Single anyons and anyon binding in a quantum Hall dot
Marco Valentini, Will Wang, Amir Shapour Mohammadi +10
Anyons are particles with quantized fractional statistics. In theory, a single anyon can be stabilized as a localized fractional charge within the bulk of a topologically ordered t…
Finite-momentum Cooper plasmons in superconducting terahertz microcavities
Alex M. Potts, Marios H. Michael, Gunda Kipp +12
The phase mode of a superconductor's order parameter encodes fundamental information about pairing and dissipation, but is typically inaccessible at low frequencies due to the Ande…
Flat band surface state superconductivity in thick rhombohedral graphene
Yi Guo, Owen I. Sheekey, Trevor Arp +11
Rhombohedral multilayer graphene has recently emerged as a rich platform for studying correlation driven magnetic, topological and superconducting states. While most experimental e…
Visualizing interaction-driven restructuring of quantum Hall edge states
Jiachen Yu, Haotan Han, Kristina G. Wolinski +10
Many topological phases host gapless boundary modes that can be dramatically modified by electronic interactions. Even for the long-studied edge modes of quantum Hall phases, formi…
3D microwave imaging of a van der Waals heterostructure
Leonard W. Cao, Chen Wu, Lingyuan Lyu +9
Van der Waals (vdW) heterostructures offer a tunable platform for the realization of emergent phenomena in layered electron systems. While scanning probe microscopy techniques have…
Propagating Collective Spin-valley Modes in Twisted WSe2
Richen Xiong, Yi Guo, Chenxin Qin +15
The emergence of neutral collective modes is a hallmark of correlated quantum phases but is often challenging to probe experimentally. In two-dimensional flatband systems, charge r…

Magic-angle twisted multilayer graphene stands out as a highly tunable class of moiré materials that exhibit strong electronic correlations and robust superconductivity. However, u…
Nanoscale infrared and microwave imaging of stacking faults in multilayer graphene
Ludwig Holleis, Liam Cohen, Noah Samuelson +14
Graphite occurs in a range of metastable stacking orders characterized by both the number and direction of shifts between adjacent layers by the length of a single carbon-carbon bo…
Entropy of strongly correlated electrons in a partially filled Landau level
Alexandre Assouline, Taige Wang, Heun Mo Yoo +7
We use high-resolution chemical potential measurements to extract the entropy of monolayer and bilayer graphene in the quantum Hall regime via the Maxwell relation $\left.\frac{dμ}…

Caitlin L. Patterson, Owen I. Sheekey, Trevor B. Arp +15
Graphene and transition metal dichalcogenide flat-band systems show similar phase diagrams, replete with magnetic and superconducting phases. An abiding question has been whether m…
Superconductivity and quantized anomalous Hall in rhombohedral graphene
Youngjoon Choi, Ysun Choi, Marco Valentini +8
Inducing superconducting correlations in chiral edge states is predicted to generate topologically protected zero energy modes with exotic quantum statistics. Experimental efforts…
Fluctuating magnetism and Pomeranchuk effect in multilayer graphene
