Direct observation of multiband transport in magnonic Penrose quasicrystals via broadband and phase-resolved spectroscopy
INTRODUCTION Since the discovery of quasicrystals over three and a half decades ago (1), their aperiodicity and unconventional rotational symmetries combined with long-range order have baffled physicists and material scientists alike. Recent advances in nanofabrication techniques have allowed researchers to explore the effects of aperiodicity using the materials-by-design approach (2). The prime examples of this […]
