Field-tuned and zero-field fractional Chern insulators in magic angle graphene
Daniel Parker, Patrick Ledwith, Eslam Khalaf +7
In contrast to the fractional quantum Hall (FQH) effect, where electron density fixes the applied magnetic field, fractional Chern insulators (FCIs) can realize FQH states in compa…
Efficient Simulation of Dynamics in Two-Dimensional Quantum Spin Systems with Isometric Tensor Networks
Sheng-Hsuan Lin, Michael Zaletel, Frank Pollmann
We investigate the computational power of the recently introduced class of isometric tensor network states (isoTNSs), which generalizes the isometric conditions of the canonical fo…
Detecting symmetry breaking in magic angle graphene using scanning tunneling microscopy
Jung Pyo Hong, Tomohiro Soejima, Michael P. Zaletel
A growing body of experimental work suggests that magic angle twisted bilayer graphene exhibits a "cascade" of spontaneous symmetry breaking transitions, sparking interest in the p…
A universal tripartite entanglement signature of ungappable edge states
Karthik Siva, Yijian Zou, Tomohiro Soejima +2
Gapped two-dimensional topological phases can feature ungappable edge states which are robust even in the absence of protecting symmetries. In this work we show that a multipartite…
Absolutely stable time crystals at finite temperature
Francisco Machado, Quntao Zhuang, Norman Y. Yao +1
We show that locally-interacting, periodically-driven (Floquet) Hamiltonian dynamics coupled to a Langevin bath support finite-temperature discrete time crystals (DTC) with an infi…
Visualizing Broken Symmetry and Topological Defects in a Quantum Hall Ferromagnet
Xiaomeng Liu, Gelareh Farahi, Cheng-Li Chiu +5
The interaction between electrons in graphene under high magnetic fields drives the formation of a rich set of quantum Hall ferromagnetic phases (QHFM), with broken spin or valley…
Inter-valley coherent order and isospin fluctuation mediated superconductivity in rhombohedral trilayer graphene
Shubhayu Chatterjee, Taige Wang, Erez Berg +1
Superconductivity was recently discovered in rhombohedral trilayer graphene (RTG) in the absence of a moiré potential. Superconductivity is observed proximate to a metallic state w…
Correlated interlayer exciton insulator in double layers of monolayer WSe2 and moiré WS2/WSe2
Zuocheng Zhang, Emma C. Regan, Danqing Wang +11
Moiré superlattices in van der Waals heterostructures have emerged as a powerful tool for engineering novel quantum phenomena. Here we report the observation of a correlated interl…
Kekulé spiral order at all nonzero integer fillings in twisted bilayer graphene
Yves H. Kwan, Glenn Wagner, Tomohiro Soejima +4
We study magic angle graphene in the presence of both strain and particle-hole symmetry breaking due to non-local inter-layer tunneling. We perform a self-consistent Hartree-Fock s…
Topological charge density waves at half-integer filling of a moiré superlattice
Hryhoriy Polshyn, Yuxuan Zhang, Manish A. Kumar +7
At partial filling of a flat band, strong electronic interactions may favor gapped states harboring emergent topology with quantized Hall conductivity. Emergent topological states…
Strong-Magnetic-Field Magnon Transport in Monolayer Graphene
Haoxin Zhou, Chunli Huang, Nemin Wei +6
At high magnetic fields, monolayer graphene hosts competing phases distinguished by their breaking of the approximate SU(4) isospin symmetry. Recent experiments have observed an ev…
