Decoherence of Dirac-particle quantumness for fermionic fields in a dilatonic black hole
Chengjun Yao, Yating Shao, Kai Yan +2
The quantumness of Dirac paticles for quantized fields in a dilatonic black hole is estimated by means of quantum channel. We develop a general Bloch vector representation of quant…
Phase diagram of the spin-1/2 Heisenberg alternating chain in a magnetic field
Wei-Xia Chen, Jie Ren, Wen-Long You +2
By using the infinite time-evolving block decimation, we study quantum fidelity and entanglement entropy in the spin-1/2 Heisenberg alternating chain under an external magnetic fie…
Quantum Parameter Estimation in the Unruh-DeWitt detector model
Xiang Hao, Yinzhong Wu
Relativistic effects on the precision of quantum metrology for particle detectors, such as two-level atoms are studied. The quantum Fisher information is used to estimate the phase…
Thermal Quantum Speed Limit for Classical-Driving Open Systems
Wenjiong Wu, Kai Yan, Xiang Hao
Quantum speed limit (QSL) time for open systems driven by classical fields is studied in the presence of thermal bosonic environments. The decoherence process is quantitatively des…
Expansion dynamics in a one-dimensional hard-core boson model with three-body interactions
Jie Ren, Yin-Zhong Wu, Xue-Fen Xu
Using the adaptive time-dependent density matrix renormalization group method, we numerically investigate the expansion dynamics of bosons in a one-dimensional hard-core boson mode…
Quantum discord and entanglement in Heisenberg XXZ spin chain after quenches
Jie Ren, Yin-Zhong Wu, Shi-Qun Zhu
Using the adaptive time-dependent density-matrix renormalization group method, the dynamics of entanglement and quantum discord of a one-dimensional spin-1/2 XXZ chain is studied w…
