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…
Approaching Kasteleyn transition in frustrated quantum Heisenberg antiferromagnets
Katarina Karlova, Afonso Rufino, Taras Verkholyak +5
We show that the Kasteleyn transition, the abrupt proliferation of infinite strings of defects in classical dimer and related models, can also be relevant for frustrated 2d quantum…
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…
Observation of Unprecedented Fractional Magnetization Plateaus in a New Shastry-Sutherland Ising Compound
Lalit Yadav, Afonso Rufino, Rabindranath Bag +10
Geometrically frustrated magnetic systems, such as those based on the Shastry-Sutherland lattice (SSL), offer a rich playground for exploring unconventional magnetic states. The de…
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…
