Coexisting Charge Density Wave and Superconducting Order in Quantizing Magnetic Fields
Ron Q. Nguyen, Peiyu Qin, Hai-Tian Wu +12
Charge density wave (CDW) and superconductivity are both common in strongly interacting electron systems. While CDW order is ubiquitous in both quantum Hall systems and unconventio…
Continuously tunable dipolar exciton geometry for controlling bosonic quantum phase transitions
Zhenyu Sun, Haoteng Sun, Xiaohang Jia +12
The geometry and binding energy of excitons, set by electron-hole wavefunction distributions, are fundamental factors that underpin their many-body interactions and determine optoe…
A Hierarchy of Superconductivity and Topological Charge Density Wave States in Rhombohedral Graphene
Ron Q. Nguyen, Hai-Tian Wu, Erin Morissette +7
Superconductivity and the quantum Hall effect are conventionally regarded as mutually exclusive: superconductivity is suppressed by magnetic fields, whereas the quantum Hall effect…
Stripe Order in the Metallic and Superconducting Phases of Rhombohedral Hexalayer Graphene
Peiyu Qin, Hai-Tian Wu, Ron Q. Nguyen +5
In strongly correlated electronic systems, Coulomb interactions frequently give rise to emergent electronic orders that spontaneously break rotational symmetry. Understanding how s…
Angular Interplay of Nematicity, Superconductivity, and Strange Metallicity in a Moiré Flat Band
Naiyuan J. Zhang, Pavel A. Nosov, Ophelia Evelyn Sommer +5
Superconductivity in strongly correlated electron systems frequently exhibits broken rotational symmetry, raising fundamental questions about the underlying order parameter symmetr…
Observation of giant nonlinear Hall conductivity in Bernal bilayer graphene
Dmitry V. Chichinadze, Naiyuan James Zhang, Jiang-Xiazi Lin +6
In a system of two-dimensional electrons, a combination of broken symmetry, interactions, and nontrivial topology can conspire to give rise to a nonlinear transport regime, where e…
Bilayer Excitons in the Laughlin Fractional Quantum Hall State
Ron Q. Nguyen, Naiyuan J. Zhang, Navketan Khurana-Batra +6
The Laughlin state embodies a universal class of fractional quantum Hall effects arising in two-dimensional electron systems subjected to strong perpendicular magnetic fields. Conv…
Excitons in the Fractional Quantum Hall Effect
Naiyuan J. Zhang, Ron Q. Nguyen, Navketan Batra +5
Excitons, Coulomb-driven bound states of electrons and holes, are typically composed of integer charges. However, in bilayer systems influenced by charge fractionalization, a more…
Evidence for a Superfluid-to-solid Transition of Bilayer Excitons
Yihang Zeng, Dihao Sun, Naiyuan J. Zhang +8
One of the most spectacular properties associated with Bose-Einstein condensation (BEC) is superfluidity in which the system exhibits zero viscosity and flows without dissipation.…
Spontaneous momentum polarization and diodicity in Bernal bilayer graphene
Jiang-Xiazi Lin, Yibang Wang, Naiyuan J. Zhang +4
The low-temperature phase diagram of multilayer graphene heterostructures is largely defined by the exchange-driven instability that lifts the four-fold isospin degeneracy. Such in…
Angle-resolved transport nonreciprocity and spontaneous symmetry breaking in twisted trilayer graphene
Naiyuan James Zhang, Jiang-Xiazi Lin, Dmitry V. Chichinadze +5
The ability to identify and characterize spontaneous symmetry breaking is central to our understanding of 2D materials with strong correlation, such as the moiré flat bands in magi…
Coulomb screening and thermodynamic measurements in magic-angle twisted trilayer graphene
Xiaoxue Liu, Naiyuan James Zhang, K. Watanabe +2
The discovery of magic-angle twisted trilayer graphene (tTLG) adds a new twist to the family of graphene moiré. The additional graphene layer unlocks a series of intriguing propert…
