The Mott metal-insulator transition in the 1D Hubbard model in an external magnetic field
Holger Frahm, Temo Vekua
We study the low energy behavior of the one dimensional Hubbard model across the Mott metal-insulator phase transition in an external magnetic field. In particular we calculate ele…

Correlation functions and excitation spectrum of the frustrated ferromagnetic spin-1/2 chain in an external magnetic field
T. Vekua, A. Honecker, H. -J. Mikeska +1
Magnetic field effects on the one-dimensional frustrated ferromagnetic chain are studied by means of effective field theory approaches in combination with numerical calculations ut…
