Quantum Coulomb Liquids of Different Rank in the Breathing Pyrochlore Antiferromagnet
Lasse Gresista, Daniel Lozano-Gómez, Daniel Lozano-Gómez +3
Emergent gauge fields and Coulomb liquids have long been central to the physics of frustrated pyrochlore magnets, yet their realization beyond conventional, i.e. rank-1 , spi…
Unconventional orders in the maple-leaf ferro-antiferromagnetic Heisenberg model
Lasse Gresista, Dominik Kiese, Simon Trebst +1
Motivated by the search for unconventional orders in frustrated quantum magnets, we present a multi-method investigation into the nature of the quantum phase diagram of the spin-$1…
Quantum effects on pyrochlore higher-rank U(1) spin liquids: Pinch-line singularities, spin nematics, and connections to oxide materials
Lasse Gresista, Daniel Lozano-Gómez, Matthias Vojta +2
Motivated by the magnetism of pyrochlore oxides, we consider the effect of quantum fluctuations in the most general symmetry-allowed nearest-neighbor Kramers exchange Hamiltonian o…
Noncoplanar orders and quantum disordered states in maple-leaf (anti)ferromagnets
Martin Gembé, Lasse Gresista, Heinz-Jürgen Schmidt +3
A promising route towards the realization of chiral spin liquids is the quantum melting of classically noncoplanar spin states via quantum fluctuations. In the classical realm, suc…
