Disorder-induced phases in the S=1 antiferromagnetic Heisenberg chain
Péter Lajkó, Enrico Carlon, Heiko Rieger +1
We use extensive density matrix renormalization group (DMRG) calculations to explore the phase diagram of the random S=1 antiferromagnetic Heisenberg chain with a power-law distrib…

Two-dimensional Ising model with self-dual biaxially correlated disorder
F. A. Bagamery, L. Turban, F. Igloi
We consider the Ising model on the square lattice with biaxially correlated random ferromagnetic couplings, the critical point of which is fixed by self-duality. The disorder repre…
