Programmable Elastic Wave Control Via Mechanical‐Acoustic Interaction in Bistable Metamaterials
Advanced Science, EarlyView.A mechanically programmable metamaterial based on mechanical‐acoustic interaction enables reconfigurable elastic wave control through bistable state switching. Spatial encoding of peak and valley states tunes band structures and transmission, achieving low‐frequency vibration suppression, waveguiding, and energy localization.

Optical bistability in shape-memory nanowire metamaterial array
Applied Physics Letters, 2018 Non-volatile temperature-induced structural phase transitions such as those found in chalcogenide glasses are known to lead to strong changes in optical properties and are widely used in rewritable optical disk technology.

Nonsecular terms in optical bistability
, 2012 We investigate the influence of the nonsecular terms on the optical bistability in a photonic-crystal single-atom laser. The nonsecular terms result in a significant reduction of the bistability threshold.

Interacting Parallel Fluidic Hysterons
Advanced Science, EarlyView.The parallel coupling of fluidic hysterons is introduced, establishing advanced functionalities in inflatable soft systems. A pressure–volume framework reveals how preset volumes Δv∗${\Delta }v^*$ tune nonlinear interactions between hysterons and actuation sequences without changing architecture. Experiments validate the predictions, opening new routes

Single photon optical bistability
, 2023 We investigate the bistability in a small Fabry-Perot interferometer (FPI) with the optical wavelength size cavity, the nonlinear Kerr medium and only a few photons, on average, excited by the external quantum field.

Optical bistability in graphene-wrapped dielectric nanowires.
Optics Express, 2017 We study the optical bistability of graphene-wrapped dielectric cylinders with Kerr-type nonlinear response within the framework of both nonlinear full-wave scattering theory and nonlinear quasistatic theory.

Whispering gallery modes in semiconductor optical fibres and optical bottle microresonators
We explore the optical properties of whispering gallery modes (WGMs) in silicon optical fibres and optical bottle microresonators. In particular, a pump-probe technique is used to experimentally demonstrate thermally induced all-optical modulation.
