Chiral-lattice degrees of freedom can offer novel chirality-selective functionalities for thermotronic applications. Chiral phonons, which carry both heat and angular momentum, can arise from broken chiral degeneracy in phonon bands or from angular momentum transfer from photons or spins. Here, we demonstrate a nanosca...

Strong interplay among electron, spin, and lattice degrees of freedom in condensed matter provides a wide range of emergent phenomena, and also serves as a firm basis for the useful cross-coupled electronic, magnetic, and structural functionalities. Here, we present metallic and magnetic FeRh as a representative system...

Quantum materials host a rich spectrum of low-energy collective excitations- phonons, magnons, plasmons, polaritons, and Higgs modes- that fundamentally govern their emergent properties, but remain inaccessible to conventional linear THz spectroscopy when nonlinear pathways overlap or non-perturbative dynamics emerge....
