Orbits of a Killing vector field

Click For Summary
The discussion centers on the concept of orbits of a Killing vector field, defined as solutions to the differential equation involving a vector field V^\mu(x). These orbits, denoted as Z^\mu(\lambda), represent paths that follow the vector field's direction. A key resource mentioned is Hall's book on symmetries in general relativity, which is highly regarded by participants. The definition provided serves as a foundation for further calculations and clarifications. Overall, the conversation emphasizes the mathematical framework and resources for understanding Killing vector fields and their orbits.

I was wondering what the orbits of a Killing vector field are. Do you have any good sources or reading material for this?

Given a (not necessarily Killing) vector field V^\mu(x), its "orbits" are solutions Z^\mu(\lambda) to the differential equation \dot{Z}^\mu(\lambda) = V^\mu(Z(\lambda)), where the dot is a \lambda derivative. Intuitively, an orbit just "follows the little arrows of the vector field".

That's all there is to it.

Thanks Sam. I'll do some calculations with this definition and come back if I have further clarifications.
 
Hall's book on symmetries in GR is my favorite, I'd go so far as to say, I love it.
 
In an inertial frame of reference (IFR), there are two fixed points, A and B, which share an entangled state $$ \frac{1}{\sqrt{2}}(|0>_A|1>_B+|1>_A|0>_B) $$ At point A, a measurement is made. The state then collapses to $$ |a>_A|b>_B, \{a,b\}=\{0,1\} $$ We assume that A has the state ##|a>_A## and B has ##|b>_B## simultaneously, i.e., when their synchronized clocks both read time T However, in other inertial frames, due to the relativity of simultaneity, the moment when B has ##|b>_B##...
