Photon-assisted Landau-Zener transitions in a periodically driven Rabi dimer coupled to a dissipative mode
Fulu Zheng, Yuejun Shen, Kewei Sun +1
We investigate multiple photon-assisted Landau-Zener (LZ) transitions in a hybrid circuit quantum electrodynamics device in which each of two interacting transmission-line resonato…
Silabenzene Incorporated Covalent Organic Frameworks
Kewei Sun, Orlando J. Silveira, Yujing Ma +6
Covalent organic frameworks (COFs) are a promising material for various applications such as gas storage/separation, catalysis, and energy storage, besides offering a confined spac…
Excitonic energy transfer in light-harvesting complexes in purple bacteria
Jun Ye, Kewei Sun, Yang Zhao +3
Two distinct approaches, the Frenkel-Dirac time-dependent variation and the Haken-Strobl model, are adopted to study energy transfer dynamics in single-ring and double-ring light-h…
Finite-Temperature Hole-Magnon Dynamics in an Antiferromagnet
Kaijun Shen, Kewei Sun, Maxim F. Gelin +1
Employing the numerically accurate multiple Davydov Ansatz in combination with the thermo-field dynamics approach, we delve into interplay of the finite-temperature dynamics of hol…
Heisenberg Spin-1/2 Antiferromagnetic Molecular Chains
Kewei Sun, Nan Cao, Orlando J. Silveira +7
Carbon-based nanostructures possessing Ï-electron magnetism have attracted tremendous interest due to their great potential for nano spintronics. In particular, quantum chains wit…
Quantifying non-Markovianity for a chromophore-qubit pair in a super-Ohmic bath
Jing Liu, Kewei Sun, Xiaoguang Wang +1
An approach based on a non-Markovian time-convolutionless polaron master equation is used to probe the quantum dynamics of a chromophore-qubit in a super-Ohmic bath. Utilizing a me…
