Dynamics of a driven spin coupled to an antiferromagnetic spin bath
Xiao-Zhong Yuan, Hsi-Sheng Goan, Ka-Di Zhu
We study the behavior of the Rabi oscillations of a driven central spin (qubit) coupled to an antiferromagnetic spin bath (environment). It is found that the decoherence behavior o…
Geometric phase of a central spin coupled to an antiferromagnetic environment
Xiao-Zhong Yuan, Hsi-Sheng Goan, Ka-Di Zhu
Using the spin-wave approximation, we study the geometric phase (GP) of a central spin (signal qubit) coupled to an antiferromagnetic (AF) environment under the application of an e…
Nanomechanical-resonator-assisted induced transparency in a Cooper-pair-box system
Xiao-Zhong Yuan, Hsi-Sheng Goan, Chien-Hung Lin +2
We propose a scheme to demonstrate the electromagnetically induced transparency (EIT) in a system of a superconducting Cooper-pair box coupled to a nanomechanical resonator. In thi…
Influence of an external magnetic field on the decoherence of a central spin coupled to an antiferromagnetic environment
Xiao-Zhong Yuan, Hsi-Sheng Goan, Ka-Di Zhu
Using the spin wave approximation, we study the decoherence dynamics of a central spin coupled to an antiferromagnetic environment under the application of an external global magne…
Non-Markovian reduced dynamics and entanglement evolution of two coupled spins in a quantum spin environment
Xiao-Zhong Yuan, Hsi-Sheng Goan, Ka-Di Zhu
The exact quantum dynamics of the reduced density matrix of two coupled spin qubits in a quantum Heisenberg XY spin star environment in the thermodynamic limit at arbitrarily finit…
Charge qubit dynamics in a double quantum dot coupled to phonons
Zhuo-Jie Wu, Ka-Di Zhu, Xiao-Zhong Yuan +2
The dynamics of charge qubit in a double quantum dot coupled to phonons is investigated theoretically in terms of a perturbation treatment based on a unitary transformation. The dy…
