Spin and Orbital Angular Momentum Polarization in Thouless Topological Charge Pumping
Esmaeil Taghizadeh Sisakht, Uiseok Jeong, Xiao jiang +4
Quantized charge pumping in one-dimensional chiral wires has been widely studied in the context of topological physics in a (1+1)-dimensional synthetic space, yet the role of orbit…
Phonon Spin Selective One-Way Axial Phonon Transport in Chiral Nanohelix
Jia Li, Yu-Tao Tan, Yizhou Liu +1
Selectively exciting and manipulating phonons at nanoscale becomes more and more important but still remains challenging in modern nano-energy control and information sensing. Here…
Photomagnetic-Chiral Anisotropy mediated by Chirality-Driven Asymmetric Spin Splitting
Tianwei Ouyang, Hang Su, Wanning Zhang +4
Photomagnetic effects (PMEs), intrinsic to transition metals, arises from the interaction between light-induced angular momentum and electronic spin. These effects are suppressed i…
Collective Interference of Phonon Spin and Dipole Moment Rotation Induced Circular Dichroism
Yizhou Liu, Yu-Tao Tan, Dapeng Liu +1
The classical field description of phonon spin relies on the invariance of a continuous elastic field under infinitesimal rotation. However, a local medium element in the continuou…
Advances in Phonons: From Band Topology to Phonon Chirality
Tiantian Zhang, Yizhou Liu, Hu Miao +1
Phonons, the quantized collective vibrations of a crystal lattice, are among the most fundamental bosonic excitations in condensed matter systems. They govern thermal transport, me…
Construction of Hopfion Crystals
Wen-Tao Hou, Zhuoxian Xiang, Yizhou Liu +1
Hopfions, three-dimensional topological solitons characterized by nontrivial Hopf indices, represent a fundamental class of field configurations that emerge across diverse areas of…
