Magnetic field-induced quantum phase transitions in a van der Waals magnet
Siwen Li, Zhipeng Ye, Xiangpeng Luo +10
Exploring new parameter regimes to realize and control novel phases of matter has been a main theme in modern condensed matter physics research. The recent discovery of 2D magnetis…
Observation of a ferro-rotational order coupled with second-order nonlinear optical fields
Wencan Jin, Elizabeth Drueke, Siwen Li +6
The ferro-rotational order, whose order parameter (OP) is an axial vector invariant under both time reversal (TR) and spatial inversion (SI) operations, is the last remaining categ…
Evolution of interlayer and intralayer magnetism in three atomically thin chromium trihalides
Hyun Ho Kim, Bowen Yang, Siwen Li +16
We conduct a comprehensive study of three different magnetic semiconductors, CrI, CrBr, and CrCl, by incorporating both few- and bi-layer samples in van der Waals tunne…
Edge Modes and Asymmetric Wave Transport in Topological Lattices: Experimental Characterization at Finite Frequencies
Jihong Ma, Di Zhou, Kai Sun +2
Although topological mechanical metamaterials have been extensively studied from a theoretical perspective, their experimental characterization has been lagging. To address this sh…
