical Field Fluctuations, The Path Integral Approach to Gravity and the Need to Retain General Covariance, DeWitt's Functional Measure over Metrics, Feynman's Derivation of the Field Equations for Gravity from the Construction of a Lagrangian for a Massless Spin-Two Particle, Nonlinear Terms due to the Graviton's own Energy and Momentum, Short Distance Modifications to Gravity due to Radiative Corrections
