Variations in Discrete Mechanics and Field Theory
Han-Ying Guo, Ke Wu
Some problems on variations are raised for classical discrete mechanics and field theory and the difference variational approach with variable step-length is proposed motivated by…
Long-range Effect on the Curie Temperature of Ferroelectric Films
Dong-Lai Yao, Yin-Zhong Wu, Zhen-Ya Li
In this paper, the Curie temperature of ferroelectric films is studied using spin-1/2 transverse Ising model with long-range interaction within the framework of the effective-field…
Calculation of pure annihilation type decay
Cai-Dian Lu
The rare decay can occur only via annihilation type diagrams in the standard model. We calculate this decay in perturbative QCD approach with Sudakov resummation.…
Fake CPT Violation in Disappearance Neutrino Oscillations
Zhi-zhong Xing
We make an analysis of the fake CPT-violating asymmetries between the survival probabilities of neutrinos and antineutrinos, induced by the terrestrial matter effects, in three dif…
Classical collisional trajectories as the source of strong-field double ionization of helium in the knee regime
Li-Bin Fu, Jie Liu, Jing Chen +1
In this paper, a quasistatic model is extended to describe the double ionization of Helium in intense linearly polarized field, yielding achieve an insight to the two-electron corr…
Exchange Bias in Ferromagnetic/Compensated Antiferromagnetic Bilayers
D. S. Deng, X. F. Jin, Ruibao Tao
By means of micromagnetic spin dynamics calculations, a quantitative calculation is carried out to explore the mechanism of exchange bias (EB) in ferromagnetic (FM)/compensated ant…
