  1. Sep 4, 2024 · The classical Landau-Lifshitz equationthe simplest model of a ferromagnet—provides an archetypal example for studying transport phenomena. In one-spatial dimension, integrability enables the classification of linear and nonlinear mode spectrum.

  2. Sep 5, 2024 · The quantum Hall effect emerges when two-dimensional samples are subjected to strong magnetic fields at low temperatures: Topologically protected edge states cause a quantized Hall conductivity in multiples of . Here we show that the quantum Hall effect is accompanied by an orbital Hall effect.

  3. Sep 12, 2024 · Our simulations of twisted graphene nanoribbons reveal well-defined Landau spectra and sublattice polarization of phonon states, mimicking the behavior of Dirac Fermions in magnetic fields. Both valley-specified helical edge currents and snake orbits are obtained.

  4. Sep 13, 2024 · Here, we report the discovery of the Landau-phonon polaritons (LPPs) in a 2D graphene-hexagonal boron nitride (hBN) heterostructure. The LPPs result from the hybridization (19–21) of phonon polaritons of the hBN encapsulating layers (8–10) with Dirac magnetoexcitons (6, 7) [or “Landau polaritons” ] of charge-neutral graphene (6, 7 ...

  5. Here, we report Landau- phonon polaritons (LPPs) in magne-tized charge- neutral graphene encapsulated in hexagonal boron nitride (hBN). These quasiparticles emerge from the interaction of Dirac magnetoexciton modes in graphene with the hyperbolic phonon polariton modes in hBN.

  6. Sep 13, 2024 · Abstract. One of the necessary conditions for achieving high thermoelectric (TE) performance is the large longitudinal (Sxx) and transverse thermopower (Syx), which are closely related to the Fermi level position and the energy-dependent density of states (DOS) at the Fermi level.

  7. Sep 4, 2024 · The phenomenological LandauLifshitz equation (LL) suggested by Landau and Lifshitz in 1935 to describe the precessional motion of spins in ferromagnetic materials has shown its limitations when the temperature is close to or above the Curie temperature.
