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…
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…
Simplex Crystal Ground State and Magnetization Plateaus in the Spin- Heisenberg Model on the Ruby Lattice
Pratyay Ghosh, Frédéric Mila
We investigate the spin- Heisenberg antiferromagnet on the ruby lattice with uniform first- and second-neighbor interactions, which forms a two-dimensional network of corner-s…
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…
Magnetic ordering in out-of-plane artificial spin systems based on the Archimedean lattices
Aleksandra Pac, Gavin M. Macauley, Jamie R. Massey +4
Artificial spin systems, sometimes referred to as artificial spin ices, are arrays of coupled nanoscale magnets that order according to the lattice geometry, nanomagnet shape and m…
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…
