Если и не сами решеточные вычисления, то хотя бы вводная часть мне пригодится. Там есть много полезных ссылок, в т.ч. на классику.

О другом, но еще более полезно и понятно. Памяти Вальтера Грайнера:

Photon Scattering off Nuclei: https://arxiv.org/abs/1711.07718

The study of nuclear and subnuclear structure by means of photon scattering is outlined. Besides a brief exposition of the formalism a few illustrative examples are discussed.

Что ж такое, третий раз пост переделываю. Еще вкусность обнаружилась:

Relativistic particle in a box: Klein-Gordon vs Dirac Equations: https://arxiv.org/abs/1711.06313

The problem of a particle in a box is probably the simplest problem in quantum mechanics which allows for significant insight into the nature of quantum systems and thus is a cornerstone in the teaching of quantum mechanics. In relativistic quantum mechanics this problem allows also to highlight the implications of special relativity for quantum physics, namely the effect that spin has on the quantized energy spectra. To illustrate this point, we solve the problem of a spin zero relativistic particle in a one- and three-dimensional box using the Klein-Gordon equation in the Feshbach-Villars formalism. We compare the solutions and the energy spectra obtained with the corresponding ones from the Dirac equation for a spin one-half relativistic particle. We note the similarities and differences, in particular the spin effects in the relativistic energy spectrum. As expected, the non-relativistic limit is the same for both kinds of particles, since, for a particle in a box, the spin contribution to the energy is a relativistic effect.
