Dirac cone spectroscopy of strongly correlated phases in twisted trilayer graphene
Cheng Shen, Patrick J. Ledwith, Kenji Watanabe +4
Mirror-symmetric magic-angle twisted trilayer graphene (MATTG) hosts flat electronic bands close to zero energy, and has been recently shown to exhibit abundant correlated quantum…
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…
Observation of re-entrant correlated insulators and interaction driven Fermi surface reconstructions at one magnetic flux quantum per moiré unit cell in magic-angle twisted bilayer graphene
Ipsita Das, Cheng Shen, Alexandre Jaoui +8
The discovery of flat bands with non-trivial band topology in magic angle twisted bi-layer graphene (MATBG) has provided a unique platform to study strongly correlated phe-nomena i…
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…
High-order minibands and interband Landau level reconstruction in graphene moire superlattice
Xiaobo Lu, Jian Tang, John R. Wallbank +13
The propagation of Dirac fermions in graphene through a long-period periodic potential would result in a band folding together with the emergence of a series of cloned Dirac points…
Correlated states in twisted double bilayer graphene
Cheng Shen, Yanbang Chu, QuanSheng Wu +13
Electron-electron interactions play an important role in graphene and related systems and can induce exotic quantum states, especially in a stacked bilayer with a small twist angle…
Emergence of Frohlich polaron from interlayer electron-phonon coupling in van der Waals heterostructure
Chaoyu Chen, Jose Avila, Shuopei Wang +8
Van der Waals heterostructures, vertical stacks of layered materials, offer newopportunities for novel quantum phenomena which are absent in their constituent components. Here we r…
