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

In this review article, we present recent studies of peculiar Rashba spin-split energy band
structures appearing at surfaces of metallic and semiconducting substances as well as …

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 …

The ground state property of a Au-induced atomic wire array on a stepped Si (553) surface
with interesting 1D metallic bands was investigated. Electron diffraction and scanning …

We present a variable temperature scanning tunneling microscopy and spectroscopy study
of the Si (553)-Au atomic chain reconstruction. This quasi-one-dimensional system …

The spectroscopy of quasi-one-dimensional (1D) systems has been a subject of strong
interest since the first experimental observations of unusual line shapes in the early 1990s …

We report evidence of a spin-split one-dimensional metallic surface state for the system of Si
(557)-Au obtained by means of spin-and angle-resolved photoelectron spectroscopy …

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 …

Interacting electrons confined to only one spatial dimension display a wide range of unusual
many-body quantum phenomena, ranging from Peierls instabilities to the breakdown of the …

Finite-size effects in charge-density waves (CDWs) were unveiled using scanning tunneling
microscopy for metallic atomic wires on the Au/Si (553) surface, as terminated by adsorbate …
