Spin- Kitaev-Heisenberg model on the honeycomb lattice: A high-order treatment via the many-body coupled cluster method
Marios Georgiou, Ioannis Rousochatzakis, Damian J. J. Farnell +2
We study the spin- Kitaev-Heisenberg model on the honeycomb lattice for , and , by using the coupled cluster method (CCM) of microscopic quantum many-body th…
Generalized Phase-Space Techniques to Explore Quantum Phase Transitions in Critical Quantum Spin Systems
N. M. Millen, R. P. Rundle, J. H. Samson +3
We apply the generalized Wigner function formalism to detect and characterize a range of quantum phase transitions in several cyclic, finite-length, spin- one-dimensio…
Frustrated spin- Heisenberg magnet on an -stacked honeycomb bilayer: High-order study of the collinear magnetic phases of the ---- model
P. H. Y. Li, R. F. Bishop
The zero-temperature phase diagram of the frustrated spin- ---- Heisenberg magnet on an -stacked honeycomb bilayer lattice is studied…
Non-Hermitian coupled cluster method for non-stationary systems and its interaction-picture reinterpretation
R. F. Bishop, M. Znojil
The interaction picture in a non-Hermitian realization is discussed in detail and considered for its practical use in many-body quantum physics. The resulting non-Hermitian interac…

R. F. Bishop, P. H. Y. Li, O. Götze +1
The zero-temperature phase diagram of the spin- ---- model on an -stacked square-lattice bilayer is studied using the coupled cluster…
The Interplay Between Lattice Topology, Frustration, and Spin Quantum Number in Quantum Antiferromagnets on Archimedean Lattices
D. J. J. Farnell, O. Götze, J. Schulenburg +3
The interplay between lattice topology, frustration, and spin quantum number, , is explored for the Heisenberg antiferromagnet (HAFM) on the eleven two-dimensional Archimedean l…
