Ferromagnetism and antiferromagnetism in the quantum Ising model
L.N. Epele, Huner Fanchiotti A, Carlos A. García Canal
The Ising model in a magnetic field is studied in its quantum version. The particular realization of the renormalization group proposed gives both the ferromagnetic and antiferromagnetic fixed points. The critical exponents are obtained in a very simple analytical way.
