The utility model provides a three -dimensional projection arrangement of DLP polarisation formula, includes white light light source, beam shaping system, DMD chip, projecting lens, beam split / close and be bare prism group and drive signal the control unit, wherein beam split / close light ...
Owing to the limited spatio-temporal resolution of display devices, dynamic holographic three-dimensional displays suffer from a critical trade-off between the display size and the visual angle. Here we show a projection-type holographic three-dimensiona
To begin, we consider a 2D spinful (fermionic), noninteracting insulator lying in the xy-plane with s = sz spin-rotation symmetry (i.e., U(1) spin symmetry, in addition to the U(1) charge conservation symmetry65). We emphasize that the simultaneous requirements of charge and sz s...
where the indices j = i + 1 (mod 3) and k = i + 2 (mod 3) refer to the cyclic ordering of edges of f, ⊗ denotes the outer product, t-i is the result of clockwise rotating edge ēi by π/2 in the plane of Tf, and āf=|T-f| is the area of f. Notice that Af has...
ρ2(x) two-dimensional function in the space of a two-dimensional vector x, x = x(x, y), x = (r, ψ); ρ2(xτ) projection of function ρ3 along the unitary vector τ(|t| = 1) onto the plane x⊥ t; ρ1(x) one-dimensional function; ρ1(xψ) = L(xψ), one-dimensio...
The spaces of harmonic maps of the projective plane to the four-dimensional sphere are investigated in this paper by means of twistor lifts. It is shown that such spaces are empty in case of even harmonic degree. In case of harmonic degree less than 6 it was shown that such spaces are ...
Let S1 denote the unit circle of the complex plane C. Given any n ∈ Z, consider the self-map σn of S1 defined by z → zn. It is well known, and easy to check, that the winding number (or, equivalently, the Brouwer degree) of this self-map is n. If n < 0, the function...

A high in-plane mobility of 4.9 cm2V−1s −1 is observed when the THz electric field oscillates fully along the LDP planes, for the horizontal samples. For the vertical sample, on the other hand, the E-field vector lies on average half along the LDP planes, and half in the ...
