Nonlinear atomic tunnelling boosted by bright squeezed vacuum
Zhejun Jiang, Shengzhe Pan, Jianqi Chen +12
Nonlinear optical processes, mediated by multiphoton interactions rather than single-photon response, are routinely exploited to enable a range of light-based functionalities in de…
Over-Barrier Ionization Dynamics Studied by Backpropagation
Yongzhe Ma, Qingcao Liu, Hongcheng Ni +1
Tunneling and over-barrier ionization are the primary processes of strong-field ionization of atoms and molecules. While the dynamics of tunneling ionization have been extensively…
eTraj.jl: Trajectory-Based Simulation for Strong-Field Ionization
Mingyu Zhu, Hongcheng Ni, Jian Wu
The dynamics of light-matter interactions in the realm of strong-field ionization has been a focal point and has attracted widespread interest. We present the eTraj.jl program pack…
Attosecond Ionization Time Delays in Strong-Field Physics
Yongzhe Ma, Hongcheng Ni, Jian Wu
Electronic processes within atoms and molecules reside on the timescale of attoseconds. Recent advances in the laser-based pump-probe interrogation techniques have made possible th…
PyStructureFactor: A Python code for the molecular structure factor in tunneling ionization rates
Shanshan Song, Mingyu Zhu, Hongcheng Ni +1
Tunneling ionization is at the core of strong-field and attosecond science. In this paper, we present PyStructureFactor - a general Python code towards the calculation of the struc…
Instantaneous Quasiphoton in Strong-Field Ionization
Yongzhe Ma, Hongcheng Ni, Yang Li +2
Photon is a concept that does not apply at the instantaneous level when light is described by classical electromagnetic fields. Exploiting the dynamical rotational symmetry of circ…
Wave-Packet Surface Propagation for Light-Induced Molecular Dissociation
Shengzhe Pan, Zhaohan Zhang, Chenxi Hu +11
Recent advances in laser technology have enabled tremendous progress in photochemistry, at the heart of which is the breaking and formation of chemical bonds. Such progress has bee…
Ionization Induced by the Ponderomotive Force in Intense and High-Frequency Laser Fields
Mingyu Zhu, Yuxiang Liu, Chunli Wei +2
Atomic stabilization is a universal phenomenon that occurs when atoms interact with intense and high-frequency laser fields. In this work, we systematically study the influence of…
Subcycle resolved strong-field tunneling ionization: Identification of magnetic dipole and electric quadrupole effects
Xiaodan Mao, Hongcheng Ni, Xiaochun Gong +2
Interaction of a strong laser pulse with matter transfers not only energy but also linear momentum of the photons. Recent experimental advances have made it possible to detect the…

We experimentally and theoretically investigate the influence of the magnetic component of an electromagnetic field on high-order above-threshold ionization of xenon atoms driven b…
Quantum Battles in Attoscience -- Tunnelling
Cornelia Hofmann, Alexander Bray, Werner Koch +2
What is the nature of tunnelling? This yet unanswered question is as pertinent today as it was at the dawn of quantum mechanics. This article presents a cross section of current pe…
Theory of Subcycle Linear Momentum Transfer in Strong-Field Tunneling Ionization
Hongcheng Ni, Simon Brennecke, Xiang Gao +8
Interaction of a strong laser pulse with matter transfers not only energy but also linear momentum of the photons. Recent experimental advances have made it possible to detect the…
Polarization tagging of two-photon double ionization by elliptically polarized XUVs
