Phononic topological insulators with tunable pseudospin physics
Yizhou Liu, Yong Xu, Wenhui Duan
Efficient control of phonons is crucial to energy-information technology, but limited by the lacking of tunable degrees of freedom like charge or spin. Here we suggest to utilize c…
Binding a Hopfion in Chiral Magnet Nanodisk
Yizhou Liu, Roger Lake, Jiadong Zang
Hopfions are three-dimensional (3D) topological textures characterized by the integer Hopf invariant . Here, we present the realization of a zero--field, stable hopfion spin t…
Spin superfluid Josephson oscillator
Yizhou Liu, Igor Barsukov, Ilya Krivorotov +2
The magnetic analogue of the Josephson effect can be exploited to develop a new class of nano-spin oscillators that we denote as spin superfluid Josephson oscillators. Such a devic…
Planar Hall effect in antiferromagnetic MnTe thin films
Gen Yin, Jie-Xiang Yu, Yizhou Liu +3
We show that the spin-orbit coupling (SOC) in alpha-MnTe impacts the transport behavior by generating an anisotropic valence-band splitting, resulting in four spin-polarized pocket…
Thermal engineering in low-dimensional quantum devices: a tutorial review of nonequilibrium Green's function methods
Xiaobin Chen, Yizhou Liu, Wenhui Duan
Thermal engineering of quantum devices has attracted much attention since the discovery of quantized thermal conductance of phonons. Although easily submerged in numerous excitatio…
Pseudo Dirac Nodal Sphere: Unusual Electronic Structure and Material Realization
Jianfeng Wang, Yizhou Liu, Kyung-Hwan Jin +4
Topological semimetals (TSMs) in which conduction and valence bands cross at zero-dimensional (0D) Dirac nodal points (DNPs) or 1D Dirac nodal lines (DNLs), in 3D momentum space, h…
