Incommensurate Spin-Density Waves in a Frustrated Maple-Leaf Lattice Ferromagnet
Paul L. Ebert, Yasir Iqbal, Alexander Wietek
We study how ferromagnetism breaks down in the spin- nearest-neighbor Heisenberg model on the maple-leaf lattice with ferromagnetic and antiferromagnetic ,…
Thermodynamics of the Heisenberg antiferromagnet on the maple-leaf lattice
Robin Schäfer, Paul L. Ebert, Noah Hassan +3
We study the Heisenberg antiferromagnet on the maple-leaf lattice using several numerical approaches, focusing on the numerical linked-cluster expansion (NLCE), which exhibits an u…
XDiag: Exact Diagonalization for Quantum Many-Body Systems
Alexander Wietek, Luke Staszewski, Martin Ulaga +6
Exact diagonalization (ED) is a cornerstone technique in quantum many-body physics, enabling precise solutions to the Schrödinger equation for interacting quantum systems. Despite…
Competing Paramagnetic Phases in the Maple-Leaf Heisenberg Antiferromagnet
Paul L. Ebert, Yasir Iqbal, Alexander Wietek
We establish a remarkably rich ground state phase diagram in the maple-leaf lattice spin- Heisenberg antiferromagnet as a function of the three symmetry-inequivalent nearest-n…
