Substrate-free THz focal plane metamaterial array with high absorption ratio
Zhigang Li, Yi Ou, Xubiao Peng +4
Microelectromechanical system (MEMS) focal plane array (FPA) with optical readout offers exciting opportunities for real-time terahertz (THz) imaging. However, conventional FPA suf…
Rotation by shape change, autonomous molecular motors and effective timecrystalline dynamics
Xubiao Peng, Jin Dai, Antti J. Niemi
A deformable body can rotate even with no angular momentum, simply by changing its shape. A good example is a falling cat, how it maneuvers in air to land on its feet. Here a first…
Classical Hamiltonian Time Crystals -- General Theory And Simple Examples
Jin Dai, Antti J. Niemi, Xubiao Peng
We focus on a Hamiltonian system with a continuous symmetry, and dynamics that takes place on a presymplectic manifold. We explain how the symmetry can become spontaneously broken…
The photon vortex beam in rotating medium
Jianye Wei, Wei Jia, Xubiao Peng +1
In this paper we consider the photon vortex beam in the rotating medium, where the rotating velocity acts as an effective vector potential. Using the Riemann-Silberstein vector, we…
Topologically enhanced time crystals and molecular knots
Jin Dai, Xubiao Peng, Antti J. Niemi
A time crystal is a time dependent physical system that does not reach a standstill, even in state of minimum energy. Here we show that the stability of a time crystal can be enhan…
Improvement in corrosion resistance and biocompatibility of AZ31 magnesium alloy by NH+2 ions
Xian Wei, Zhicheng Li, Pinduo Liu +4
Magnesium alloys have been considered to be favorable biodegradable metallic materials used in orthopedic and cardiovascular applications. We introduce NH+2 to the AZ31 Mg alloy su…
