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

Wires having a width of one or two atoms are the smallest possible physical objects that may
exhibit one-dimensional properties. In order to be experimentally accessible at finite …

Atom assemblies on surfaces represent the ultimate lower size limit for electronic circuits,
and their conduction properties are governed by quantum phenomena. A fundamental …

Indium-decorated Si atomic chains on a stepped Si (553)–Au substrate are proposed as an
extended Su–Schrieffer–Heeger (SSH) model, revealing topological end states. An …

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 …

Unique electronic properties of self-organized Au atom chains on Ge (001) in novel c (8× 2)
long-range order are revealed by scanning tunneling microscopy. Along the nanowires an …

The bulk-boundary correspondence is an integral feature of topological analysis and the
existence of boundary or interface modes offers direct insight into the topological structure of …

Atomic chains are perfect systems for getting fundamental insights into the electron
dynamics and coupling between the electronic and ionic degrees of freedom in one …
