Affine lattice construction of spiral surfaces in classical Heisenberg models
Péter Balla, Yasir Iqbal, Karlo Penc
Frustration in classical spin models can lead to degenerate ground states without long range order. In reciprocal space, these degeneracies appear as manifolds of wave vectors, the…
Breathing chromium spinels: a showcase for a variety of pyrochlore Heisenberg Hamiltonians
Pratyay Ghosh, Yasir Iqbal, Tobias Müller +6
We address the long-standing problem of the microscopic origin of the richly diverse phenomena in the chromium breathing pyrochlore material family. Combining electronic structure…
Quantum paramagnetism and helimagnetic orders in the Heisenberg model on the body centered cubic lattice
Pratyay Ghosh, Tobias Müller, Francesco Parisen Toldin +5
We investigate the spin Heisenberg model on the body centered cubic lattice in the presence of ferromagnetic and antiferromagnetic nearest-neighbor , second-neighbor…
