Discrete Laplacian Structure and Kernel Reduction of the Gap Equation in Gross--Neveu Model at Imaginary Chemical Potential
Evangelos G. Filothodoros
We observe a remarkable mathematical structure in the gap equations of the large- Gross--Neveu model at imaginary chemical potential in odd spacetime dimensions . We s…

Fermionic and bosonic partition functions at imaginary chemical potential as Bloch functions
Evangelos G. Filothodoros
We point out that the phase transitions of the Gross-Neveu and models at finite temperature and imaginary chemical potential can be mapped to transformations of Hu…

The fermion-boson map for large d
Evangelos G. Filothodoros, Anastasios C. Petkou, Nicholas D. Vlachos
We show that the three-dimensional map between fermions and bosons at finite temperature generalises for all odd dimensions . We further argue that such a map has a nontrivial…
