Physicists show how tight 'diet' could produce single-chirality carbon nanotubes
Like a giraffe stretching for leaves on a tall tree, making carbon nanotubes reach for food as they grow may lead to a long-sought breakthrough.
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.
