This article reviews the static and dynamic properties of spontaneous superstructures
formed by electrons. Representations of such electronic crystals are charge density waves …

Coordination polymers are currently one of the hottest topics in Inorganic and
Supramolecular Chemistry. This critical review summarizes the current state-of-the-art on …

Historically most materials in magnetic applications are based on inorganic materials.
Recently, however, organic and molecular materials have begun to show increasing …

Inorganic compounds with the AB2X4 spinel structure have been studied for many years,
because of their unusual physical properties. The spinel crystallographic structure, first …

The magnetic properties of CuGe O 3 are shown to be well described by the one-
dimensional Heisenberg S= 1 2 model with competing antiferromagnetic interactions …

Spontaneous symmetry breaking—the phenomenon in which an infinitesimal perturbation
can cause the system to break the underlying symmetry—is a cornerstone concept in the …

Some molecular/organic solids comprised of linear chains of alternating metallocenium
donors (D) and cyanocarbon acceptors (A) with spin state S= 1/2 (⋅⋅⋅ D⋅+ A⋅-D⋅+ A⋅ …

We report spin wave and density-matrix renormalization-group (DMRG) studies of the
ground and low-lying excited states of uniform and dimerized alternating spin chains. The …

We study numerically, using a one-dimensional Heisenberg model coupled to the lattice in
the adiabatic approximation, the spin-Peierls transition in the linear Cu 2+ spin-1/2 chains in …
