Mean chiral displacement
Webthe mean chiral displacement of the bulk dynamics can be used to reveal the topological phases, which can al-ready be implemented in ultracold atomic and photonic systems [26,76{84]. Finally, we discuss the TAI phase in a more general case with both binary disordered inter-and intra-cell hoppings. The rest of this paper is organized as follows. We WebThe analytical results of the sphere submitted to a 1 V harmonic excitation, 2000 V/m electric field, has been compared with the numerical results. Figures 13.46 to 13.48, …

(2) In the above, c† x,τ,s is the creation operator of a fermionic particle (with sublattice index τ and spin s acting on the Web“Working with Taylor,” Gadway adds, “our Spanish colleagues found that the mean chiral displacement is essentially equivalent to the topological invariant of such a 1-D system, something called the winding number. This was critical to our being able to take the data on the system and relate what we saw in experiment to the system’s ...
