We utilize the coset construction to derive the effective field theory of magnon-phonon interactions in (anti)-ferromagnetic and ferrimagnetic insulating materials. The action is used to calculate the equations of motion which generalize the Landau-Lifshitz and stress equations to allow for magneto-acoustic couplings to all orders in the fields at lowest order in the derivative expansion. We also include the symmetry breaking effects due to Zeeman, and Dzyaloshinsky-Moriya interactions. This…

Magnon-phonon hybridization in 2D antiferromagnet MnPSe3

Description

Zeeman term for the Néel vector in a two sublattice antiferromagnet

1 We investigate the dynamics of solitons in two sublattice antiferromagnets 2 under external perturbations, focusing on the effect of Dzyaloshinsky-Moriya 3 (DM) interactions. To this end, we

Relaxation Process in Ferromagnetism

This paper surveys current theoretical work on spin-spin and spin-lattice relaxation in ferromagnetic substances with reference to ferromagnetic resonance. It is shown that it is possible to give a

An Introduction to Effective Field Theories

These notes are an overview of effective field theory (EFT) methods. I discuss toy model EFTs, chiral perturbation theory, Fermi liquid theory, and non-relativistic QED, and use these examples to

Gapped Goldstones at the cut-off scale: a non-relativistic EFT

Abstract At finite density, the spontaneous breakdown of an internal non-Abelian symmetry dictates, along with gapless modes, modes whose gap is fixed by the algebra and proportional to the chemical

Solidity without inhomogeneity: perfectly homogeneous, weakly coupled, UV-complete solids

Solid-like behavior at low energies and long distances is usually associated with the spontaneous breaking of spatial translations at microscopic scales, as in the case of a lattice of atoms. We

Angular momentum conservation and phonon spin in magnetic insulators

We develop a microscopic theory of spin-lattice interactions in magnetic insulators, separating rigid-body rotations and the internal angular momentum, or spin, of the phonons, while conserving the
