On magnetic field screening and trapping in hydrogen-rich high-temperature superconductors: unpulling the wool over readers' eyes
J. E. Hirsch, F. Marsiglio
In Nat Commun 13, 3194 (2022) [1], Minkov et al. reported magnetization measurements on hydrides under pressure that claimed to find a diamagnetic signal below a critical temperatu…
Extended Comment on Nature 586, 373 (2020) by E. Snider et al
Dirk van der Marel, Jorge E Hirsch
Recently the discovery of room-temperature superconductivity was announced for a carbonaceous sulfur hydride (CSH) under high pressure. The evidence for superconductivity was based…
On the ac magnetic susceptibility of a room temperature superconductor: anatomy of a probable scientific fraud
J. E. Hirsch
In Nature 586, 373 (2020), Snider et al announced the experimental discovery of room temperature superconductivity in a carbonaceous sulfur hydride under high pressure, hereafter c…
On the dynamics of the Meissner effect
J. E. Hirsch
The question of how a metal becoming superconducting expels a magnetic field is addressed. It is argued that the conventional theory of superconductivity has not answered this ques…
The London moment: what a rotating superconductor reveals about superconductivity
J. E. Hirsch
The London moment is the magnetic moment acquired by a rotating superconductor. We propose that the London moment reveals the following fundamental properties of the superconductin…
Superconductivity, diamagnetism, and the mean inner potential of solids
J. E. Hirsch
The mean inner potential of a solid is known to be proportional to its diamagnetic susceptibility. Superconductors exhibit giant diamagnetism. What does this say about the connecti…
Dynamic Hubbard model: kinetic energy driven charge expulsion, charge inhomogeneity, hole superconductivity, and Meissner effect
J. E. Hirsch
Dynamic Hubbard models describe the fact that the wavefunction of an electron in an atomic orbital expands when a second electron occupies the orbital. These models give rise to su…
The origin of the Meissner effect in new and old superconductors
J. E. Hirsch
It is generally believed that superconducting materials are divided into two classes: `conventional' and `unconventional'. Conventional superconductors (the elements and thousands…
Did Herbert Fröhlich predict or postdict the isotope effect in superconductors?
J. E. Hirsch
Herbert Fröhlich is generally credited with having predicted the fundamental role of electron-phonon interactions in superconductivity in 1950, and in particular the isotope effect…
