New constructions of asymptotically optimal codebooks via character sums over a local ring
Liqin Qian, Xiwang Cao, Wei Lu +1
In this paper, we present explicit description on the additive characters, multiplicative characters and Gauss sums over a local ring. As an application, based on the additive char…
Two constructions of asymptotically optimal codebooks via the trace functions
Xia Wu, Wei Lu, Xiwang Cao +1
In this paper, we present two new constructions of complex codebooks with multiplicative characters, additive characters and trace functions over finite fields, and determine the m…
Transverse instability in the "light sail" ion acceleration
Y. Wan, I. A. Andriyash, W. Lu +2
Acceleration of ultrathin plasma foils by laser radiation pressure promises compact alternatives to the conventional ion accelerators. It was shown, that a major showstopper for su…
Harnessing Intrinsic Noise in Memristor Hopfield Neural Networks for Combinatorial Optimization
Fuxi Cai, Suhas Kumar, Thomas Van Vaerenbergh +8
We describe a hybrid analog-digital computing approach to solve important combinatorial optimization problems that leverages memristors (two-terminal nonvolatile memories). While p…
Palladium Diselenide Long-Wavelength Infrared Photodetector with High Sensitivity and Stability
Mingsheng Long, Yang Wang, Peng Wang +11
A long-wavelength infrared (IR) photodetector based on two-dimensional materials working at room temperature would have wide applications in many aspects in remote sensing, thermal…
Terahertz Probe of Photoexcited Carrier Dynamics in Dirac Semimetal Cd3As2
Wei Lu, Jiwei Ling, Faxian Xiu +1
The relaxation dynamics of photoexcited quasiparticles of three-dimensional (3D) Dirac semimetals are vital towards their application in high performance electronic and optoelectro…
