Realization of a transition between type-I and type-II Dirac semimetals in monolayers
Yuee Xie, Yujiao Kang, Xiaohong Yan +1
The phase transition between type-I and type-II Dirac semimetals will reveal a series of significant physical properties because of their completely distinct electronic, optical an…
Isolated flat bands in an interlocking-circles lattice
Siwen Li, Yuee Xie, Yuanping Chen
Flat-band physics has attracted much attention in recently years because of its interesting properties and important applications. Some typical lattices have been proposed to gener…
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…
