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…
Probing bilayer topological order with layer-resolved transport
Hongquan Liu, J. I. A. Li, D. E. Feldman
Shot noise has been used to measure fractional charges of anyons. The value of the charge imposes constraints on fractional statistics but does not determine it. This issue is part…
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…
Evidence of Momentum Space Condensation in Rhombohedral Hexalayer Graphene
Erin Morissette, Peiyu Qin, K. Watanabe +2
Spontaneous symmetry breaking provides a powerful window into the nature of underlying electronic orders. In strongly correlated systems, multiple symmetry-breaking orders can aris…
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.…
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…
High quality magnetotransport in graphene using the edge-free Corbino geometry
Y. Zeng, J. I. A. Li, S. A. Dietrich +5
We report fabrication of graphene devices in a Corbino geometry consisting of concentric circular electrodes with no physical edge connecting the inner and outer electrodes. High d…
Spin-current probe for phase transition in an insulator
Zhiyong Qiu, Jia Li, Dazhi Hou +9
Spin fluctuation and transition have always been one of central topics of magnetism and condensed matter science. Experimentally, the spin fluctuation is found transcribed onto sca…
