Note on searching for critical lattice models as entropy critical points from strange correlator
Anran Jin, Ling-Yan Hung
An entropy function is proposed in [Phys. Rev. Lett. 131, 251602] as a way to detect criticality even when the system size is small. In this note we apply this strategy in the sear…

Breather interactions and limit analysis in the second harmonic generation process via Riemann-Hilbert approach
An-Yao Jin, Rui Guo
The discovery of second harmonic generation (SHG) heralds the emergence of nonlinear optics. In this paper, we focus on the theoretical analysis of the SHG equation under phase-mat…

Pilot-reference-free continuous-variable quantum key distribution with efficient decoy-state analysis
Anran Jin, Xingjian Zhang, Liang Jiang +2
Continuous-variable quantum key distribution (CV QKD) using optical coherent detectors is practically favorable due to its low implementation cost, flexibility of wavelength divisi…
