Another Exact Ground State of a 2D Quantum Antiferromagnet

Pratyay Ghosh, Tobias Müller, Ronny Thomale

We present the exact dimer ground state of a quantum antiferromagnet on the maple-leaf lattice. A coupling anisotropy for one of the three inequivalent nearest-neighbor bonds is su…

Pinwheel valence-bond-crystal ground state of the spin- $\frac{1}{2}$ Heisenberg antiferromagnet on the $s h u r ik e n$ lattice

Nikita Astrakhantsev, Francesco Ferrari, Nils Niggemann +9

We investigate the nature of the ground-state of the spin- $\frac{1}{2}$ Heisenberg antiferromagnet on the $s h u r ik e n$ lattice by complementary state-of-the-art numerical techniques,…
