Semiconductor-based selective emitter with sharp cutoff for thermophotovoltaic energy conversion
Qing Ni, Rajagopalan Ramesh, Cheng-An Chen +1
Semiconductor emitter can possibly achieve sharp cutoff wavelength due to its intrinsic bandgap absorption and almost zero sub-bandgap emission without doping. A germanium wafer ba…

Observation of scale invariance in two-dimensional matter-wave Townes solitons
Cheng-An Chen, Chen-Lung Hung
We report near-deterministic generation of two-dimensional (2D) matter-wave Townes solitons, and a precision test on scale invariance in attractive 2D Boses gases. We induce a shap…

Observation of quasiparticle pair-production and quantum entanglement in atomic quantum gases quenched to an attractive interaction
Cheng-An Chen, Sergei Khlebnikov, Chen-Lung Hung
We report observation of quasiparticle pair-production and characterize quantum entanglement created by a modulational instability in an atomic superfluid. By quenching the atomic…
