Diagrams
2020
Diagrams are two-dimensional representations of a domain in which relations among elements like points, lines, open/bounded regions on a plane match relations among the elements of that domain. Diagrams are means of surrogate reasoning, namely of exploring the possibilities to reduce or eliminate the uncertainty imparted by a problem through operations on external aids. The study of diagrams addresses formal and cognitive issues.
Competition of electron-phonon mediated superconductivity and Stoner magnetism on a flat band
2018
The effective attractive interaction between electrons, mediated by electron-phonon coupling, is a well-established mechanism of conventional superconductivity. In metals exhibiting a Fermi surface, the critical temperature of superconductivity is exponentially smaller than the characteristic phonon energy. Therefore, such superconductors are found only at temperatures below a few kelvin. Systems with flat energy bands have been suggested to cure the problem and provide a route to room-temperature superconductivity, but previous studies are limited to only BCS models with an effective attractive interaction. Here we generalize Eliashberg's theory of strong-coupling superconductivity to syst…
