Reconstructing shock front of unstable detonations based on multi-layer perceptron
Lin Zhou, Honghui Teng, Hoi Dick Ng +2
The dynamics of frontal and transverse shocks in gaseous detonation waves is a complex phenomenon bringing many difficulties to both numerical and experimental research. Advanced l…
High-numerical-aperture and long-working-distance objectives for single-atom experiments
Shaokang Li, Gang Li, Wei Wu +5
We present two long-working-distance objective lenses with numerical apertures (NA) of 0.29 and 0.4 for single-atom experiments. The objective lenses are assembled entirely by the…
Realization of nonlinear optical nonreciprocity on a few-photon level based on atoms strongly coupled to an asymmetric cavity
Pengfei Yang, Xiuwen Xia, Hai He +8
Optical nonreciprocity is important in photonic information processing to route the optical signal or prevent the reverse flow of noise. By adopting the strong nonlinearity associa…
A general criterion for solid instability and its application to creases
Pengfei Yang, Yaopeng Fang, Yanan Yuan +4
A general force-perturbation-based criterion for solid instability is proposed, which can predict instability including crease without priori knowledge of instability configuration…
