While quantum mechanics explains the small-scale, low-energy behavior of electrons, relativity becomes important when those same electrons move fast enough for strange effects like spin-orbit coupling ...

"God does not play dice." This famous remark by Albert Einstein critiqued the probabilistic nature of quantum mechanics.

Topological materials are a class of materials that exhibit unique electronic properties at their boundary (surface in 3D materials; edge in 2D materials) that are robust against imperfections or ...
