Ultrafast electron diffractometer with Terahertz-driven pulse compression
Dongfang Zhang, Tobias Kroh, Felix Ritzkowsky +6
Terahertz (THz)-based electron manipulation has recently been shown to hold tremendous promise as a technology for manipulating and driving the next-generation of compact ultrafast…
Data hiding in complex-amplitude modulation using a digital micromirror device
Shuming Jiao, Dongfang Zhang, Chonglei Zhang +3
A digital micromirror device (DMD) is an amplitude-type spatial light modulator. However, a complex-amplitude light modulation with a DMD can be achieved using the superpixel schem…
Cascaded Multi-cycle terahertz driven ultrafast electron acceleration and manipulation
Dongfang Zhang, Moein Fakhari, Huseyin Cankaya +3
Terahertz (THz)-based electron acceleration and manipulation has recently been shown to be feasible and to hold tremendous promise as a technology for the development of next-gener…
Observation of phonon parametric down-conversion in a spherical Bose-Einstein condensate
Tianyou Gao, Jian-Song Pan, Dongfang Zhang +8
We report the observation of parametric down-conversion of phonons in a spherical Bose-Einstein condensate. The spherical symmetry, which is crucial for observing this phenomenon,…
