Observation of metastable chiral domain walls in a topological magnet

Richen Xiong, Chenxin Qin, Zhaoyu Han +17

The interplay between topology and correlation can give rise to exotic collective excitations. The integer and fractional quantum anomalous Hall (QAH) magnets recently discovered i…

Propagating Collective Spin-valley Modes in Twisted WSe2

Richen Xiong, Yi Guo, Chenxin Qin +15

The emergence of neutral collective modes is a hallmark of correlated quantum phases but is often challenging to probe experimentally. In two-dimensional flatband systems, charge r…

Optical Imaging of Flavor Order in Flat Band Graphene

Tian Xie, Tobias M. Wolf, Siyuan Xu +15

Spin and valley flavor polarization plays a central role in the many-body physics of flat band graphene, with fermi surface reconstructions often accompanied by quantized anomalous…

Tunable exciton valley-pseudospin orders in moiré Bose-Hubbard model

Richen Xiong, Samuel L. Brantly, Kaixiang Su +9

Spin and charge are the two most important degrees of freedom of electrons. Their interplay lies at the heart of numerous strongly correlated phenomena including Hubbard model phys…

Strain tuned magnetotransport of Jeff=1/2 antiferromagnetic Sr2IrO4 thin films

N. Hu, Y. K. Weng, K. Chen +6

In this work, we report observation of strain effect on physical properties of Sr2IrO4 thin films grown on SrTiO3 (001) and LaAlO3 (001) substrates. It is found that the film on La…

Correlated insulator of excitons in WSe2/WS2 moiré superlattices

Richen Xiong, Jacob H. Nie, Samuel L. Brantly +6

A panoply of unconventional electronic states has been observed in moiré superlattices. Engineering similar bosonic phases remains, however, largely unexplored. We report the obser…

Gate-tunability of the superconducting state at the interface

Weiliang Qiao, Yang Ma, Jiaojie Yan +8

The recent discovery of superconducting interfaces in the -based heterostructures is intriguing, since a much higher superconducting critical temperature (TC ~ 2 K) i…

Facet-dependent magnon-polarons in epitaxial ferrimagnetic Fe3O4 thin films

Wenyu Xing, Yang Ma, Yunyan Yao +5

Magnon-polarons are coherently mixed quasiparticles that originate from the strong magnetoelastic coupling of lattice vibrations and spin waves in magnetic-ordered materials. Recen…
