Snell's law for the Schwarzschild black hole
X H Zheng, J X Zheng
The Wheeler equation, for electromagnetic disturbances in a gravitational field, was found by Fiziev to have exact solutions both above and below the event horizon, in the form of…
Seeking high temperature superconductors in ambient from exemplary beryllium-based alloys
X. H. Zheng, J. X. Zheng
With the help of the McMillan formula and virtual crystal model, we predict may exceed 34 K in a beryllium-based alloy with a specific composition, reminiscent of = 35…
Prospects to attain room temperature superconductivity
X. H. Zheng, J. X. Zheng, D. G. Walmsley
With a generic model for the electron-phonon spectral density, two simple expressions are derived to estimate the transition temperature and gap-to-temperature ratio in conventiona…
Umklapp scattering of pairs in BCS superconductivity theory
X. H. Zheng, D. G. Walmsley
The BCS theory of superconductivity is extended to recognize pairing of electrons by both normal and umklapp scattering. Application of the variational approach shows that coexiste…
Umklapp scattering and electron pairing cutoff in BCS superconductors
X. H. Zheng, D. G. Walmsley
In a superconductor electrons form pairs for which the end states of normal and umklapp scattering may overlap. This cuts electron pairing off at a phonon frequency, , low com…
