Breaking of Time Translation Symmetry and Ergodicity, and Entropy decrease in a Continuous Time Crystal Driven by Nonreciprocal Optical Forces

Autor: Liu, Tongjun, Raskatla, Venugopal, Li, Jinxiang, MacDonald, Kevin F., Zheludev, Nikolay I.

Nonreciprocal nonequilibrium process are attracting growing interest in sociology, animal behaviour, chemistry, and nanotechnology, and may have played a role in the origin of life. It is less widely recognized, however, that in open systems light ca

Continuous Space-Time Crystal State Driven by Nonreciprocal Optical Forces

Autor: Raskatla, Venugopal, Liu, Tongjun, Li, Jinxiang, MacDonald, Kevin F., Zheludev, Nikolay I.

Publikováno v: Phys. Rev. Lett. 133, 136202 (2024)

Continuous time crystals (CTCs) - media with broken continuous time translation symmetry - are an eagerly sought state of matter that spontaneously transition from a time-independent state to one of periodic motion in response to a small perturbation

Optical Control of Nanomechanical Eigenfrequencies and Brownian Motion in Metamaterials

Autor: Li, Jinxiang, MacDonald, Kevin F., Zheludev, Nikolay I.

Publikováno v: Nano Lett. 22, 4301-4306 (2022)

Nanomechanical photonic metamaterials provide a wealth of active switching, nonlinear and enhanced light-matter interaction functionalities by coupling optically and mechanically resonant subsystems. Thermal (Brownian) motion of the nanostructural co
