Posted on April 14, 2023, by Yuanpeng Zhang
Reversing the transformation from reciprocal space to real space given an experimentally measured diffraction pattern is difficult in practice since the phase information is lost in the experimental diffraction measurement and we are left with only the intensities of the Bragg spots. The Fourier map approach is one of commonly...

Magnetic ions in crystals
Posted on March 29, 2020, by Yuanpeng Zhang
Talking about the magnetism of ions in crystals naturally brings us out of the atomic physics picture which we previously based ourselves in when discussing the free atom and ions (see previous note by clicking me!). Also, for sure we should turn to the many-electron scheme instead of a single-electron...

Magnetism of free atoms and ions
Posted on March 18, 2020, by Yuanpeng Zhang
To understand the magnetism of free atoms and ions, we may go through several stages, as follows,
Hartree approximation - electrons are treated in a non-interactive manner.
Beyond Hartree - interaction between electrons is taken into account.
Spin-orbital coupling.
Hyperfine interaction - the interaction between electrons and nucleus.

After evaporation, the gas should be liquefied back to liquid form to finish the cycle, and of course, the process of liquefaction will emit heat. That’s...
