THz imaging in quantum Hall conductors and superconductors. Gravitational energy density and gradients

Susumu Komiyama,

I was looking for your paper, “Electron temperature of hot spots in quantum Hall conductors” and found this THz imaging paper on ResearchGate. I think at zero temperature the magnetic energy density and its gradients are important. “hot spots” are just part of it. I was looking at ways to push the fields into the region of 100 to 1000 Tesla. The MagLab can do 101 T, but they made the bore larger than it needs to be. Beneq.com can fabricate a wide range of multiatom layers. I was looking to see if pulsed 0.4 KiloTesla field at low power could be used with faster sensors. Your THz method might work, but I am not sure without reading your papers.  The magnetic gradient can trigger transitions and flows, so the total power is not important, but the magnetic energy density and its gradients.

I am coming at this looking for better gravitational sensors, and found that the magnetic and gravitational acceleration fields  are equivalent in many cases, using their respective energy densities.  Only in the last few years are the magnetic fields getting to the where they are comparable to the gravitational energy density at the Earth’s surface, about 380 Telsa.  Most of the “quantum” fluctuations at zero temperature are likely a mixture of gravitational and magnetic energy density effects.  And they are frequency dependent.

But the gravitational field is most likely a Boson supercritical fluid made of magnetically (mostly dipole) coupled Fermion pairs very tiny at about 300K energy (0.025 eV).  Most of these “quantum” detectors should couple to the gravitational field which is time dependent at any location.
