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

In magnetically controllable ferroelectrics,,, electric polarization is induced by charge
redistribution or lattice distortions that occur to minimize the energy associated with both the …

To study solid materials on the atomic scale one often starts with an ideal crystal at zero
temperature and calculates its electronic structure by means of density functional theory …

We present a detailed angle-resolved photoemission spectroscopy (ARPES) investigation of
the R Te 3 family, which sets this system as an ideal “textbook” example for the formation of …

Using angle-resolved photoemission spectroscopy we demonstrate that a normal-state
pseudogap exists above TN-IC in one of the most studied two-dimensional charge-density …

C e T e 3 is a layered compound where an incommensurate charge density wave (CDW)
opens a large gap (<? format?>≃<? format?> 400 me V) in optimally nested regions of the …

Layered group V transition-metal trichalcogenides are paradigmatic low-dimensional
materials providing an ever increasing series of unusual properties. They are all based on …

The electronic structure of the quasi-one-dimensional organic conductor TTF-TCNQ is
studied by angle-resolved photoelectron spectroscopy (ARPES). The experimental spectra …

The charge density wave (CDW) instability, usually occurring in low-dimensional metals, has
been a topic of interest for longtime. However, some very fundamental aspects of the …

One-dimensional atomic chains on A u/S i (557) feature two proximal 1D bands near the
Fermi level, which were controversially attributed as a spinon-holon pair of a Luttinger liquid …
