Ensemble Inequivalence and the Spin-Glass Transition
Zsolt Bertalan, Kazutaka Takahashi
We report on the ensemble inequivalence in a many-body spin-glass model with integer spin. The spin-glass phase transition is of first order for certain values of the crystal field…

Stability in microcanonical many-body spin glasses
Zsolt Bertalan, Kazutaka Takahashi
We generalize the de Almeida-Thouless line for the many-body Ising spin glass to the microcanonical ensemble and show that it coincides with the canonical one. This enables us to d…

Ensemble Inequivalence in the Ferromagnetic p-spin Model in Random Fields
Zsolt Bertalan, Takehiro Kuma, Yoshiki Matsuda +1
We study the effect that randomness has on long-range interacting systems by using the ferromagnetic Ising model with -body interactions in random fields. The case with p=2 yiel…
