Engineering Canalized Near-Field Radiative Heat Transfer between Fixed Nanoparticles with Twisted $\alpha$-MoO${}_3$ Trilayers

Yang Hu, Pablo Alonso-González

Canalized phonon polaritons in twisted van der Waals crystals offer a route to control nanoscale thermal energy flow. Building on the established twisted $\alpha$-MoO${}_3$ trilayer platf…
