Doppler-free selective reflection spectroscopy of electric-quadrupole transitions
Eng Aik Chan, Syed Abdullah Aljunid, Athanasios Laliotis +2
Electric-dipole-forbidden transitions play an important role as in quantum sensing, quantum information, and fundamental test in physics. As such, the development of novel and sens…

Dirac mass induced by optical gain and loss
Letian Yu, Haoran Xue, Ruixiang Guo +5
Mass is commonly regarded as an intrinsic property of matter, but modern physics reveals particle masses to have complex origins, such as the Higgs mechanism in high-energy physics…

Retrieving positions of closely packed sub-wavelength nanoparticles from their diffraction patterns
Benquan Wang, Ruyi An, Eng Aik Chan +6
Distinguishing two objects or point sources located closer than the Rayleigh distance is impossible in conventional microscopy. Understandably, the task becomes increasingly harder…
