On-chip microwave coherent source with in-situ control of the photon number distribution
Concept and implementation
A schematic of the setup for the implementation of the proposed system is shown in Fig. 1a. The system consists of Nr + 2 elements, where Nr corresponds to the number of elements on the output, here represented as…

Incorporation of model accuracy in gravitational wave Bayesian inference
Estimating waveform accuracy
As discussed in ‘Model systematics in gravitational wave astronomy’, the accuracy of a theoretical GW model is often assessed by comparing the signals produced by the model against numerical relativity simulations….

Predicting mean depth and area fraction of Antarctic supraglacial melt lakes with physics-based parameterizations
Self-affinity of Antarctic surface roughness from ICESat-2
Self-affinity describes a repeating pattern within an object, sequence, or surface that occurs over a wide range of scales (also referred to as “fractal” or “self-similar”) (Fig.

Automated identification of the origin of energy loss in nonoriented electrical steel by feature extended Ginzburg–Landau free energy framework
We analyzed the correlation between the obtained features and magnetic properties to discuss the mechanism of the magnetization reversal process. The PC1 score demonstrated a monotonous increase in magnetization (Fig. 4a). The PC1 score is a…

Pseudo-spin light circuits in nonlinear photonic crystals
Pseudo-spin guiding mechanism
We can describe the process of paraxial SFG process in the undepleted pump approximation using the coupled wave equations, written as an optical pseudo-spin transport equation, while assuming a phase-matched…
