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 …

Condensed matter systems with topological order and metamaterials with left-handed
chirality have attracted recently extensive interests in the fields of physics and optics. So far …

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 …

Chiral objects can be found throughout nature,,,; in condensed matter chiral objects are
often excited states protected by a system's topology. The use of chiral topological …

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 …

One-dimensional (1D) systems have played a crucial role in the development of
fundamental physics and practical applications. Recently, transition metal …

We report on the observation of the hysteretic transition of a commensurate charge
modulation in IrTe 2 from transport and scanning tunneling microscopy (STM) studies. Below …

Starting from a Su-Schrieffer-Heeger-like model inferred from first-principles simulations, we
show that the metal-insulator transition in In/Si (111) is a first-order grand canonical Peierls …

The precise driving force of the phase transition in indium nanowires on Si (111) has been
controversial whether it is driven by a Peierls instability or by a simple energy lowering due …

Recent studies on a quasi-one-dimensional (quasi-1D) charge-density-wave (CDW) system,
In atomic wires on Si (111), have brought intriguing issues on topological solitons in quasi …
