This text presents the statistical mechanics of solids from the perspective of the material properties of the solid state, and discusses theories of harmonic crystal, free electrons in metal and ...

Named after the German engineer Georg Duffing, the system was originally utilized to resolve complex physical questions and to analyze anharmonic oscillations. Once it became popular, it was used ...

including an anharmonic contribution of 0.4 kJ mol−1),” the study authors note. Moreover, unlike bare copper ions, the copper ...

At its core, the transmon uses a Josephson junction, which is a type of superconducting tunnel junction. The transmon possesses anharmonic energy levels, meaning energy levels are not equally spaced.
