Research news on 1-dimensional systems

In physics, 1-dimensional systems are idealized physical models constrained to a single spatial dimension, where all relevant degrees of freedom vary along one coordinate while transverse dimensions are neglected or treated as frozen. Such systems are fundamental in statistical mechanics, condensed matter, and field theory, enabling exact or quasi-exact treatments of phenomena like phase transitions, transport, and quantum correlations. They exhibit distinctive behavior, including enhanced fluctuations, restricted ordering, and nontrivial topological or conformal structures, and are often described by specialized frameworks such as Luttinger liquid theory, integrable spin chains, or exactly solvable lattice and continuum models.

Chiral nanowires can actively change electron spin direction

The phenomenon where electron spins align in a specific direction after passing through chiral materials is a cornerstone for future spin-based electronics. Yet, the precise process behind this effect has remained a mystery—until ...

Fabricating single-photon light sources from carbon nanotubes

Tiny tubes of carbon that emit single photons from just one point along their length have been made in a deterministic manner by RIKEN researchers. Such carbon nanotubes could form the basis of future quantum technologies ...

A simple spin swap reveals exotic anyons

Researchers from the University of Innsbruck, the Collège de France, and the Université Libre de Bruxelles have developed a simple yet powerful method to reveal anyons—exotic quantum particles that are neither bosons ...
