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.

Quantum simulations reveal spin transport in 1D materials

Researchers from the Department of Energy's Quantum Science Center (QSC) headquartered at Oak Ridge National Laboratory (ORNL) have achieved a significant milestone by demonstrating the first digital quantum simulations of ...

'Poor man's Majoranas' can be used as quantum spin probes

A Majorana fermion is a particle that would be identical to its antiparticle. Such an object has not yet been found. However, certain solid materials exhibit analogous behavior as if Majorana fermions were present through ...

Why you can't tie knots in four dimensions

We all know we live in three-dimensional space. But what does it mean when people talk about four dimensions? Is it just a bigger kind of space? Is it "space-time," the popular idea which emerged from Einstein's theory of ...
