Imaging the vacuum fluctuations of a quantum field
Yansheng Zhang, Feiyang Wang, Yi Jiang +5
Heisenberg uncertainties lead to inevitable fluctuations in the measurement outcomes for quantum-mechanical observables. For quantum fields, these uncertainties result in random sp…
Analog Simulation of Massive Relativistic Quantum Fields in 2 + 1 Dimensions
Yansheng Zhang, Feiyang Wang, Paul H. C. Wong +8
Quantum field theories provide fundamental models of complex interacting systems, from high-energy physics and cosmology to condensed matter. However, solving these models in non-p…
Suppression and enhancement of bosonic stimulation by atomic interactions
Konstantinos Konstantinou, Yansheng Zhang, Paul H. C. Wong +7
The tendency of identical bosons to bunch, seen in the Hanbury Brown-Twiss effect and Bose-Einstein condensation, is a hallmark of quantum statistics. This bunching can enhance the…
Energy-space random walk in a driven disordered Bose gas
Yansheng Zhang, Gevorg Martirosyan, Christopher J. Ho +3
Motivated by the experimental observation [1] that driving a non-interacting Bose gas in a 3D box with weak disorder leads to power-law energy growth, with $η=0.46(…
