lattid
Lattid is a hypothetical quasiparticle describing a localized, quantized distortion of a crystalline lattice that can propagate as a stable excitation in nonlinear lattice systems. The concept was introduced in theoretical studies to explore how nonlinearities influence energy transport in nanoscale materials and to distinguish localized lattice distortions from conventional phonons.
In theoretical models, lattids arise as topologically stabilized, breather-like excitations in one- or two-dimensional lattices with
Observation and research into lattids focus on simulations and proposed experimental platforms. Possible routes include ultrafast
Etymology and status: the term lattid is not standard in mainstream condensed-matter physics and remains primarily
