In physics, 2-dimensional systems are idealized physical systems whose relevant degrees of freedom are confined to a plane or an effectively two-dimensional manifold, such that dynamics and interactions occur predominantly within two spatial dimensions. They exhibit distinct phenomena compared with three-dimensional counterparts, including modified density of states, altered screening and fluctuation behavior, and dimensionality-dependent phase transitions (e.g., Kosterlitz–Thouless transitions mediated by topological defects). Examples include electrons in quantum wells or at interfaces, ultrathin films, and certain spin or lattice models defined on 2D lattices, which serve as fundamental platforms for studying critical phenomena, topological phases, and low-dimensional quantum many-body effects.
A study published in Molecules and led by researchers from the Changchun Institute of Optics, Fine Mechanics and Physics (CIOMP) of the Chinese Academy of Sciences demonstrated how deep learning can streamline the identification ...

Topological spin textures, spatially organized patterns linked to the intrinsic angular momentum of particles, have proved to be highly advantageous for the development of spintronics and quantum technologies. One of the ...
Sliding ferroelectrics are a type of two-dimensional (2D) material realized by stacking nonpolar monolayers (atom-thick layers that lack an electric dipole). When these individual layers are stacked, they produce ferroelectric ...
Scientists have created a new way to characterize graphene oxide (GO) more cheaply and quicker than ever before, helping get the emerging technology out of the lab and into the market.
