Abstract:
Intermediate mass fragments(2Z≤11) emitted from 294 MeV 20Ne+159Tb reaction have been measured by △E-E telescope counters at the angle of 10°—150°region.The energy spectra of the fragments at back angle(>90°) have bell shape,and their peaks locate ne...

Abstract:
We investigate the phase transitions of Abelian lattice gauge theories at finite temperature with the variational cumulant expansion.Our results are in good agreement with the exact resaults and the basic predictions made by Sevtitsky and Yaffe.

Abstract:
We propose a new quantization scheme with which and the equation of motion the quantization problem of both independent and dependent interacting fields in QED can be solved simultaneously.When the external gauge field Aμ(s)≠0(i.e.the Fermion field ￠...
