Phase diagram of the - Heisenberg Model on the Maple-Leaf Lattice: Neural networks and density matrix renormalization group
Jonas Beck, Jonathan Bodky, Johannes Motruk +3
We microscopically analyze the nearest neighbor Heisenberg model on the maple-leaf lattice through neural quantum states (NQS) and infinite density matrix renormalization group (iD…

$\require{mhchem}$Quantum paramagnetism in the decorated square-kagome antiferromagnet $\ce{Na6Cu7BiO4(PO4)4Cl3}$
Nils Niggemann, Nikita Astrakhantsev, Arnaud Ralko +9
$\require{mhchem}$The square-kagome lattice Heisenberg antiferromagnet is a highly frustrated Hamiltonian whose material realizations have been scarce. We theoretically investigate…

Pseudo-fermion functional renormalization group for spin models
Tobias Müller, Dominik Kiese, Nils Niggemann +5
For decades, frustrated quantum magnets have been a seed for scientific progress and innovation in condensed matter. As much as the numerical tools for low-dimensional quantum magn…
