New physics in the charged relativistic Bose gas using zeta-function regularization?
Antonio Filippi
The multiplicative anomaly, recently introduced in QFT, plays a fundamental role in solving some mathematical inconsistencies of the widely used zeta-function regularization method…
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.…
Multiplicative anomaly and finite charge density
Antonio Filippi
When dealing with zeta-function regularized functional determinants of matrix valued differential operators, an additional term, overlooked until now and due to the multiplicative…
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…
One-loop Effective Potential for a Fixed Charged Self-interacting Bosonic Model at Finite Temperature with its Related Multiplicative Anomaly
Emilio Elizalde, Antonio Filippi, Luciano Vanzo +1
The one-loop partition function for a charged self-interacting Bose gas at finite temperature in D-dimensional spacetime is evaluated within a path integral approach making use of…
