Observation of magnonic spin-orbit torque in epitaxial Co films
Low field harmonic voltage model
To quantitatively analyze magnonic SOTs, we extended the macro-spin model to describe both the longitudinal and transverse harmonic voltages within the low magnetic field range. Considering an epitaxial FM layer…

The characteristics and polarization effects in AlInGaN barrier GaN MISHEMT with various compositions of group III elements
Lattice matched AlxInyGazN/GaN MISHEMT
The significant advantage of quaternary group III-nitride is that its lattice constant and bandgap energy can be adjusted independently, depending on the molar fractions of group III elements. The lattice…

Numerical solution of nonlinear Schrödinger equation by a hybrid pseudospectral-variational quantum algorithm
This section is composed of three parts. First, we will demonstrate the simulation results with the hybrid algorithm and discuss its suitability and accuracy. Secondly, we will investigate the importance of algorithm parameters, such as the width…

Emergent complexity in the decision-making process of chess players
Global emergents in chess
When a chess player faces a position on the board, they must evaluate it, decide which move is the most advantageous, and execute it. This decision-making process is based on the game’s tactical and strategic…

Design of maglev train driven by reconnection electromagnetic launcher
The plate-type reconnection electromagnetic launching system is the most basic among the reconnection electromagnetic launch systems. Many complex models, such as the multi-wing reconnections electromagnetic launching system and multi-pole moment…

Quantification of trace 227Ac and other radionuclidic impurities in mass-separated 225Ac samples produced at CERN-MEDICIS
Direct nuclear-decay spectrometry of the sample to evaluate decay rates of nuclides in the 227Ac chain was challenging, as any signal was estimated to be below the minimum detectable activity (MDA) due to high background radiation from nuclides…

Pressure induced irreversible phase transformation in an ordered high-entropy alloy
The micrograph of the suction-cast EHEA5 exhibits a well-defined lamellar microstructure characteristic of eutectic systems (Fig. 1). The lamellae, composed of alternating phases, are finely spaced, and uniformly distributed across the field of…
