Decaying dark matter in dwarf spheroidal galaxies: Prospects for X-ray and gamma-ray telescopes
Shin'ichiro Ando, Suvendu K. Barik, Zhuoran Feng +12
Dwarf spheroidal galaxies are dark matter dominated systems, and as such, ideal for indirect dark matter searches. If dark matter decays into high-energy photons in the dwarf galax…
Ellipticity-dependent sequential over-barrier ionization of cold rubidium
Junyang Yuan, Shiwei Liu, Xincheng Wang +10
We perform high-resolution measurements of momentum distribution on Rb recoil ions up to charge state , where laser-cooled rubidium atoms are ionized by femtosecond ell…
Momentum spectroscopy for multiple ionization of cold rubidium in the elliptically polarized laser field
Junyang Yuan, Yixuan Ma, Renyuan Li +8
Employing recent developed magneto-optical trap recoil ion momentum spectroscopy (MOTRIMS) combining cold atom, strong laser pulse, and ultrafast technologies, we study momentum di…
Enhanced Light-Matter Interactions in Dielectric Nanostructures via Machine Learning Approach
Lei Xu, Mohsen Rahmani, Yixuan Ma +9
A key concept underlying the specific functionalities of metasurfaces, i.e. arrays of subwavelength nanoparticles, is the use of constituent components to shape the wavefront of th…
Recoil-ion momentum spectroscopy of photoionization of cold rubidium atoms in a strong laser field
Renyuan Li, Junyang Yuan, Xinya Hou +11
We study photoionization of cold rubidium atoms in a strong infrared laser field using a magneto-optical trap (MOT) recoil ion momentum spectrometer. Three types of cold rubidium t…
