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…
Composite Quantum Geometry and Semiclassical Dynamics
Henry Davenport, Yoonseok Hwang, Johannes Knolle +1
We derive semiclassical equations of motion for general composite bound states in insulators and semiconductors, covering excitations such as excitons and trions. For neutral compo…
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…
Uncovering Exotic Paired States in the 2D Spin-Imbalanced Fermi Gas with Neural Wave Functions
Wan Tong Lou, Gino Cassella, Andres Perez Fadon +5
We study the zero-temperature phase diagram of the 2D spin-imbalanced Fermi gas with short-ranged attractive interactions using the recently developed neural network variational Mo…
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…
Probing topology in thin films with quantum Sondheimer oscillations
Léo Mangeolle, Johannes Knolle
Sondheimer oscillations (SO) are magnetoresistance oscillations occurring in thin films due to the commensurability between cyclotron motion and sample thickness, and are tradition…
Interaction-Mediated Non-Reciprocal Dynamics in Open Quantum Systems: From an Exactly Solvable Model to Generic Behavior
Pietro Borchia, Johannes Knolle, Andreas Nunnenkamp
Reservoir engineering has emerged as a powerful paradigm to realize non-reciprocal dynamics in open quantum many-body systems. Here, we show that density-density interactions can t…
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…
Current-tunable room temperature ferromagnetism and current-driven phase transitions
Jianping Guo, Peng Rao, Xinhao Huang +9
It is generally assumed that the application of a charge-current in ferromagnetic metals suppresses their ferromagnetic order through trivial Joule heating. Here, we demonstrate th…
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…
