摘要:\((u,v)\)]]> -flowers called Xq -flowers, which have both fractal (or pseudofractal) and scale-free characteristics. Using the tool of probability generating function, we calculate the first and second moments of the first-passage time (FPT), the first return time (FRT...

摘要:We proposed a general method for efficiently recording trajectories of states for analyzing the time correlation functions (TCFs) A ( t ) of arbitrary quantities from short to long times, for computer simulations, to reproduce dynamic behaviors. If the quantities for TCF are...

摘要:Motivated by the recent progress of phonon-mediated control in quantum spin devices, we propose a possibility of hybrid measurement using electron paramagnetic resonance (EPR) and a surface acoustic wave (SAW). Considering quadrupole-strain (QS) couplings suggested for silicon va...

摘要:Applications of neural networks to condensed matter physics are becoming popular and beginning to be well accepted. Obtaining and representing the ground and excited state wave functions are examples of such applications. Another application is analyzing the wave functions a...

摘要:We newly propose a methodology to extract and model the effect of small-scale on large-scale fluctuations, for applications to disparate-scale turbulence problem having energy injections not only at large but also at small scales. For this purpose, we applied the Mori–Zwanzi...

摘要:Novel ternary Laves phase compounds were explored, and Mg2Ir3Si was synthesized via a solid-state reaction. X-ray diffraction studies revealed that Mg2Ir3Si crystallizes in a Mg2Cu3Si-type structure ( P 63...

摘要:Hierarchical equations of motion approach with the Drude–Lorentz spectral density has been widely employed in investigating quantum dissipative phenomena. However, it is often computationally costly for low-temperature systems because a number of Matsubara frequencies are in...

摘要:We have succeeded in synthesizing electron-doped polycrystalline bulk samples of T′-La1.8Eu0.2CuO4− y F y ( y = 0–0.15) by the fluorination of undoped (Ce-free) T′-La1.8Eu0.2CuO4 usi...

摘要:We investigate the stability of multiple- Q spiral states in d – p electron systems with the strong spin–charge coupling. By using variational calculations on a square lattice, we find that the double- Q state with the scalar chirality density wave, which has been studied in...
