Crystalline systems are physical systems in which constituent particles (atoms, ions, or molecules) are arranged in a periodic lattice that exhibits long-range translational order. They are characterized by discrete symmetry operations described by space groups, with unit cells repeating periodically in one, two, or three dimensions. This periodicity gives rise to well-defined Brillouin zones, phonon dispersion relations, and electronic band structures, which critically determine mechanical, optical, thermal, and electronic properties. Crystalline systems serve as fundamental models in condensed matter physics for studying phase transitions, defects (dislocations, vacancies), and emergent phenomena such as superconductivity and ferroelectricity.
Vacuum ultraviolet (VUV, 100–200 nm) light sources are indispensable for advanced spectroscopy, quantum research, and semiconductor lithography. Although second harmonic generation (SHG) using nonlinear optical (NLO) crystals ...

Charge density waves (CDWs) are ordered, crystal-like patterns in the arrangement of electrons that spontaneously form inside some solid materials. These patterns can change how electricity flows through materials, in some ...
It has been revealed that simply twisting and stacking two layers of oxide crystals can allow the atomic arrangement itself to control the behavior of electrons. Much like the new patterns that emerge when two meshes are ...
