questions on how geometry, symmetry, and topology affect physical properties, paving the …

We examine the role of strong nonlinearity on the topologically robust edge state in a one-
dimensional system. We consider a chain inspired from the Su-Schrieffer-Heeger model but …

Despite the extensive studies of topological systems, the experimental characterizations of
strongly nonlinear topological phases have been lagging. To address this shortcoming, we …

Phononic crystals (PnCs) and acoustic metamaterials (AMMs) are artificially architected
materials endowed with the capabilities of wave manipulation. This review specifically …

Concepts from quantum topological states of matter have been extensively utilized in the
past decade to create mechanical metamaterials with topologically protected features, such …

We investigate how Rayleigh waves interact with time-modulated resonators located on the
free surface of a semi-infinite elastic medium. We begin by studying the dynamics of a single …

Higher harmonic generation (HHG) of elastic waves is beneficial for various applications,
including engineering nondestructive testing, imaging, therapy, etc. Due to the ubiquity of …
