Interesting. Do we know if it possible to disrupt superconductivity with sound at just the right frequency? And the converse, has anyone tried to enhance superconductivity by using sound (i.e. increase either the critical temperature, increase the current density, etc)?
- opwieurposiu 6y agoHTS will stop superconducting once a certain amount of energy is added. This energy can be in the form of heat, magnetic field, electric current, or mechanical strain. If you keep the HTS colder you can accommodate more of the other forms of energy. I do not know if sound would disrupt superconductivity but since sound is a form of energy it is very likely. https://www.nature.com/articles/s41598-019-50266-1 https://www.nature.com/articles/s41598-019-50266-1
