Floquet Nonadiabatic Dynamics for Light-Matter Interactions: Recent Advances and Emerging Opportunities
Jiayue Han, Yu Wang, Vahid Mosallanejad +2
Light-matter interactions provide versatile routes for probing and controlling chemical reactivity, charge transport, and material properties. Time-periodic external fields can res…
Multi-mode Floquet NEGF method for driven quantum transport
Vahid Mosallanejad, Wenjie Dou
We present a non-perturbative Floquet-based non-equilibrium Green's function (NEGF) method to study electron transport in a quantum system driven simultaneously by multiple indepen…
Two-Mode Floquet Fewest Switches Surface Hopping for Nonadiabatic Dynamics Driven by Two-Frequency Laser Fields
Jiayue Han, Vahid Mosallanejad, Ruihao Bi +1
Two-frequency (two-color) laser fields provide a powerful and flexible means for steering molecular dynamics. However, quantitatively reliable and scalable theoretical tools for si…
Two-mode Floquet Redfield quantum master approach for quantum transport
Vahid Mosallanejad, Wenjie Dou
Simultaneous driving by two periodic oscillations yields a practical technique for further engineering quantum systems. For quantum transport through mesoscopic systems driven by t…
The cell-centered Finite-Volume self-consistent approach for heterostructures: 1D electron gas at the Si-SiO2 interface
Vahid Mosallanejad, Haiou Li, Gang Cao +3
Achieving self-consistent convergence with the conventional effective-mass approach at ultra-low temperatures (below ) is a challenging task, which mostly lies in the discon…
Space-averaged non-equilibrium Green's function approach for quantum transport in 3D
Vahid Mosallanejad, Kuei-Lin Chiu, Wenjie Dou
The non-equilibrium Green's function (NEGF) approach offers a practical framework for simulating various phenomena in mesoscopic systems. As the dimension of electronic devices shr…
