Exploring Physics Measurement: Stochastic Electrodynamics

[ziyuang]

Hi, there.
I am not major in physics so maybe I lack some basic knowledge.
Imagine one have an ideal sensor, which can convert the emission to some kinds of signal (typically, voltage), then what process can describe the measure data? Is it related to http://en.wikipedia.org/wiki/Stochastic_electrodynamics" ?

Spontaneous electromagnetic radiation is a quantum process. Whereas stochastic electrodynamics is the effort to add some quantum concepts into classical electrodynamics without going full quantum, you could also use stochastic electrodynamics to describe spontaneous emission.

Thanks for your hint. It seems to be something called http://en.wikipedia.org/wiki/Fermi%27s_golden_rule"

 

[chrisbaird]

Fermi's Golden Rule can be used to calculate any transition rate, not just photon emission.

Hello there,

I am familiar with the concept of stochastic electrodynamics. It is a theoretical framework that aims to explain the behavior of electromagnetic fields at the quantum level. It combines elements of classical electrodynamics and quantum mechanics to describe the statistical behavior of electromagnetic phenomena.

In regards to your question about the ideal sensor, the measurement data would likely be described using statistical distributions and equations within the framework of stochastic electrodynamics. This would take into account factors such as the uncertainty and randomness inherent in quantum systems.

While this theoretical framework is still being explored and developed, it has shown promise in providing a deeper understanding of the behavior of electromagnetic fields. I would suggest further research and study to gain a better understanding of stochastic electrodynamics and its applications in measurement and other areas of physics.
