WebDec 13, 2024 · This structure is unique to phononic systems as the spin-orbit coupling present in electronic systems tends to lift the degeneracy away from high-symmetry … WebQuasiparticle. In physics, quasiparticles and collective excitations are closely related emergent phenomena arising when a microscopically complicated system such as a solid behaves as if it contained different weakly interacting particles in vacuum. For example, as an electron travels through a semiconductor, its motion is disturbed in a ...

WebOur results open the door for research on topological magnonics as well as other bosonic excitations in nite and disordered systems. Topological phases in nature have attracted intense in-terest and research in recent decades. Initially, the re-search was mainly on electronic systems such as topo-logical insulators [1,2].

WebAug 8, 2024 · Abstract We identify the bosonic excitations in ferroelectrics that carry electric dipoles from the phenomenological Landau-Ginzburg-Devonshire theory. The “ferron” quasiparticles emerge from the concerted action of anharmonicity and broken inversion symmetry. cmhcf phone number
