Canonical strong coupling spin wave expansion of Kondo lattice magnets. II. Itinerant ferromagnets and topological magnon bands
M. Frakulla, J. Strockoz, D. S. Antonenko +1
In this paper we apply the canonical spin wave theory developed for itinerant Kondo lattice magnets in the strong coupling regime to Kondo ferromagnets, and address two general que…
Orbital piezomagnetic polarizability of pure insulating altermagnets in two dimensions
Beryl Bell, Jörn W. F. Venderbos
The distinctive symmetry properties of pure altermagnets make them natural candidates for piezomagnetism. Previous work motivated by the piezomagnetic properties of altermagnets ha…
Kondo-Heisenberg toy models: Comparison of exact results and spin wave expansion
M. Frakulla, J. Strockoz, D. S. Antonenko +1
In this paper we study a class of exactly solvable Kondo-Heisenberg toy models in one dimension, with the goal of comparing the exact low-energy excitations of the ferromagnetic gr…
Canonical strong coupling spin wave expansion of Kondo lattice magnets. I. Effective Hamiltonian via canonical transformation
J. Strockoz, M. Frakulla, D. Antonenko +1
This paper develops a systematic strong coupling spin wave expansion of itinerant Kondo lattice magnets, magnets in which local moment spins are Kondo coupled to itinerant charge d…
Flat band physics in the charge-density wave state of -TaS
Amir Dalal, Jonathan Ruhman, Jörn W. F. Venderbos
1-TaS is the only insulating transition-metal dichalcogenide (TMD) with an odd number of electrons per unit cell. This insulating state is non-magnetic, making it a potentia…
Signatures of Z Vestigial Potts-nematic order in van der Waals antiferromagnets
Zhuoliang Ni, Daniil S. Antonenko, W. Joe Meese +8
Layered van der Waals magnets have attracted much recent attention as a promising and versatile platform for exploring intrinsic two-dimensional magnetism. Within this broader clas…
Doping-induced nematic and stripe orders within the charge density wave state of TiSe
Daniel Muñoz-Segovia, Jörn W. F. Venderbos, Adolfo G. Grushin +1
In this work, we present a theory to address conflicting experimental claims regarding the charge density wave (CDW) state in TiSe, including whether there is a single or multi…
Electric-field-tunable electronic nematic order in twisted double-bilayer graphene
Rhine Samajdar, Mathias S. Scheurer, Simon Turkel +4
Graphene-based moiré systems have attracted considerable interest in recent years as they display a remarkable variety of correlated phenomena. Besides insulating and superconducti…
Universal moiré nematic phase in twisted graphitic systems
Carmen Rubio-Verdú, Simon Turkel, Larry Song +12
Graphene moiré superlattices display electronic flat bands. At integer fillings of these flat bands, energy gaps due to strong electron-electron interactions are generally observed…
Nematicity with a twist: rotational symmetry breaking in a moiré superlattice
Rafael M. Fernandes, Jörn W. F. Venderbos
Motivated by recent reports of nematic order in twisted bilayer graphene (TBG), we investigate the impact of the triangular moiré superlattice degrees of freedom on nematicity. In…
Observation of three-state nematicity in the triangular lattice antiferromagnet Fe NbS
Arielle Little, Changmin Lee, Caolan John +9
Nematic order is the breaking of rotational symmetry in the presence of translational invariance. While originally defined in the context of liquid crystals, the concept of nematic…
