Landscape of incompressible crystals of hard-core bosons on the square-kagome lattice
Pratyay Ghosh
We investigate a hard-core boson model on the square-kagome lattice using hierarchical mean-field theory beyond the conventional unit-cell description. We show that the conventiona…
Zoology of Altermagnetic-type Non-collinear Magnets on the Maple Leaf Lattice
Pratyay Ghosh, Ronny Thomale
We define unconventional non-collinear magnetic ground states on the maple leaf lattice (MLL) distinguished by the selective breaking or preservation of time reversal ($\mathcal{T}…
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…
Chiral crossroads in : a tale of frustration in maple leaf lattice
Pratyay Ghosh
Motivated by the recent observation of a uniform vector chirality (UVC) magnetic order in the maple-leaf lattice (MLL) realization via powder neutron scatterin…
