Proposal for a topological plasmon spin rectifier
... spin accumulation in the NM, we propose to detect nonzero ⌬Sy with ferromagnetic tunnel voltage probes.7 To rule out spurious signals due to asymmetric tunnel barriers and current rectification/photovoltaic effects across the contacts, a magnetic field Bz perpendicular to the surface 共in the ẑ dire ...

Quantized conductance in magnetic field: spin resolved plateaus
... at zero magnetic field evolves towards the spin resolved plateaux, a signature of the spin nature of this particular feature. If one extracts the transconductance (the derivative of the conductance with respect to the gate voltage as seen in figure 4 b), it is clear that the distance between the first ...

MODULE MAPS OVER LOCALLY COMPACT QUANTUM GROUPS
... M (C0 (G)). This is a quite general result, which covers all Kac algebras, though we still do not know whether it holds for all quantum groups. See [56, 58] for some co-amenable cases, where LU C(G) was also shown to be a C ∗ -algebra. Let W AP (G) be the space of weakly almost periodic functionals ...

Spin Foam Models for Quantum Gravity
... According to the (background dependent) perspective of standard QFT [2], non renormalizability signals the inconsistency of the theory at high energies to be corrected by a more fundamental theory in the UV regime. A classical example of this is Fermi’s fourfermion theory as an effective description ...

Topological insulator with time
... † Seems that the spin-orbit coupling can give us TIs without breaking the time-reversal symmetry, but there are two things one needs to notice (which are the key discoveries Kane and Mele made): 1. The edge states are only protected in the presence of the time-reversal symmetry. If we break the time ...
