Many quasi-one-dimensional (1D) materials are experimental approximations to the
textbook models of Peierls instabilities and collective excitations in 1D electronic systems …

Several approaches for surface-sensitive conductance measurements are reviewed.
Particular emphasis is placed on nanoscale multi-point probe techniques. The results for two …

It has been a long-standing goal to create magnetism in a non-magnetic material by
manipulating its structure at the nanoscale. Many structural defects have unpaired spins; an …

Pt deposited onto a Ge (001) surface gives rise to the spontaneous formation of atomic
nanowires on a mixed Pt-Ge surface after high-temperature annealing. We study possible …

Gold atom chains on vicinal Si (111) surfaces exhibit an unusual doublet of half-filled bands,
whose origin has remained uncertain. The splitting is identified by angle-resolved …

Soliton molecules, bound states of two solitons, can be important for the informatics using
solitons and the quest for exotic particles in a wide range of physical systems from …

Localized modes in one-dimensional (1D) topological systems, such as Majonara modes in
topological superconductors, are promising candidates for robust information processing …

Stabilization of the Si (553) surface by Au adsorption results in two different atomically
defined chain types, one of Au atoms and one of Si. At low temperature these chains …

A structural model of Au induced Si (553) surface is proposed. The model is based on the
recently revised value of Au coverage of 0.48 monolayers, which suggests the formation of …

We investigated phase defects in a quasi-one-dimensional commensurate charge-density
wave (CDW) system, an In atomic wire array on Si (111), using low temperature scanning …
