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 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…
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…
Monte Carlo based techniques for quantum magnets with long-range interactions
P. Adelhardt, J. A. Koziol, A. Langheld +1
Long-range interactions are relevant for a large variety of quantum systems in quantum optics and condensed matter physics. In particular, the control of quantum-optical platforms…
Order-by-disorder in the antiferromagnetic -- transverse-field Ising model on the ruby lattice
A. Duft, J. A. Koziol, P. Adelhardt +2
We investigate the quantum phase diagram of the -- antiferromagnetic transverse-field Ising model on the ruby lattice. In the low-field limit we derive an effective…
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 -symmetry on quantum spin ladders with al…
Scaling at quantum phase transitions above the upper critical dimension
A. Langheld, J. A. Koziol, P. Adelhardt +2
The hyperscaling relation and standard finite-size scaling (FSS) are known to break down above the upper critical dimension due to dangerous irrelevant variables. We establish a co…
Kitaev honeycomb antiferromagnet in a field: quantum phase diagram for general spin
Saeed S. Jahromi, Max Hörmann, Patrick Adelhardt +4
We combine tensor-network approaches and high-order linked-cluster expansions to investigate the quantum phase diagram of the antiferromagnetic Kitaev's honeycomb model in a magnet…
Quantum criticality and excitations of a long-range anisotropic -chain in a transverse field
P. Adelhardt, J. A. Koziol, A. Schellenberger +1
The critical breakdown of a one-dimensional quantum magnet with long-range interactions is studied by investigating the high-field polarized phase of the anisotropic XY model in a…
Quantum phase transitions to topological Haldane phases in spin-one chains studied by linked-cluster expansions
P. Adelhardt, J. Gritsch, M. Hille +2
We use linked-cluster expansions to analyze the quantum phase transitions between symmetry unbroken trivial and topological Haldane phases in two different spin-one chains. The fir…
