Black Hole Thermodynamics,During last lecture, we discussed black hole thermodynamics and mechanics. The zero’th law states that surface gravity is constant over an event horizon. For our discussion of the first law we considered Komar quantities.BARGE 发表于 2025-3-27 05:08:15
Quantum Field Theory in Curved Space-Time Backgrounds,The scalar field action is given by .. We promote the field . to an operator . with associated creation and annihilation operators, which we can then make time-dependent asDecongestant 发表于 2025-3-27 08:25:56

Special Relativity,tial distances (as well as temporal intervals) invariant. For example, in two spatial dimensions with coordinates (., .), the squared distance . is invariant under rotations, which are of the form . The invariance of spatial (Euclidean) distance is then given by ..CHART 发表于 2025-3-28 01:42:04

Black Holes,is compressed into a small region of space-time. It is characterized by a curvature singularity at the origin which is ‘screened’ to outside observers by a coordinate singularity at finite radial distance. This coordinate singularity is known as the ., which will be seen to exhibit deep connections with thermodynamic systems.赔偿 发表于 2025-3-28 06:14:34
