Expansion for quantum perturbations in random spin systems

C. Itoi, K. Horie, H. Shimajiri +1

Energy eigenstates in the random transverse field Edwards-Anderson (EA) model and the random bond quantum Heisenberg XYZ model in a -dimensional finite cubic lattice are obtaine…

Absence of replica symmetry breaking in the Edwards-Anderson model near zero temperature

C. Itoi, H. Shimajiri, Y. Sakamoto

It is proven that the ground state is unique in the Edwards-Anderson model for almost all continuous random exchange interactions, and any excited state with the overlap less than…
