Bosonic excitations
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. http://qpt.physics.harvard.edu/phys268b/Lec4_Fermions_in_one_dimension.pdf
