$\require{mhchem}$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…
Sublattice modulated superconductivity in the Kagome Hubbard model
Tilman Schwemmer, Hendrik Hohmann, Matteo Dürrnagel +8
We identify a superconducting order featuring spatial pair modulations on the kagome lattice subject to onsite Hubbard U and nearest neighbor V interactions. Within our functional…
Effective spin-1 breathing kagome Hamiltonian induced by the exchange hierarchy in the maple leaf mineral bluebellite
Pratyay Ghosh, Tobias Müller, Yasir Iqbal +2
As a highly frustrated model Hamiltonian with an exact dimer ground state, the Heisenberg antiferromagnet on the maple leaf lattice is of high theoretical interest, and a material…
Maple Leaf Antiferromagnet in a Magnetic Field
Pratyay Ghosh, Jannis Seufert, Tobias Müller +2
We analyze the quantum antiferromagnet on the maple leaf lattice in the presence of a magnetic field. Starting from its exact dimer ground state and for a magnetic field strength o…
