  vacuum energy
The two-loop expression for the vacuum energy density in a constant magnetic field is obtained on the basis of the chiral perturbation theory.
      
Vacuum energy and the universe in special relativity
      
The problem of the cosmological constant and vacuum energy is usually thought of as the subject of general relativity.
      
However, vacuum energy is important for the Universe even in the absence of gravity, i.e., in the case when Newton's constant G is exactly zero, G=0.
      
We discuss the response of the vacuum energy to the perturbations of the quantum vacuum in special relativity and find that, as in general relativity, the vacuum energy density is on the order of the energy density of matter.

The concept of Bose Condensation of Higgs fields is applied to SU(2) Higgs φ~4 model. It is proved that under the selfinteractions between Higgs fields, when the sum of condensation densities of charged complex fields and neutral complex fieldsremains fixed, the vaccum energies of symmetrical and asymmetrical condensations are equal to each other whereas the elementary excitation spectra all include three Goldstone particles and a particle with mass 2~(1/2)m. Then by introducing a coupling between massless electron...

The concept of Bose Condensation of Higgs fields is applied to SU(2) Higgs φ~4 model. It is proved that under the selfinteractions between Higgs fields, when the sum of condensation densities of charged complex fields and neutral complex fieldsremains fixed, the vaccum energies of symmetrical and asymmetrical condensations are equal to each other whereas the elementary excitation spectra all include three Goldstone particles and a particle with mass 2~(1/2)m. Then by introducing a coupling between massless electron and neutral Higgs field, we derive an expression of electron mass which coincides with that in Weinberg-Salam model.

本文推广Higgs场的玻色凝结概念到SU(2)Higgs φ~4模型。证明在Higgs场的自作用下,当荷电复场和中性复场的凝聚密度之和不变时,对称凝聚和不对称凝聚的真空能量相同,元激发谐也都包含三个Goldstone粒子和一个质量为2~(1/2) m的粒子,并由此出发,通过引入无质量涡电子和中性Higgs场的耦合,给出了和Weinberg-Salam模型相符的电子质量。

The most probable escape path (MPEP) between vacuums, determined with WKBmethod, is expressed by different functions corresponding to the classical solutions offield equations in Euclidean space or in Minkowski Space while the potential U ishigher or lower than the energy E respectively. But the WKB method will not be validnearby the turning point u=E. In this paper we give the equations satisfied in thevicinity of turning point by MPEP which connects E_4 and M_4 solutions.

The most probable escape path (MPEP) between vacuums, determined with WKBmethod, is expressed by different functions corresponding to the classical solutions offield equations in Euclidean space or in Minkowski Space while the potential U ishigher or lower than the energy E respectively. But the WKB method will not be validnearby the turning point u=E. In this paper we give the equations satisfied in thevicinity of turning point by MPEP which connects E_4 and M_4 solutions. The energylevels of physical θ vacuums obtained in terms of periodic potential in winding numberspace are not equal to the energy of original vacuums. The MPEP and also the poten-tial depend on positions of energy levels. Conversly, the energy levels are determined bypotential. We explain how to account this selfconsistently.

已知,用WKB方法求得的真空之间最可几逃逸路径(MPEP)当位势u大于能量E或u

By applying Gilkey's result, we obtain the coefficient a_3 in DeWitt-Schwinger proper time expansion of the Green function for scalar, spinor and vector fields respectively, so finally we succeed in obtaining the renormalized vacuum stress-energy tensor for deSitter space-time in large mass approximation.
