Thermodynamic evidence for interaction-driven first-order topological quantum phase transitions
Surajit Dutta, Nadav Auerbach, Chiho Yoon +12
Topological quantum phase transitions in non interacting systems occur through continuous gap closing and reopening. In strongly interacting systems, however, competing ordered sta…
Probing the Potential Profile of Twisted Bilayer Graphene via Fabry-Pérot Interference
Curtis McDowell, Alina MreÅca-KolasiÅska, Kenji Watanabe +3
The paper uses Fabry‑Pérot interference measurements to map the internal potential landscape of large‑angle twisted bilayer graphene, revealing a hidden doped cavity and demonstrat…
Screening-controlled dynamical criticality in the quantum Hall regime
Tanima Chanda, Simrandeep Kaur, Anantbir Virk +5
At continuous electronic phase transitions, Coulomb interactions can modify the relation between length, energy, and temperature, but experimentally disentangling their effects on…
Real-space Imaging of Quantum Hall Quasiparticles
Jinghao Deng, Yiming Sun, Dimitri Pimenov +4
Quantum Hall systems host emergent quasiparticles with unusual charge, spin, and statistics, such as fractionally charged anyons. Although transport measurements have revealed many…
Imaging flat band electron hydrodynamics in biased bilayer graphene
Canxun Zhang, Evgeny Redekop, Hari Stoyanov +12
Hydrodynamic electron transport arises when carrier kinetics are dominated by interelectron collisions rather than the relaxation of momentum out of the electron system. In recent…
Evidence of Metallic Wigner Crystal in Rhombohedral Graphene
Tonghang Han, Jackson P. Butler, Shenyong Ye +15
When the Coulomb interaction dominates over kinetic energy, electrons can crystallize into a Wigner crystal (WC). This paradigmatic correlated electronic phase has been realized in…
