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…
Exact nematic and mixed magnetic phases driven by competing orders on the pyrochlore lattice
Niccolò Francini, Lukas Schmidt, Lukas Janssen +1
Pyrochlore magnets are a paradigmatic example of three-dimensional frustrated systems and provide an excellent platform for studying a variety of exotic many-body phenomena, includ…
Fragmented Spin Liquid and Shadow Pinch Points in Dipole-Octupole Pyrochlore Spin Systems
Daniel Lozano-Gómez, Han Yan
We study the classical dipole-octupole pyrochlore spin systems in an external magnetic field along the direction. We identify an intermediate fragmented spin liquid phase t…
Signatures of field-induced multi-color kagome spin liquids in the dipole-octupole pyrochlore
Edwin Kermarrec, Guanyue Chen, Daniel Lozano-Gómez +11
We report low-temperature magnetization and magnetostriction measurements on the dipole-octupole pyrochlore , revealing an unconventional field response for $…
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…
