Photon-accelerated vector vortex beams
In a photon accelerator, a moving refractive index gradient alters the local phase velocity of a light wave. If the light wave co-travels with a negative (positive) refractive index gradient in a normally…

Investigation of flow-induced noise reduction in high-specific-speed centrifugal pumps using bionic blades
Hydraulic performance verification
The external characteristic curve obtained from the test and simulation is shown in Fig. 8. The flow field and sound field calculations were completed based on the rated working conditions. In the figure, Qd is…

Modelling optomechanical responses in optical tweezers beyond paraxial limits
Experimental setup
The schematic of our experimental setup is illustrated in Fig. 1. The setup includes an iris diaphragm positioned at the pupil plane to control the focusing NA of the trapping light [Fig. 1(a)]. Specifically, a continuous-wave…

Observation of ferromagnetic phase in the second moiré band of twisted MoTe2
Device structure and characterization
The tMoTe2 device is fabricated into dual gate structures as shown in Fig. 1a. We adopt similar tear and stack method9,10,11 to fabricate tMoTe2 as used in previous work9,10. Figure 1b shows the schematic…
