DOI: 10.1088/0256-307x/42/2/027405
Abstract: Topological physics has evolved from its initial focus on fermionic systems to the exploration of bosonic systems, particularly phononic excitations in crystalline materials. Two-dimensional (2D) topological phonons emerge as promising candidates for future technological applications.… read more here.

DOI: 10.1103/physrevmaterials.2.114204
Abstract: Recently published discoveries of acoustic- and optical-mode inversion in the phonon spectrum of certain metals became the first realistic example of noninteracting topological bosonic excitations in existing materials. However, the observable physical and technological use… read more here.
