Breaking of Time Translation Symmetry and Ergodicity, and Entropy decrease in a Continuous Time Crystal Driven by Nonreciprocal Optical Forces
Tongjun Liu, Venugopal Raskatla, Jinxiang Li +2
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…
Continuous Space-Time Crystal State Driven by Nonreciprocal Optical Forces
Venugopal Raskatla, Tongjun Liu, Jinxiang Li +2
Continuous time crystals (CTCs) - media with broken continuous time translation symmetry - are an eagerly sought state of matter that spontaneously transition from a time-independe…
Ballistic Dynamics of Flexural Thermal Movements in a Nano-membrane Revealed with Subatomic Resolution
Tongjun Liu, Jun-Yu Ou, Nikitas Papasimakis +3
Flexural oscillations of free-standing films, nano-membranes and nano-wires are attracting growing attention for their importance to the thermal, electrical and mechanical properti…
Picophotonics -- Subatomic Optical Localization Beyond Thermal Fluctuations
Tongjun Liu, Cheng-Hung Chi, Jun-Yu Ou +4
Despite recent tremendous progress in optical imaging and metrology, the resolution gap between atomic scale transmission electron microscopy and optical techniques has not been cl…
Hyperspectral Nanomotion Microscopy
Tongjun Liu, Jun-Yu Ou, Kevin F. MacDonald +1
We have developed a technique that extends static scanning electron microscopic imaging to include hyperspectral mapping of fast thermal and externally-driven movements at up to Me…
