Chemical potential and multiplicative anomaly
Antonio Filippi
The relativistic complex scalar field at finite temperature and in presence of a net conserved charge is studied in reference to recent developments on the multiplicative anomaly.…
Is the multiplicative anomaly relevant ?
Emilio Elizalde, Antonio Filippi, Luciano Vanzo +1
In a recent work, S. Dowker has shed doubt on a recipe used in computing the partition function for a matrix valued operator. This recipe, advocated by Benson, Bernstein and Dodels…
Is the multiplicative anomaly dependent on the regularization ?
Emilio Elizalde, Antonio Filippi, Luciano Vanzo +1
In a recent work, T.S. Evans has claimed that the multiplicative anomaly associated with the zeta-function regularization of functional determinants is regularization dependent. We…
Inclusion of Chemical Potential for Scalar Fields
Antonio Filippi
There are two possible methods for the inclusion of the chemical potential in a relativistic bosonic field theory. The most popular method has recently been criticised by some auth…
