In the context of physical systems, 3-dimensional systems are systems whose relevant degrees of freedom are embedded in or constrained by three spatial dimensions, typically described by coordinates (x, y, z) in Euclidean space. Their behavior is governed by field equations or dynamical laws defined over a 3D manifold, such as Maxwell’s equations, Navier–Stokes equations, or Schrödinger’s equation in three spatial dimensions. These systems exhibit phenomena inherently dependent on 3D geometry and topology, including volumetric interactions, three-component vector fields, and spatially resolved boundary conditions, and they often require tensorial or vector calculus formalisms for accurate modeling and analysis.
It has been revealed that simply twisting and stacking two layers of oxide crystals can allow the atomic arrangement itself to control the behavior of electrons. Much like the new patterns that emerge when two meshes are ...

For the first time, physicists in Italy have created a 'lump soliton': an extremely stable packet of light waves which can travel through 3D space, and even interact with other solitons without losing its shape.
In future high-tech industries, such as high-speed optical computing for massive AI, quantum cryptographic communication, and ultra-high-resolution augmented reality (AR) displays, nanolasers—which process information using ...
