The last few years have seen an explosion of interest in hydrodynamic effects in interacting
electron systems in ultra-pure materials. One such material, graphene, is not only an …

Growing technical demand for thermal management stems from the pursuit of high–efficient
energy utilization and the reuse of wasted thermal energy, which necessitates the …

Extending the notion of symmetry protected topological phases to insulating
antiferromagnets (AFs) described in terms of opposite magnetic dipole moments associated …

Magnon, the quanta of spin waves, can serve as an efficient spin information carrier for
memory and logic applications, with the advantages of the Joule-heating free induced low …

Nickel (II) oxide is a prominent candidate for spintronic and spin-caloritronic applications
operating at room temperature. Although there are extensive studies on nickel oxide, the …

Recently, the study of quantum materials through thermal characterization methods has
attracted much attention. These methods, although not as widely used as electrical methods …

Magnons in ferromagnets behave as a viscous fluid over a length scale, the momentum-
relaxation length, below which momentum-conserving scattering processes dominate. We …

Recent experiments have shown an indication of a hydrodynamic magnon behavior in
ultrapure ferromagnetic insulators; however, its direct observation is still lacking. Here, we …

Low-energy spin excitations in any long-range ordered magnetic system in the absence of
magnetocrystalline anisotropy are gapless Goldstone modes emanating from the ordering …

The spin ladder compounds (Sr, Ca, La, Y) 14Cu24O41, known for their large magnon
thermal conductivity, show great promise for thermal management and spin caloritronic …
