SPIN WAVES ALONG THE EDGE STATES

Spin Waves along the Edge States

Spin waves (SWs) have been studied experimentally and by simulations in 1000 nm side equilateral triangular Permalloy dots in the Buckle state (B, with in-plane ̄eld along the triangle base) and the Y state (Y, with in-plane ̄eld perpendicular to the base). The excess of exchange energy at the triangles edges creates channels that allow e®ective spin wave propagation along the edges in the B stat...

Edge waves along a sloping beach

Standing on a gently sloping straight beach, it is a matter of observation that various waveforms propagate on the surface of the sea. Among these we find edge waves water waves that progress along the shoreline. These waves, often difficult to visualize (this has, probably, prevented the regarding of this waveform as important for a long time), are coastal trapped, i.e. their amplitude is maxi...

Observation of propagating edge spin waves modes

investigation of high-spin rotational states in the atomic nucleus.

the ground state rotational bands of some rare earth nuclei show a rather strange behaviour at large values of angular momenta. the nuclear moment of inertia teta increases smoothly with angular momentum i up to i=12. then at about i=14 there is a sudden increase in the moment of inertia. the plot of teta versus the square of the angular velocity w gives a s-shaped curve. we attempt here to rep...

Tunneling between edge states in a quantum spin Hall system.

We analyze a quantum spin Hall device with a point contact connecting two of its edges. The contact supports a net spin tunneling current that can be probed experimentally via a two-terminal resistance measurement. We find that the low-bias tunneling current and the differential conductance exhibit scaling with voltage and temperature that depend nonlinearly on the strength of the electron-elec...
