In summary, the conversation discusses the four potential that yields a photon and the reason for it being a 4-field. The gauge field of the EM-interaction is mentioned as an example, which exhibits U(1) gauge invariance. The functions a, b, c, and d in the four potential may depend on multiple variables.

The gauge field of the EM-interaction.

edit : let me ask you this question : "Do you know why a quantumfield yielding a photon must be a 4-field ?"

of course gauge invariance. The e-m exhibits U(1) gauge invariance. (but feel free to remind me about anything of this)

A four potential looks like this: a(q) +b(x)i + c(y)j+ d(z)k
I´m just too lazy to calculate them and have never really done it, but I need to know an example of a(q), b(x), c(y), d(z) for a photon.

ok, can´t find the edit button, but of course functions a, b, c, d in the last message depend on more than one variable (perhaps all q, x, y, z).
 

FAQ: What Is a Four Potential That Yields a Photon?

What is a "Four Potential Yields Photon"?

A "Four Potential Yields Photon" refers to a theoretical concept in quantum mechanics where a single photon can potentially produce four different outcomes or "yields" depending on how it is measured or observed. This idea challenges the traditional understanding of a photon as having only one possible outcome when measured.

How is the concept of "Four Potential Yields Photon" relevant to science?

The concept of "Four Potential Yields Photon" has significant implications in quantum physics and the study of light. It challenges our understanding of the fundamental nature of particles and how they behave. It also has practical applications in technologies such as quantum computing and cryptography.

What evidence supports the existence of "Four Potential Yields Photon"?

Several experiments have been conducted to demonstrate the existence of "Four Potential Yields Photon." These include the delayed choice quantum eraser experiment and the quantum entanglement experiment. These experiments show that a single photon can exhibit behavior that is not possible under classical physics.

How does the concept of "Four Potential Yields Photon" relate to the wave-particle duality of light?

The concept of "Four Potential Yields Photon" is closely related to the wave-particle duality of light. It suggests that a photon can manifest as both a wave and a particle simultaneously, with multiple potential outcomes. This challenges the traditional understanding of light as either a wave or a particle.

What are the implications of "Four Potential Yields Photon" for our understanding of the universe?

The existence of "Four Potential Yields Photon" raises questions about the nature of reality and the fundamental laws of physics. It challenges our understanding of cause and effect and the role of observation in shaping reality. Further research in this area may lead to new discoveries and a deeper understanding of the universe.
