Quantum fluctuation in an inhomogeneous background and its influence on the phase transition in a finite volume system
Xiaogang Li, Song Shu, Jia-Rong Li
We have studied the grand potential and phase transitions of an inhomogeneous finite volume spherical quark system. First the finite volume effects are considered by applying the m…
Vacuum and thermal fluctuation energies of a soliton at finite temperatures
Song Shu, Xiaogang Li, Jia-Rong Li
We have studied the vacuum and thermal fluctuation energies of a soliton at finite temperatures. First the vacuum energy coming from the Dirac sea is calculated by a summation of t…
Bubble dynamics in a strong first-order quark-hadron transition
Shuying Zhou, Song Shu, Hong Mao
We investigate the dynamics of a strong first-order quark-hadron transition driven by cubic interaction via homogeneous bubble nucleation in the Friedberg-Lee model. The one-loop e…
The baryon mass calculation in the chiral soliton model at finite temperature and density
Hui Zhang, Renda Dong, Song Shu
In the mean-field approximation, we have studied the soliton which is embedded in a thermal medium within the chiral soliton model. The energy of the soliton or the baryon mass in…
The vacuum tunnelling and the crossover of deconfinement in Friedberg-Lee model
Song Shu, Jia-Rong Li
We have discussed the vacuum tunnelling in Friedberg-Lee model. The tunnelling coefficient is derived in the field configuration space by calculating the transition amplitude using…
Expanding the thermodynamical potential and the analysis of the possible phase diagram of deconfinement in FL model
Song Shu, Jia-Rong Li
The deconfinement phase transition is studied in the FL model at finite temperature and chemical potential. At MFT approximation, the phase transition can only be the first order i…

Song Shu, Jia-Rong Li
The non-topological FL model is studied at finite temperature and density. The soliton solutions of the FL model in deconfinement phase transition are solved and thoroughly discuss…
Bose-Einstein condensation in linear sigma model at Hartree and large N approximation
Song Shu, Jia-Rong Li
The BEC of charged pions is investigated in the framework of O(4) linear sigma model. By using Cornwall-Jackiw-Tomboulis formalism, we have derived the gap equations for the effect…
The linear sigma model at a finite isospin chemical potential
Hong Mao, Nicholas Petropoulos, Song Shu +1
The effect of finite isospin chemical potential to the effective masses of the mesons at finite temperature is investigated in the framework of the O(4) linear sigma model with exp…
