Spin-spin correlations of the spin-ladder compound (CHN)CuBr measured by magnetostriction and comparison to Quantum Monte Carlo results
Fabrizio Anfuso, Markus Garst, Achim Rosch +4
Magnetostriction and thermal expansion of the spin-ladder compound piperidinium copper bromide (CHN)CuBr are analyzed in detail. We find perfect agreement betwee…
Diverging thermal expansion of the spin-ladder system (CHN)CuBr
T. Lorenz, O. Heyer, M. Garst +4
We present high-resolution measurements of the -axis thermal expansion and magnetostriction of piperidinium copper bromide \hp. The experimental data at low temperatures i…
Universal alternating order around impurities in antiferromagnets
Sebastian Eggert, Olav F. Syljuasen, Fabrizio Anfuso +1
The study of impurities in antiferromagnets is of considerable interest in condensed matter physics. In this paper we address the elementary question of the effect of vacancies on…
Fragility of String Orders
F. Anfuso, A. Rosch
One-dimensional gapped systems are often characterized by a 'hidden' non-local order parameter, the so-called string order. Due to the gap, thermodynamic properties are robust agai…
Doping effects in low dimensional antiferromagnets
Sebastian Eggert, Fabrizio Anfuso
The study of impurities in low dimensional antiferromagnets has been a very active field in magnetism ever since the discovery of high temperature superconductivity. One of the mos…
Interaction effects between impurities in low dimensional spin-1/2 antiferromagnets
Fabrizio Anfuso, Sebastian Eggert
We are considering the interplay between several non-magnetic impurities in the spin-1/2 Heisenberg antiferromagnet in chains, ladders and planes by introducing static vacancies in…
