A Route to Nonrelativistic Altermagnetic Spin Splitting via Ultrafast Light
Huang-Zhao-Xiang Chen, Lin-Ding Yuan, Wen-Hao Liu +3
We identify a nonequilibrium route for generating altermagnetic spin splitting in antiferromagnet by ultrafast light. Unlike existing strategies, this route does not require relati…
Enhancing Cutoff Energy of Solid High-Harmonic Generation from Bonding Length Perspective
Qing-Guo Fan, Kang Lai, Wen-hao Liu +3
High-harmonic generation (HHG) from solid state offers promising potential for attosecond optics with enhanced efficiency and compact configurations. However, Current implementatio…
Revealing Material-Dependent Bicircular High-Order Harmonic Generation in 2D Semiconductors via Real-Space Trajectories
Qing-Guo Fan, Kang Lai, Wen-hao Liu +3
Solid-state high-order harmonic generation (HHG) presents unique features different from gases.Whereas the gaseous harmonics driven by counter-rotating bicircular (CRB) pulse unive…
Occupation-Driven emission asynchronous as a Fundamental Constraint on Solid-State Attosecond Pulses
Qing-Guo Fan, Kang Lai, Wen-hao Liu +3
A newly analytic occupation-resolved theory capturing the temporal structure of attosecond pulses (APs) is derived. We validate it with real-time time-dependent density functional…
Ultrafast dynamics of atomic correlated disordering in photoinduced VO
Wen-Hao Liu, Feng-Wu Guo, Lin-Wang Wang +1
Recent experiments suggest that atomic disordering dynamics are more universal than conventional coherent processes in photoinduced phase transitions (PIPTs), yet its mechanism rem…
Tailoring light holes in - via Anion-Anion Antibonding Coupling
Ke Xu, Qiaolin Yang, Wenhao Liu +3
A significant limitation of wide-bandgap materials is their low hole mobility related to localized holes with heavy effective masses (). We identify in low-symmetric wide-ba…

Feng-Wu Guo, Wen-Hao Liu, Zhi Wang +3
The insulator-to-metal transition (IMT) in vanadium dioxide (VO2) has garnered extensive attention for its potential applications in ultrafast switches, neuronal network architectu…
Origin of Immediate Damping of Coherent Oscillations in Photoinduced Charge Density Wave Transition
Yu-Xiang Gu§, Wen-Hao Liu§, Zhi Wang +3
In stark contrast to the conventional charge density wave (CDW) materials, the one-dimensional CDW on the In/Si(111) surface exhibits immediate damping of the CDW oscillation durin…
Photoinduced charge density wave transition like a puppet on a string
Zhao-Jun Suo, Wen-Hao Liu, Zhi Wang +4
Charge density wave (CDW) materials can undergo an ultrafast phase transition after an ultrashort laser pulse excitation, and the suggested underlying mechanisms have always been a…
Uniting the order and disorder dynamics in photoexcited VO2
Hao-Wen Liu, Wen-Hao Liu, Zhao-Jun Suo +4
Photoinduced phase transition (PIPT) is always treated as a coherent process, but ultrafast disordering in PIPT is observed in recent experiments. Utilizing the real-time time-depe…
Dynamic short-range correlation in photoinduced disorder phase transitions

Wen-Hao Liu, Jun-Wei Luo*, Shu-Shen Li +1
Laser-induced nonthermal melting in semiconductors has been studied over the last four decades, but the underlying mechanism is still under debate. Here, by utilizing an advanced r…
The critical role of hot carrier cooling in optically excited structural transitions
Wen-Hao Liu, Jun-Wei Luo, Shu-Shen Li +1
The hot carrier cooling occurs in most photoexcitation-induced phase transitions (PIPTs), but its role has often been neglected in many theoretical simulations as well as in propos…
