Unconventional entanglement scaling and quantum criticality in the long-range spin-one Heisenberg chain with single-ion anisotropy
Patrick Adelhardt, Sean R. Muleady, Kai P. Schmidt +1
Long-range interactions can fundamentally reshape the low-energy properties of low-dimensional quantum matter, altering both continuous symmetry breaking and topological phenomena.…

Quantum-critical and dynamical properties of the XXZ bilayer with long-range interactions
Patrick Adelhardt, Antonia Duft, Kai Phillip Schmidt
We study the XXZ square lattice bilayer model with antiferromagnetic non-frustrating long-range interactions that decay as a power law with the distance. Employing large-scale high…

Quantum Phase Diagram of the Bilayer Kitaev-Heisenberg Model
Elahe Samimi, Antonia Duft, Patrick Adelhardt +2
We study the ground-state phase diagram of the spin- Kitaev-Heisenberg model on the bilayer honeycomb lattice with large-scale tensor network calculations based on the infinit…
