Research on the knee region of cosmic ray by using a novel type of electron–neutron detector array
By accurately measuring composition and energy spectrum of cosmic ray, the origin problem of so called “knee” region (energy >one PeV) can be solved. However, up to the present, the results of the spectrum in ...

Bogoliubov quasiparticle on the gossamer Fermi surface in electron-doped cuprates
Electron-doped cuprates consistently exhibit strong antiferromagnetic correlations, leading to the prevalent belief that antiferromagnetic spin fluctuations mediate Cooper pairing in these unconventional super...

Manipulation of spin filtering effect in a hybrid magnetic–electric-barrier nanostructure with a δ-do**
By means of a hybrid magnetic–electric barrier (MEB) on the top of the semiconductor InAs/AlxIn1−xAs heterostructure, a spin filter can be obtained. In this work, we introduce a δ-do** into this MEB device by m...

Acoustic topological insulator and robust one-way sound transport
The acoustic analogue of a topological insulator is shown: a metamaterial exhibiting one-way sound transport along its edge. The system — a graphene-like array of stainless-steel rods — is a promising new plat...

Introduction to the CDEX experiment
It is believed that weakly interacting massive particles (WIMPs) are candidates for dark matter (DM) in our universe which come from outer space and might interact with the standard model (SM) matter of our de...
