Ground-state Entropy of the Ising model on a Frustrated lattice
B Sriram Shastry, Bill Sutherland, Frédéric Mila +1
We report the ground-state entropy of a 2-d Ising model on the Shastry-Sutherland lattice. We also study a generalization of this model, where a constraint on the zero temperature…
Non-linear spin wave theory in the strong easy-axis limit of the triangular XXZ model
Achille Mauri, Siebe Roose, Frédéric Mila
Motivated by recent experimental studies, we investigate the spectrum of the nearest-neighbour triangular XXZ model within the expansion, in the limit in which the exchange c…
Thermal Phase Diagram of the Square Lattice Ferro-antiferromagnetic Heisenberg Model
Olivier Gauthé, Frédéric Mila
Using state of the art tensor network computations combined with spin wave theory, we compute the finite temperature phase diagram of the spin 1/2 Heisenberg model on the…
Primary and Secondary Order Parameters in the Fully Frustrated Transverse Field Ising Model on the Square Lattice
Gabe Schumm, Hui Shao, Wenan Guo +2
Using quantum Monte Carlo simulations and field-theory arguments, we study the fully frustrated (Villain) transverse-field Ising model on the square lattice. We consider a "primary…
Phase diagram of the spin-1 Heisenberg model with three-site interactions on the square lattice
F. Michaud, F. Mila
We study the spin S=1 antiferromagnetic Heisenberg model on the square lattice with, in addition to the nearest-neighbor interaction, a three-site interaction of the form (S_i S_j)…
Phase diagram of the fully frustrated transverse-field Ising model on the honeycomb lattice
T. Coletta, J. -D. Picon, S. E. Korshunov +1
Motivated by the current interest in the quantum dimer model on the triangular lattice, we investigate the phase diagram of the closely related fully-frustrated transverse field Is…
Frustration induced plateaux in S>=1/2 Heisenberg spin ladders
F. Michaud, T. Coletta, S. R. Manmana +2
We study the T = 0 magnetization of frustrated two-leg spin ladders with arbitrary value of the spin S. In the strong rung limit, we use degenerate perturbation theory to prove tha…
Spontaneous plaquette formation in the SU(4) Spin-Orbital ladder
M. van den Bossche, P. Azaria, P. Lecheminant +1
The low-energy properties of the SU(4) spin-orbital model on a two-leg ladder are studied by a variety of analytical and numerical techniques. Like in the case of SU(2) models, the…
