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…
Self-organization of atoms in a cavity field: threshold, bistability and scaling laws
J. K. Asboth, P. Domokos, H. Ritsch +1
We present a detailed study of the spatial self-organization of laser-driven atoms in an optical cavity, an effect predicted on the basis of numerical simulations [P. Domokos and H…
Crystalline ground states for classical particles
Andras Suto
Pair interactions whose Fourier transform is nonnegative and vanishes above a wave number K_0 are shown to give rise to periodic and aperiodic infinite volume ground state configur…
Monte Carlo study of half-magnetization plateau and magnetic phase diagram in pyrochlore antiferromagnetic Heisenberg model
Yukitoshi Motome, Karlo Penc, Nic Shannon
The antiferromagnetic Heisenberg model on a pyrochlore lattice under external magnetic field is studied by classical Monte Carlo simulation. The model includes bilinear and biquadr…
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…
Strong disorder renormalization group on fractal lattices: Heisenberg models and magnetoresistive effects in tight binding models
R. Mélin, B. Douçot, F. Iglói
We use a numerical implementation of the strong disorder renormalization group (RG) method to study the low-energy fixed points of random Heisenberg and tight-binding models on dif…
