Observation of the dual quantum spin Hall insulator by density-tuned correlations in a van der Waals monolayer
Jian Tang, Thomas Siyuan Ding, Hongyu Chen +25
The convergence of topology and correlations represents a highly coveted realm in the pursuit of novel quantum states of matter. Introducing electron correlations to a quantum spin…
Sliding ferroelectric memories and synapses
Xiuzhen Li, Biao Qin, Yaxian Wang +19
Ferroelectric materials with switchable electric polarization hold great promise for a plethora of emergent applications, such as post-Moore's law nanoelectronics, beyond-Boltzmann…
Isospin competitions and valley polarized correlated insulators in twisted double bilayer graphene
Le Liu, Shihao Zhang, Yanbang Chu +13
New phase of matter usually emerges when a given symmetry breaks spontaneously, which can involve charge, spin, and valley degree of freedoms. Here, we report an observation of new…
Optically and magnetically addressable valley pseudospin of interlayer excitons in bilayer MoS2
Yanchong Zhao, Luojun Du, Shiqi Yang +13
Interlayer valley excitons in bilayer MoS2 feature concurrently large oscillator strength and long lifetime, and hence represent an advantageous scenario for valleytronic applicati…
Temperature-linear Resistivity in Twisted Double Bilayer Graphene
Yanbang Chu, Le Liu, Cheng Shen +13
We report an experimental study of carrier density (n), displacement field (D) and twist angle (θ) dependence of temperature (T)-linear resistivity in twisted double bilayer graphe…
Emergence of Chern insulating states in non-Magic angle twisted bilayer graphene
Cheng Shen, Jianghua Ying, Le Liu +14
Twisting two layers into a magic angle (MA) of ~1.1° is found essential to create low energy flat bands and the resulting correlated insulating, superconducting, and magnetic phase…
