Arbikosov vortex and Heisenberg

In summary, the conversation discusses the properties of Abrikosov vortices in relation to superconductors and their potential as a quantum object. The question is raised about whether these vortex properties would not commute with something due to their quantum nature, and whether there are any uncertainties associated with them. It is mentioned that in general, the superconducting phase commutes with charge, including in phase qubits and potentially in vortex qubits.

Hello,
I'm studying superconductors and I began to wonder about Abrikosov vortices. They possesses a precise quantum flux (h/e), and are also localized in space enough to be exactly pin-pointed by experimental techniques. As it is some kind of a quantum object, shouldn't these vortex properties not commute with something? Are there any quantum uncertainties associated with it?

Generally speaking, the superconducting phase commutes with charge(=the number of Cooper pairs). This is certainly true for phase qubits, and although I don't remember the details I assume the same would be true for e.g. a vrotex qubit (not that anyone has even succesfully demonstrated one)
 

Related to Arbikosov vortex and Heisenberg

1. What is an Arbikosov vortex?

An Arbikosov vortex, also known as an Abrikosov vortex, is a type of topological defect that occurs in superconductors. It is a localized region of magnetic flux that is trapped within the superconductor, surrounded by a circulating supercurrent.

2. How does the presence of Arbikosov vortices affect the properties of superconductors?

The presence of Arbikosov vortices can significantly impact the behavior of superconductors. They can increase the resistance to current flow, decrease the critical current at which the superconductor transitions to a normal state, and affect the magnetic properties of the material.

3. What is the connection between Arbikosov vortices and Heisenberg's uncertainty principle?

The presence of Arbikosov vortices in a superconductor is a manifestation of the quantum-mechanical phenomenon known as the Meissner effect. This effect is a consequence of the Heisenberg uncertainty principle, which states that it is impossible to know the position and momentum of a particle with absolute certainty.

4. Can Arbikosov vortices be observed experimentally?

Yes, Arbikosov vortices have been observed experimentally through various techniques such as scanning tunneling microscopy and muon spin rotation. These methods allow scientists to visualize and study the behavior of vortices in superconductors.

5. Are Arbikosov vortices relevant in other fields of physics?

Yes, Arbikosov vortices are also relevant in other areas of physics, such as in the study of neutron stars and in the field of high-temperature superconductivity. They also have applications in technologies such as magnetic levitation and quantum computing.
