Space-Time Elastic Metamaterials for Zero-Frequency and Zero-Wavenumber Bandgaps
Brahim Lemkalli, Alaa Ali, Qingxiang Ji +5
We create wave-matter space-time metamaterials using optical trapping forces to manipulate mass-spring chains and create zero-frequency and zero-wavenumber band gaps: the bosonic n…
