The analogy of the Lorentz-violating fermion-gravity and fermion photon couplings
Cheng Ye, Zhi Xiao
By adopting a methodology proposed by R.J. Adler \etl, we study the interesting analogy between the fermion-gravity and the fermion-electromagnetic interactions in the presence of…
A Pseudo-BCS Wavefunction from Density Matrix Decomposition:Application in Auxiliary-Field Quantum Monte Carlo
Zhiyu Xiao, Hao Shi, Shiwei Zhang
We present a method to construct pseudo-BCS wave functions from the one-body density matrix. The resulting many-body wave function, which can be produced for any fermion systems, i…
The neutron returning time in a linear potential
Zhi Xiao, Shuang Zheng, Ji-Cai Liu
In this paper, we calculate the quantum time delays for neutron scattering off the Earth's linear gravitational potential. The quantum time delays are obtained by subtracting the c…
The CPT-violating effects on neutron's gravitational bound state
Zhi Xiao
Analytical solutions with effective CPT-violating spin--gravity corrections to the neutron's gravitational bound states are obtained. The helicity-dependent phase evolution due to…
The CPT-violating effects on neutrons' gravitational bound state
Zhi Xiao, Lijing Shao
In this work, the CPT-violating (CPTV) interactions on neutrons' gravitational bound state are studied. With simple analytical solutions, we provide a preliminary investigation on…
Lorentz-violating scalar Hamiltonian and equivalence principle in a static metric
Zhi Xiao
In this paper, we obtain a nonrelativistic Hamiltonian from the Lorentz-violating (LV) scalar Lagrangian in the minimal SME. The Hamiltonian is obtained by two different methods. O…
