No spin-localization phase transition in the spin-boson model without local field
Tao Liu, Mang Feng, Lei Li +2
We explore the spin-boson model in a special case, i.e., with zero local field. In contrast to previous studies, we find no possibility for quantum phase transition (QPT) happening…
Quantum-memory-assisted entropic uncertainty principle under noise
Z. Y. Xu, W. L. Yang, M. Feng
The measurement outcomes of two incompatible observables on a particle can be precisely predicted when it is maximally entangled with a quantum memory, as quantified recently [Natu…
Dissipative dynamics of quantum discord under quantum chaotic environment
Y. Y. Xu, W. L. Yang, M. Feng
We investigate the dissipative dynamics of quantum discord in a decoherence model with two initially entangled qubits in addition to a quantum kicked top. The two qubits are uncoup…
Comparison of different measures for quantum discord under non-Markovian noise
Zhenyu Xu, Wanli Yang, Xing Xiao +1
Two geometric measures for quantum discord were recently proposed by Modi et al. [Phys. Rev. Lett. 104, 080501 (2010)] and Dakic et al. [Phys. Rev. Lett. 105, 190502 (2010)]. We st…
Franck-Condon Physics in A Single Trapped Ion
Y. M. Hu, W. L. Yang, Y. Y. Xu +5
We propose how to explore the Franck-Condon (FC) physics via a single ion confined in a spin-dependent potential, formed by the combination of a Paul trap and a magnetic field grad…
Proposed method for direct measurement of non-Markovian character of the qubits coupled to bosonic reservoirs
Z. Y. Xu, W. L. Yang, M. Feng
The non-Markovianity is a recently proposed characterization of the non-Markovian behavior in an open quantum system, based on which we first present a practical idea for directly…
