Incommensurate ordering
Webimportance of charge order in understanding and manipulating novel phases of matter (2, 6–9). While the precise microscopic mechanism of charge order-ing remains under intense scrutiny, measurements of modu-lation wave vectors in various materials have established a tendency toward incommensurate order (1, 3, 5, 10–14). The WebJun 1, 2024 · The stability problem of time-delay incommensurate fractional-order systems is formulated in Section 3. In Section 4, first, some conditions are achieved which guarantee the poles of time-delay system are located in a given region. Then, these conditions are used to obtain some conditions for checking the stability.

There are basically three types of superstructures in crystals: When a crystalline material that contains atoms with uncompensated electron spins is cooled down, ordering of these spins generally occurs once the thermal energy is small enough not to overrule the interactions between neighboring spins. If the ordering does not exhibit the same symmetry as the original unit cell of the crystallographic lattice, a superstructure will result. In thi…
