Excitonic Mott insulator in a Bose-Fermi-Hubbard system of moiré / heterobilayer
Beini Gao, Daniel G. Suárez-Forero, Supratik Sarkar +13
Understanding the Hubbard model is crucial for investigating various quantum many-body states and its fermionic and bosonic versions have been largely realized separately. Recently…
Magic-Angle Twisted Symmetric Trilayer Graphene as Topological Heavy Fermion Problem
Jiabin Yu, Ming Xie, B. Andrei Bernevig +1
Recently, Ref. [1] reformulated magic-angle twisted bilayer graphene (MATBG) as a topological heavy fermion problem, and used this reformulation to provide a deeper understanding f…
A Two-Kind-Boson Mixture Honeycomb Hamiltonian of Bloch Exciton-Polaritons
Haining Pan, K. Winkler, Mats Powlowski +9
The electronic bandstructure of a solid is a collection of allowed bands separated by forbidden bands, revealing the geometric symmetry of the crystal structures. Comprehensive kno…
Competing zero-field Chern insulators in Superconducting Twisted Bilayer Graphene
Petr Stepanov, Ming Xie, Takashi Taniguchi +5
The discovery of magic angle twisted bilayer graphene (MATBG) has unveiled a rich variety of superconducting, magnetic and topologically nontrivial phases. The existence of all the…
Weak-field Hall Resistivity and Spin/Valley Flavor Symmetry Breaking in Magic-Angle Twisted Bilayer Graphene
Ming Xie, Allan H. MacDonald
Near a magic twist angle, the lowest energy conduction and valence bands of bilayer graphene moiré superlattices become extremely narrow. The band dispersion that remains is sensit…
Terahertz Faraday and Kerr rotation spectroscopy of BiSb films in high magnetic fields up to 30 Tesla
Xinwei Li, Katsumasa Yoshioka, Ming Xie +16
We report results of terahertz Faraday and Kerr rotation spectroscopy measurements on thin films of , an alloy system that exhibits a semimetal-to-top…
Theory of phonon side jump contribution in Anomalous Hall transport
Cong Xiao, Ying Liu, Ming Xie +2
The role of electron-phonon scattering in finite-temperature anomalous Hall effect is still poorly understood. In this work, we present a Boltzmann theory for the side-jump contrib…
Electrical Reservoirs for Bilayer Excitons
Ming Xie, Allan H. MacDonald
The ground state of two-dimensional (2D) electron systems with equal low densities of electrons and holes in nearby layers is an exciton fluid. We show that a reservoir for exciton…
Polariton Supercurrent Generation in Unipolar Electro-optic Devices
Ming Xie, David Snoke, A. H. MacDonald
We describe a mechanism by which an electrical bias voltage applied across a unipolar semiconductor quantum well can drive an exciton or polariton supercurrent. The mechanism depen…
Microscopic Theory of Equilibrium Polariton Condensates
Fei Xue, Fengcheng Wu, Ming Xie +2
We present a microscopic theory of the equilibrium polariton condensate state of a semiconductor quantum well in a planar optical cavity. The theory accounts for the adjustment of…
Optical conductivity of the two-dimensional electron gas
Ming Xie, Guru Khalsa, A. H. MacDonald
Motivated by recent interest in perovskite surfaces and heterostructures, we present an analysis of the Kubo conductivity of a two-dimensional electron gas (2DEG) formed in the $t_…
