Quantum relaxation and finite size effects in the XY chain in a transverse field after global quenches
Benjamin Blaß, Heiko Rieger, Ferenc Iglói
We consider global quenches in the quantum XY chain in a transverse field and study the nonequilibrium relaxation of the magnetization and the correlation function as well as the e…
Critical behavior of the frustrated antiferromagnetic six-state clock model on a triangular lattice
J. D. Noh, H. Rieger, M. Enderle +1
We study the anti-ferromagnetic six-state clock model with nearest neighbor interactions on a triangular lattice with extensive Monte-Carlo simulations. We find clear indications o…
Evidence for Kosterlitz-Thouless type orientational ordering of CFBr monolayers physisorbed on graphite
S. Faßbender, M. Enderle, K. Knorr +2
Monolayers of the halomethane CFBr adsorbed on graphite have been investigated by x-ray diffraction. The layers crystallize in a commensurate triangular lattice. On cooling the…
Random quantum magnets with broad disorder distribution
D. Karevski, Y-C. Lin, H. Rieger +2
We study the critical behavior of Ising quantum magnets with broadly distributed random couplings (J), such that , , for large (Lévy fl…
Long range correlations in the non-equilibrium quantum relaxation of a spin chain
F. Igloi, H. Rieger
We consider the non-stationary quantum relaxation of the Ising spin chain in a transverse field of strength h. Starting from a homogeneously magnetized initial state the system app…
Comparative study of the critical behavior in one-dimensional random and aperiodic environments
F. Igloi, D. Karevski, H. Rieger
We consider cooperative processes (quantum spin chains and random walks) in one-dimensional fluctuating random and aperiodic environments characterized by fluctuating exponents ome…
