Low energy structure of spiral spin liquids
Han Yan, Johannes Reuther
In this work we identify a previously unexplored type of topological defect in spiral spin liquids -- the momentum vortex -- and reveal its dominant role in shaping the low energy…
Quantitative functional renormalization for three-dimensional quantum Heisenberg models
Nils Niggemann, Johannes Reuther, Björn Sbierski
We employ a recently developed variant of the functional renormalization group method for spin systems, the so-called pseudo Majorana functional renormalization group, to investiga…
Pinwheel valence-bond-crystal ground state of the spin- Heisenberg antiferromagnet on the lattice
Nikita Astrakhantsev, Francesco Ferrari, Nils Niggemann +9
We investigate the nature of the ground-state of the spin- Heisenberg antiferromagnet on the lattice by complementary state-of-the-art numerical techniques,…
Dimerization tendencies of the pyrochlore Heisenberg antiferromagnet: A functional renormalization group perspective
Max Hering, Vincent Noculak, Francesco Ferrari +2
We investigate the ground state properties of the spin- pyrochlore Heisenberg antiferromagnet using pseudofermion functional renormalization group techniques. The first part o…
Magnetic field induced quantum spin liquid in the two coupled trillium lattices of KNi(SO)
Ivica Zivkovic, Virgile Favre, Catalina Salazar Mejia +19
Quantum spin liquids are exotic states of matter which form when strongly frustrated magnetic interactions induce a highly entangled quantum paramagnet far below the energy scale o…
Phase diagram of a distorted kagome antiferromagnet and application to Y-kapellasite
Max Hering, Francesco Ferrari, Aleksandar Razpopov +4
We investigate the magnetism of a previously unexplored distorted spin-1/2 kagome model consisting of three symmetry-inequivalent nearest-neighbor antiferromagnetic Heisenberg coup…
