Conical Intersections Enable Ultrafast Molecular Spin Control in a Chromium Complex
Zihui Liu, Junhua Zhou, Tianrui Chen +8
Molecular spintronics seeks to control spin states in single molecules for ultrafast switching and efficient information processing. Transition metal complexes are promising candid…
Quantum Dynamics of Enantiomers in Chiral Optical Cavities
Yang-Cheng Ye, Panpan Zhang, Ajay Jha +2
Chirality, the absence of mirror symmetry, is a fundamental molecular property with far-reaching consequences from chemistry to biology. Yet enantiosensitive optical responses are…
Controlling Nonadiabatic Transitions Through Engineered Ultrafast Laser Fields at Conical Intersections
Xuanchao Zhang, Yang-Cheng Ye, Panpan Zhang +5
In this paper, we investigate coherent control of nonadiabatic dynamics at a conical intersection (CI) using engineered ultrafast laser pulses. Within a model vibronic system, we t…
Unraveling Geometric-phase at Conical Intersection by Cavity-enhanced Two-dimensional Electronic Spectroscopy
Yang-Cheng Ye, Fulu Zheng, Ajay Jha +1
The geometric phase is a fundamental quantum mechanical phenomenon uniquely associated with conical intersections (CI) between potential energy surfaces and serves as a definitive…
Excitonic Energy Transfer in Red Algal Photosystem I Reveals an Evolutionary Bridge between Cyanobacteria and Plants
Mengyuan Cui, Zihui Liu, Miriam Izzo +9
Photosystem I converts light into chemical energy with near-unity quantum efficiency,yet its energy-transfer and charge-separation mechanisms remain debated. Evolution has diversif…
Low-Noise Nanoscale Vortex Sensor for Out-of-Plane Magnetic Field Detection
Ajay Jha, Alvaro Palomino, Stéphane Auffret +4
This study investigates a vortex sensor based on a nanoscale (sub-100 nm) magnetic tunnel junction (MTJ) with a strong shape anisotropy, designed for sensitivity to the out-of-plan…
