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…
