Momentum mapping of continuum electron wave packet interference
Weifeng Yang, Huatang Zhang, Cheng Lin +5
We analyze the two-dimensional photoelectrons momentum distribution of Ar atom ionized by midinfrared laser pulses and mainly concentrate on the energy range below 2Up. By using a…
Spatiotemporal steering of photoelectron emission in multiphoton above-threshold ionization
Xiaochun Gong, Cheng Lin, Mingming Liu +11
We experimentally demonstrate spatiotemporal steering of photoelectron emission in multiphoton above-threshold single ionization of atoms exposed to a phase-controlled orthogonally…
Cooling a Mechanical Resonator to Quantum Regime by heating it
Yue Ma, Zhang-qi Yin, Pu Huang +2
We consider a mechanical resonator made of diamond, which contains a nitrogen-vacancy center (NV center) locating at the end of the oscillator. A second order magnetic gradient is…
Unraveling nonadiabatic ionization and Coulomb potential effects in strong-field photoelectron holography
Xiaohong Song, Cheng Lin, Zhihao Sheng +6
Strong field photoelectron holography has been proposed as a means for interrogating the spatial and temporal information of electrons and ions in a dynamic system. After ionizatio…
Attosecond Interference Induced by Coulomb-Field-Driven Transverse Backward-Scattering Electron Wave-Packets
Xiaohong Song, Peng Liu, Cheng Lin +9
A novel and universal interference structure is found in the photoelectron momentum distribution of atoms in intense infrared laser field. Theoretical analysis shows that this stru…
