Anisotropy of Antiferromagnetic Domains in a Spin-orbit Mott Insulator
Longlong Wu, Wei Wang, Tadesse A. Assefa +9
The temperature-dependent behavior of magnetic domains plays an essential role in the magnetic properties of materials, leading to widespread applications. However, experimental me…
Abnormal topological refraction into free medium at sub-wavelength scale in valley phononic crystal plates
Linyun Yang, Kaiping Yu, Bernard Bonello +2
In this work we propose a topological valley phononic crystal plate and we extensively investigate the refraction of valley modes into the surrounding homogeneous medium. This phon…
Polarization-dependent and Valley-protected Lamb Waves in Asymmetric Pillared Phononic Crystals
Wei Wang, Bernard Bonello, Bahram Djafari-Rouhani +1
We present the realization of the topological valley-protected zero-order antisymmetric (A0) or symmetric (S0) and zero-order shear-horizontal (SH0) Lamb waves at different domain…
Valley and pseudospin-valley topologically protected edge states in symmetric pillared phononic crystals
Wei Wang, Bernard Bonello, Bahram Djafari-Rouhani +1
We present a symmetric double-sided pillared phononic crystals (PPnCs) that can emulate both quantum spin Hall effect (QSHE) and quantum valley Hall effect (QVHE) by solely imposin…
Exploring rotational resonance in elastic metamaterial plates to realize doubly negative property
Wei Wang, Bernard Bonello, Bahram Djafari-Rouhani +2
We report the realization of simultaneously negative effective mass density and shear modulus in a single-phase asymmetric double-sided pillared metamaterial. The negative effectiv…
Half-metallic ferromagnetism in transition-metal doped germanium nitride: A first-principles study
Sheng-Li Zhang, Wei Wang, Er-Hu Zhang
The electronic and magnetic properties of transition-metal doped -Ge3N4 have been studied using first-principles calculations. The results show that the substitutional transitio…
