¡Nos trasladamos! E-Prints cerrará el 7 de junio.

En las próximas semanas vamos a migrar nuestro repositorio a una nueva plataforma con muchas funcionalidades nuevas. En esta migración las fechas clave del proceso son las siguientes:

7 de junio: congelación de E-Prints. A partir de este momento, no se podrá hacer ningún depósito ni cambio, modificación o edición.
12 al 30 de junio: migración de E-Prints a Docta Complutense, comprobación y visto bueno de la migración
3 de julio: entrada en producción de Docta Complutense

Es muy importante que cualquier depósito se realice en E-Prints Complutense antes del 7 de junio. En caso de urgencia para realizar un depósito, se puede comunicar a docta@ucm.es.

Abstract

The thermodynamical partition functions for both the Schwinger and Thirring models are evaluated. The imaginary time formalism of quantum field theory at finite temperature and pathintegral methods are used. For the Schwinger model, the partition function displays two features: (i) no physical (transverse) photons exist in 1+1 dimensions; (ii) the theory also describes just free massive bosons. For the Thirring model, the partition function equals that for free massless fermions. The complete thermodynamical propagators and the energies per unit volume at finite temperature are also given.
