Here, we note an early investigation of another quasiperiodic one-dimensional quantum system, namely, the Ising model on a transverse applied field, which studied the phase transition occurring in its coupling parameter and related critical indexes [28].

The group of proposed applications is even larger and hosts ideas such as quantum circulators [23][24], Ising model simulators [25], and improved gravity wave detection experiments [8]. All these techniques can be migrated to AFM

• simulations were carried out to compute the effective charge carrier mobility and recombination rate. Firstly, the internal morphology in active layers was generated through a simulated annealing method [27]. In the simulated annealing method, the Ising model is adopted to generate the morphology with desired

• molecule in the centre (pinwheel) can be observed. Most interestingly, this distribution of dim and bright C60, like often observed for disordered R30° structures, is typical for the disordered ground state of frustrated Ising systems on a triangular lattice [31][32][33]. A two-dimensional Ising model can

• (albeit much weaker) inter-chain coupling is present as well. To calculate the coupling interactions we have mapped the DFT energies onto a 1D Ising model: with Si being the spin operator projected along the z-direction and Ji,j being the coupling interactions. Two coupling interactions are taken into
