Un...I am sorry Eugene, my english is not good. I try my best to clarify my question.
The authors said:
"we can generate a description of the system at time zero with respect to a second reference frame translated an amount t in time by letting F represent the state of the system in the second...
After reading few pages of this paper, I got stuck.
Before posting my question, let me summarize the common abstract mathematical structure described in section 2 of this paper for both classical and quantum mechanics.
1)
Let R be a real inear space with lie braket define on it ie. R is a...
So...Is that means since in real world particles can be created and annihilated,
and a field theory can describe a such process a point like particle model can not,
therefore a project which use point like particle quantization scheme is dead?
Dear all,
Since standard QM textbook Sakurai or Shankar only mention Non-relativistic path
integral and QFT text deal with path integral for field theory, I want to ask whether
there is a subject like "Path Intergral quantization for Relativistic point like Particles"?
If so, is this subject...
software to calculate simple commutator relation ??
Dear All:
I have hundred terms of commutators needs to be calculate. Each one looks like
[{\epsilon_{i m}}^n\eta^m\frac{\partial}{\partial\eta^n},C\eta_j\eta^l\frac{\partial}{\partial\theta^l}]
,where C is function of \theta^i and...
