Polylogarithmic Structure of Bragg Diffraction in Finite-Coherence Lattices
Evangelos G. Filothodoros
We develop a polylogarithmic structure for Bragg diffraction based on a weighted multi-plane interference model. Within this kind of construction, the scattering amplitude is expre…
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…
Bose-Fermi Mapping in Hubbard Models at Imaginary Chemical Potential and Phase-Induced Fermionization
Evangelos G. Filothodoros
We find a mapping between the attractive Fermi-Hubbard model and the repulsive Bose-Hubbard model at finite temperature and at imaginary chemical potential . We show, by usin…
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…
