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. © 2012 Elsevier B.V.

Abstract
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. © 2012 Elsevier B.V.File in questo prodotto:
