Searching for axion-like particles with space-based optical lattice clock networks
Yu-Song Cao, Nick Houston, YanXia Liu +2
Axion like particles (ALPs) are particularly well motivated candidates for dark matter, and physics beyond the Standard Model more generally. However, direct detection remains extr…
Laser-induced selection of longitudinal bosons in resonant annihilation
Fengye Chen, Qingzheng Lv, Libin Fu
Longitudinal \(Z\)-boson production is strongly suppressed in collinear \(e^+e^-\) annihilation in vacuum due to current conservation and helicity selection. We show that this supp…
Symmetry-Breaking Electron Dynamics Enable Ultrabroadband Optical-Field Sampling via Second-Harmonic Generation
Wenqi Tang, Ahai Chen, Michael Klaiber +4
Optical-field sampling using second-harmonic generation (SHG) from strong-field ionization enables ultrabroadband terahertz detection, but the microscopic origin of the SHG signal…
Low-energy photoelectron structures for arbitrary ellipticity of a strong laser field
Q. Z. Lv, M. Klaiber, P. -L. He +2
Previous attoclock experiments measuring the photoelectron momentum distribution (PMD) via strong-field ionization in an elliptically polarized laser field have shown anomalously l…
