Rhombohedral Multilayer Graphene as a -Wave Magnet
Rintaro Eto, Johannes Knolle
We propose rhombohedral multilayer graphene in an applied in-plane magnetic field as a highly tunable platform for nonrelativistic collinear -wave magnetism. The orbital couplin…
Vestigial altermagnetism
Peng Rao, Johannes Knolle
Interaction effects and fluctuations govern the phase diagram of systems with multiple competing phases. In particular, as individual phases are destroyed by increasing temperature…
Odd-parity magnons in the Haldane-Hubbard model from topological exciton condensation
Rintaro Eto, Johannes Knolle
Odd-wave magnets are the counterparts to even-wave altermagnets realizing odd-parity spin splitting. Normally discussed for noncollinear systems, they have recently been shown to a…
Dynamical dimer structure factor of the triangular Heisenberg antiferromagnet
Markus Drescher, Laurens Vanderstraeten, Roderich Moessner +2
The dynamical dimer structure factor is an observable probing spin-singlet excitations of quantum magnets distinct from those commonly studied by the spin structure factor. We repo…
Dichroic Raman probes for chiral edge modes
Avedis Neehus, Johannes Knolle
The identification and manipulation of charge-neutral fractionalized quasi-particles, in particular chiral edge modes (CEM), is a long-standing quest in physics. Remarkably, the mi…
Proximate quantum spin liquids and Majorana continua in magnetically ordered Kitaev magnets
Peng Rao, Roderich Moessner, Johannes Knolle
We study the spin excitation spectra in magnetically ordered phases proximate to the Kitaev quantum spin liquid (KQSL). Although the low-energy universal features should be governe…
Tuning the magnetic properties of Kitaev materials via the antiferromagnetic proximity effect: Novel phases and application to an -RuCl/MnPS bilayer
Pedro M. Cônsoli, Ezra Day-Roberts, Johannes Knolle +2
In recent years, the increasing level of control over van der Waals (vdW) heterostructures has opened new routes to tune the properties of quantum materials. Motivated by these dev…
Unveiling the S=3/2 Kitaev Honeycomb Spin Liquids
Hui-Ke Jin, W. M. H. Natori, F. Pollmann +1
The S=3/2 Kitaev honeycomb model (KHM) is a quantum spin liquid (QSL) state coupled to a static Z gauge field. Employing an SO(6) Majorana representation of spin 3/2's, we find…
