Vertical interaction parameters for 2 × 4 depend on the parity of the row index. Grey circles denote the unused qubits on the 23-qubit Rainbow chip. Full size image We studied Fermi-Hubbard model instances on lattices of shapes 1 × Ly and 2 × Ly. A 1 × Ly Fermi...
Parity (P) The P Operator (P), works on x, p, L, S. P reverses the components of all true vectors. For example, the parity operation on radius and momentum vectors produces: Note that angular momentum is the product of two vectors so it does not get reversed by the parity operator...
channel can be an ideal channel to extract the spin-parity quantum numbers of the \(p_c(4440)\) and \(p_c(4457)\) . thirdly, we compare the \(\bar{d} \varsigma _c\) and \(j/\psi p\) channels: $$\begin{aligned}&{{\mathcal {b}}\left( |\bar{d}^* \varsigma _c; ...
To this end, the excitation of uncharged and massless scalar fields is going to be determined by the Klein–Gordon equation: = 0, (27) where denotes the D'Alembert operator. So, Eq. (27) can be rewritten as √1−g ∂μ(√−ggμν∂ν ) = 0, (28) in which for our D-...
Thus, according to the symmetry classification, such a system belongs to the BDI class since the square of the time-reversal operator and the square of the sublattice symmetry operator equal to 1. In general, the topological index of the one dimensional system Z-index can be defined by two...
