Fermion parity of an Andreev molecule probed by nonlocal Josephson effect
S. Annabi, H. Riechert, K. Watanabe +5
Fermion parity is a fundamental property of superconducting many-body states. Here, we show that the global fermion parity of a delocalized superconducting state can be detected lo…
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…
Interaction-limited conductivity of twisted bilayer graphene revealed by giant terahertz photoresistance
A. L. Shilov, M. Kravtsov, J. Covey +15
Identifying the microscopic processes that limit conductivity is essential for understanding correlated and quantum-critical states in quantum materials. In twisted bilayer graphen…
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…
Probing moire excitons in MoSe2/WSe2 heterobilayers by combined micro-photoluminescence and lateral force microscopy
L. Caussou, H. Moutaabbid, M. Bernard +6
We study interlayer excitons in MoSe2/WSe2 heterobilayers, by combining lateral force microscopy and micro-photoluminescence spectroscopy. This allows us to correlate the spatial p…
Hard and soft phase slips in a Fabry-Pérot quantum Hall interferometer
N. L. Samuelson, L. A. Cohen, W. Wang +5
Quantum Hall Fabry-Pérot interferometers are sensitive to the properties of bulk quasiparticles enclosed by the interferometer loop, with the interference phase containing informa…
