Programmable Wavefunction Dynamics for Topological and Nonlinear Acoustic Control
This talk presents a unified route to topological and nonlinear acoustic control through engineered time-dependent modulation of on-site parameters, couplings, gain/loss, and external driving.
Overview
Programmable acoustic platforms enable a shift from static, structure-defined wave manipulation to protocol-defined control based on a wavefunction description. This talk will focus on two-level system, especially highlight: (i) Two-level dynamical control of topological states: Landau–Zener redistribution combined with measurement-inspired steering and stabilization; (ii) Two- level control combining Bloch-type protocols and nonlinear multistability. Overall, programmable wavefunction dynamics provides a common language to connect topology, measurement, and nonlinearity, offering a scalable framework for reconfigurable wave devices and robust dynamical functionalities.
