Predicted electric field near small superconducting ellipsoids
J. E. Hirsch
We predict the existence of large electric fields near the surface of superconducting bodies of ellipsoidal shape of dimensions comparable to the penetration depth. The electric fi…
Electrodynamics of superconductors
J. E. Hirsch
An alternate set of equations to describe the electrodynamics of superconductors at a macroscopic level is proposed. These equations resemble equations originally proposed by the L…
Charge expulsion and electric field in superconductors
J. E. Hirsch
The theory of hole superconductivity predicts that when a metal goes superconducting negative charge is expelled from its interior towards the surface. As a consequence the superco…
The Lorentz force and superconductivity
J. E. Hirsch
To change the velocity of an electron requires that a Lorentz force acts on it, through an electric or a magnetic field. We point out that within the conventional understanding of…
Superconductors as giant atoms: qualitative aspects
J. E. Hirsch
When the Fermi level is near the top of a band the carriers (holes) are maximally dressed by electron-ion and electron-electron interactions. The theory of hole superconductivity p…
Spontaneous spinning of a magnet levitating over a superconductor
J. E. Hirsch, D. J. Hirsch
A permanent magnet levitating over a superconductor is found to spontaneously spin, overcoming resistance to air friction. We explain the physics behind this remarkable effect.
