Systematic Analysis of Crystalline Phases in Bosonic Lattice Models with Algebraically Decaying Density-Density Interactions

J. A. Koziol, A. Duft, G. Morigi +1

We propose a general approach to analyse diagonal ordering patterns in bosonic lattice models with algebraically decaying density-density interactions on arbitrary lattices. The ke…

Continuously varying critical exponents in long-range quantum spin ladders

P. Adelhardt, K. P. Schmidt

We investigate the quantum-critical behavior between the rung-singlet phase with hidden string order and the Néel phase with broken $S U (2)$ -symmetry on quantum spin ladders with al…
