Harvesting correlations from vacuum quantum fields in the presence of a reflecting boundary
Zhihong Liu, Jialin Zhang, Hongwei Yu
We explore correlations harvesting by two static detectors locally interacting with vacuum massless scalar fields in the presence of an infinite perfectly reflecting boundary. We s…
Multiple superconducting phases driven by pressure in the topological insulator GeSb4Te7
W. Zhou, B. Li, Y. Shen +7
Tuning superconductivity in topological materials by means of chemical substitution, electrostatic gating, or pressure is thought to be an effective route towards realizing topolog…
Two-mode correlated multiphoton bundle emission
Yi Wang, Fen Zou, Jie-Qiao Liao
The preparation of correlated multiphoton sources is an important research topic in quantum optics and quantum information science. Here, two-mode correlated multiphoton bundle emi…
Direct Characteristic-Function Tomography of the Quantum States of Quantum Fields
Zehua Tian, Jiliang Jing, Jiangfeng Du
Herein, we propose a novel strategy for implementing a direct readout of the symmetric characteristic function of the quantum states of quantum fields without the involvement of id…
Chiral topological metals with multiple types of quasiparticle fermions and large spin Hall effect in the SrGePt family materials
Yi Shen, Yahui Jin, Yongheng Ge +2
We present a prediction of chiral topological metals with several classes of unconventional quasiparticle fermions in a family of SrGePt-type materials in terms of first-principles…
Chaotic motion of scalar particle coupling to Chern-Simons invariant in the stationary axisymmetric Einstein-Maxwell dilaton black hole spacetime
Lina Zhang, Songbai Chen, Qiyuan Pan +1
We investigate the motion of a test scalar particle coupling to the Chern-Simons (CS) invariant in the background of a stationary axisymmetric black hole in the Einstein-Maxwell-Di…
