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…
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…
Weakly first-order melting of the 1/3 plateau in the Shastry-Sutherland model
Samuel Nyckees, Philippe Corboz, Frédéric Mila
We investigate the thermal properties of the 1/3 plateau in the Shastry-Sutherland model with infinite projected entangled-pair states (iPEPS) by performing the imaginary time evol…
Critical line of the triangular Ising antiferromagnet in a field from a -symmetric corner transfer matrix algorithm
Samuel Nyckees, Afonso Rufino, Frédéric Mila +1
The corner transfer matrix renormalization group (CTMRG) algorithm has been extensively used to investigate both classical and quantum two-dimensional (2D) lattice models. The conv…
Tensor network investigation of the hard-square model
Samuel Nyckees, Frédéric Mila
Using the corner-transfer matrix renormalization group to contract the tensor network that describes its partition function, we investigate the nature of the phase transitions of t…
Commensurate-incommensurate transition in the chiral Ashkin-Teller model
Samuel Nyckees, Frédéric Mila
We investigate the classical chiral Ashkin-Teller model on a square lattice with the corner transfer matrix renormalisation group (CTMRG) algorithm. We show that the melting of the…
Identifying the Huse-Fisher universality class of the three-state chiral Potts model
Samuel Nyckees, Jeanne Colbois, Frédéric Mila
Using the corner-transfer matrix renormalization group approach, we revisit the three-state chiral Potts model on the square lattice, a model proposed in the eighties to describe c…
