Correlations and enlarged superconducting phase of - chains of ultracold molecules on optical lattices
Salvatore R. Manmana, Marcel Möller, Riccardo Gezzi +1
We compute physical properties across the phase diagram of the - chain with long-range dipolar interactions, which describe ultracold polar molecules on optical lattice…
Automated construction of -invariant matrix-product operators from graph representations
Sebastian Paeckel, Thomas Köhler, Salvatore R. Manmana
We present an algorithmic construction scheme for matrix-product-operator (MPO) representations of arbitrary -invariant operators whenever there is an expression of the local…
Anisotropy crossover in the frustrated Hubbard model on four-chain cylinders
G. Ehlers, B. Lenz, S. R. Manmana +1
Motivated by dimensional crossover in layered organic salts, we determine the phase diagram of a system of four periodically coupled Hubbard chains with frustration at half fil…
Finite-Temperature Dynamics and Thermal Intraband Magnon Scattering in Haldane Spin-One Chains
Jonas Becker, Thomas Köhler, Alexander C. Tiegel +3
The antiferromagnetic spin-one chain is considerably one of the most fundamental quantum many-body systems, with symmetry protected topological order in the ground state. Here, we…
