WebJan 1, 2024 · The spin entanglement, spin squeezing, and phonon transduction have been carried out by coupling phonon to artificial dopants mechanically or electromagnetically, such as the NV center [17][18][19]. Web2 days ago · Phonon-Induced Collective Modes in Spin-Orbit Coupled Polar Metals. We study the interplay between collective electronic and lattice modes in polar metals in an applied magnetic field aligned with the polar axis. Static spin-orbit coupling leads to the appearance of a particle-hole spin-flip continuum that is gapped at low energies in a finite ... edgar prasthofer

WebIt says that spin s describes the symmetry property of a particle. Basically, the number of different wavefunctions which are transformed into linear combination of one another is 2 … In physics, a phonon is a collective excitation in a periodic, elastic arrangement of atoms or molecules in condensed matter, specifically in solids and some liquids. A type of quasiparticle, a phonon is an excited state in the quantum mechanical quantization of the modes of vibrations for elastic structures of … See more A phonon is the quantum mechanical description of an elementary vibrational motion in which a lattice of atoms or molecules uniformly oscillates at a single frequency. In classical mechanics this designates a See more The equations in this section do not use axioms of quantum mechanics but instead use relations for which there exists a direct correspondence in classical mechanics. See more By analogy to photons and matter waves, phonons have been treated with wavevector k as though it has a momentum ħk; however, this is not strictly correct, because ħk … See more The phonon Hamiltonian is given by $${\displaystyle {\mathcal {H}}={\tfrac {1}{2}}\sum _{\alpha }\left(p_{\alpha }^{2}+\omega _{\alpha }^{2}q_{\alpha }^{2}-\hbar \omega _{\alpha }\right)}$$ In terms of the creation and annihilation operators, … See more Solids with more than one atom in the smallest unit cell exhibit two types of phonons: acoustic phonons and optical phonons. Acoustic phonons … See more The thermodynamic properties of a solid are directly related to its phonon structure. The entire set of all possible phonons that are described by the phonon dispersion relations combine in what is known as the phonon density of states which determines the See more As well as photons, phonons can interact via parametric down conversion and form squeezed coherent states.
