相对论理想玻色-爱因斯坦凝聚体稳定性的研究

Study of stability of relativistic ideal Bose-Einstein condensates

F. Briscese, M. Grether, M. de Llano, G. A. Baker

摘要:

研究了有限温度下相对论性复标量玻色子场$T$在低于其临界玻色-爱因斯坦凝聚温度时的行为。结果表明,在相同的$T$下,有反玻色子的态比无反玻色子的态具有更高的熵、更低的Helmholtz自由能和更高的压强,但Gibbs自由能与其应有的值相同.这意味着没有反玻色子的组态是亚稳态的。结果推广为任意$d$空间维度。

英文摘要:

A relativistic complex scalar boson field at finite temperature $T$ is examined below its critical Bose-Einstein condensation temperature. It is shown that at the same $T$ the state with antibosons has higher entropy, lower Helmholtz free energy and higher pressure than the state without antibosons, but the same Gibbs free energy as it should. This implies that the configuration without antibosons is metastable. Results are generalized for arbitrary $d$ spatial dimensions.
