A method to detect fermionic magnetic monopoles?

In summary, the conversation discusses the potential detection of monopoles using electric methods, specifically by looking for an intrinsic electric dipole moment in fermionic monopoles and testing their response to electromagnetic radiation at specific frequencies. However, it is suggested that this method may not be effective due to the expected zero spin and angular momentum of bound fermionic monopoles.

Monopoles have never been detected using magnetic methods. Perhaps that is because they now exist as bound states of North and South monopoles and therefore act only as magnetic dipoles rather than magnetic poles.

I propose an electric method that might detect even bound monopole states.

If there exist magnetic monopoles that are fermions then each should have an instrinsic electric dipole moment by analogy with electrons that have a magnetic dipole moment.

Would the electric spin energy level be split if the monopole is put inside a strong electric field?

By analogy with NMR, if one then radiated the monopoles with electromagnetic radiation at the right resonant frequency would the monopoles absorb it?

If the dark matter consists of fermionic monopoles one could try to detect them crossing through a box by putting a high electric field across it and then radiating the inside of the box with EM waves at different frequencies and looking to see if any frequencies are absorbed.

I guess that this won't work as the bound state of fermionic monopoles will actually have zero spin altogether as the fermions will be aligned opposite each other. The angular momentum will also be zero as the fermionic monopoles will be in a symmetric s-orbital.
 

1. What is a fermionic magnetic monopole?

A fermionic magnetic monopole is a hypothetical elementary particle that carries a magnetic charge, similar to how an electron carries an electric charge. However, unlike the electron which has a negative charge, the fermionic magnetic monopole is predicted to have a positive or negative magnetic charge. This means that it would act as a single magnetic pole, either a north or south pole, rather than having both poles like a typical magnet.

2. Why is it important to detect fermionic magnetic monopoles?

If fermionic magnetic monopoles are found to exist, it would revolutionize our understanding of electromagnetism and fundamental particles. It would also have significant implications for the unification of the four fundamental forces of nature, as well as potential applications in technology such as magnetic storage and energy generation.

3. What is the proposed method to detect fermionic magnetic monopoles?

The proposed method involves using a superconductor to create a topological defect in the material, known as a vortex line. If a fermionic magnetic monopole passes through this vortex line, it would create a signature in the form of a quantized charge transfer. This charge transfer could be detected using specialized equipment, such as a SQUID (Superconducting Quantum Interference Device).

4. How would the detection of fermionic magnetic monopoles be confirmed?

In addition to the charge transfer signature, the detection of fermionic magnetic monopoles would also need to be confirmed through other experimental evidence, such as the measurement of their magnetic charge and other physical properties. Additionally, the results would need to be reproduced and verified by independent research groups.

5. What are the current challenges in detecting fermionic magnetic monopoles?

The main challenge in detecting fermionic magnetic monopoles is that they are predicted to be very rare and highly energetic particles. This means that specialized equipment and techniques are needed to create the conditions for their detection. Additionally, there is a possibility that they may not exist at all, making it difficult to design experiments that can definitively prove their existence.
