Photonic Metamaterial Analogue of a Continuous Time Crystal
Tongjun Liu, Jun-Yu Ou, Kevin F. MacDonald +1
Time crystals are an eagerly sought phase of matter with broken time-translation symmetry. Quantum time crystals with discretely broken time-translation symmetry have been demonstr…
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…
