Competing magnetic and spin vestigial orders from continuum field theory
Niccolò Francini, Lukas Janssen
We study magnetic systems featuring competing antiferromagnetic and spin-nematic phases, described by dipolar primary and quadrupolar secondary order parameters. While the antiferr…
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…
Ferrimagnetism from quantum fluctuations in Kitaev materials
Niccolò Francini, Pedro M. Cônsoli, Lukas Janssen
Ferrimagnetism appears in the temperature-field phase diagrams of several candidate Kitaev materials, such as the honeycomb cobaltates NaCoTeO and NaCoSbO.…
Ferrimagnetism from triple-q order in NaCoTeO
Niccolò Francini, Lukas Janssen
The candidate Kitaev magnet NaCoTeO exhibits a characteristic ferrimagnetic response at low temperatures, with a finite residual magnetization that changes sign at a co…
Higher-Rank Spin Liquids and Spin Nematics from Competing Orders in Pyrochlore Magnets
Niccolò Francini, Lukas Janssen, Daniel Lozano-Gómez
Pyrochlore magnets have proven to provide an excellent arena for the realization of a variety of many-body phenomena such as classical and quantum order-by-disorder, as well as spi…
Spin vestigial orders in extended Heisenberg-Kitaev models near hidden SU(2) points: Application to NaCoTeO
Niccolò Francini, Lukas Janssen
The honeycomb magnet NaCoTeO has recently been argued to realize an approximate hidden SU(2) symmetry that can be understood by means of a duality transformation. Using…
