Note on Angular Momentum of Phonons in Chiral Crystals
نویسندگان
چکیده
Phonon angular momentum in chiral materials has been widely studied spintronics and condensed matter physics. In crystals, this is not the conserved quantity contrast to pseudo-angular momentum. To highlight point understand behavior of momentum, we reexamined phonon dispersion theory based on irreducible representation helix found distinction these originated from chirality.

Orbital Angular Momentum in Chiral Quark Model
We developed a new and unified scheme for describing both quark spin and orbital angular momenta in symmetry-breaking chiral quark model. The loss of quark spin in the chiral splitting processes is compensated by the gain of the orbital angular momentum carried by quarks and antiquarks. The sum of both spin and orbital angular momenta carried by quarks and antiquarks is 1/2. The analytic and nu...
متن کاملPhotons, phonons, and plasmons with orbital angular momentum in plasmas
Exact eigen modes with orbital angular momentum (OAM) in the complex media of unmagnetized homogeneous plasmas are studied. Three exact eigen modes with OAM are derived, i.e., photons, phonons, and plasmons. The OAM of different plasma components are closely related to the charge polarities. For photons, the OAM of electrons and ions are of the same magnitude but opposite direction, and the tot...
متن کاملChiral orbital-angular momentum in the surface states of Bi2Se3.
We performed angle-resolved photoemission (ARPES) experiments with circularly polarized light and first-principles density functional calculation with spin-orbit coupling to study surface states of a topological insulator Bi2Se3. We observed circular dichroism (CD) as large as 30% in the ARPES data with upper and lower Dirac cones showing opposite signs in CD. The observed CD is attributed to t...
متن کاملAngular momentum-induced circular dichroism in non-chiral nanostructures.
Circular dichroism, that is, the differential absorption of a system to left and right circularly polarized light, is one of the only techniques capable of providing morphological information of certain samples. In biology, for instance, circular dichroism spectroscopy is widely used to study the structure of proteins. More recently, it has also been used to characterize metamaterials and plasm...
متن کاملOrbital Angular Momentum in the Chiral Quark Model
Analytical and numerical results, for the orbital and spin content carried by different quark flavors in the baryons, are given in the chiral quark model with symmetry breaking. The reduction of the quark spin, due to the spin dilution in the chiral splitting processes, is transferred into the orbital motion of quarks and antiquarks. The orbital angular momentum for each quark flavor in the pro...
