Topological Devil's staircase in a constrained kagome Ising antiferromagnet
Afonso Rufino, Samuel Nyckees, Jeanne Colbois +1
We show that the constrained Ising model on the kagome lattice with infinite first and third neighbor couplings undergoes an infinite series of thermal first-order transitions at w…

Tensor-network study of the ground state of maple-leaf Heisenberg antiferromagnet
Samuel Nyckees, Pratyay Ghosh, Frédéric Mila
We study the quantum phase diagram of the spin- nearest-neighbor Heisenberg model on the maple-leaf lattice using infinite projected entangled pair states (iPEPS) combined wit…

Symmetry breaking and competing valence bond states in the star lattice Heisenberg antiferromagnet
Pratyay Ghosh, Jan Koziol, Samuel Nyckees +2
We investigate the ground state phase diagram of the spin- antiferromagnetic Heisenberg model on the star lattice using infinite projected entangled pair states (iPEPS) and hi…
