Subtraction logic for negative weights

Let the parallel (P) and anti-parallel (AP) MTJ conductances be denoted by G_P and G_AP, respectively, within an MTJ crossbar array G. Let v_in be a binarized input voltage vector with values 0 and a fixed…

The schematic cross-sectional view of the double BHJ OPD, comprising a layer configuration of glass/ITO/ZnO (10 nm)/PM6:IT-4F (1:1) (3.5 µm)/MoO₃ (5 nm)/PTB7-Th:COTIC-4Cl:Y6 (1:1.05:0.45) (670 nm)/ZnO (10 nm)/Ag, is shown in Fig. 1a….

Li_xMn_1−yFe_yPO₄ (0 < x ≤ 1, 0 ≤ y ≤ 1), which crystallizes in the Pnma space group^29,30, can exhibit three distinct Mn and Fe distributions within the unit cell when the Mn: Fe ratio is 1:1, as shown in Fig. 1. The first…

Statistical analysis revealed significant heterogeneity in transmission patterns across different waves of the pandemic. For instance, during the first wave, the majority of infected individuals were elderly (70 years and above) especially in…

In this section, we describe the LR-QAOA, some properties of LR-QAOA, the combinatorial optimization problems used, the classical solvers used to compare scaling properties, and experimental details on real quantum hardware.

LR-QAOA

QAOA consists…

Ground states of CrI₂ monolayer

We specifically derive the U value from the monolayer structure, which is relevant to our study. On-site Coulomb interaction to the Cr d orbitals was calculated using the linear response method³⁰. We calculate the…

Classical computational chemistry

Initially, the minimum-energy path of the VC + \(^1\)O\(_2\) \(\rightarrow\) dioxetane reaction is determined with the nudged elastic band (NEB) method, using PySCF and Jónsson’s group implementation of NEB³⁴…

To solve the system (10)–(12) using egendre-collocation technique³⁵, the solution domain should transformed from \([0,{L}_{\eta }]\) or \([0,{L}_{\xi }]\) to the interval \([-{1,1}]\). Hence, the linear transformations \(\eta…
