Probing spin order via magnon transmission across quantum Hall ferromagnet heterojunctions
Seung Hwan Lee, Shaowen Chen, Andrew T. Pierce +4
Two-dimensional material platforms now host a remarkable array of exotic correlated phases, from unconventional superconductivity to fractional Chern insulators. Probing magnetic o…
Fractional Chern insulators in magic-angle twisted bilayer graphene
Yonglong Xie, Andrew T. Pierce, Jeong Min Park +12
Fractional Chern insulators (FCIs) are lattice analogues of fractional quantum Hall states that may provide a new avenue toward manipulating non-abelian excitations. Early theoreti…
Thermodynamics of free and bound magnons in graphene
Andrew T. Pierce, Yonglong Xie, Seung Hwan Lee +6
Symmetry-broken electronic phases support neutral collective excitations. For example, monolayer graphene in the quantum Hall regime hosts a nearly ideal ferromagnetic phase at fil…
Unconventional sequence of correlated Chern insulators in magic-angle twisted bilayer graphene
Andrew T. Pierce, Yonglong Xie, Jeong Min Park +11
The interplay between strong electron-electron interactions and band topology can lead to novel electronic states that spontaneously break symmetries. The discovery of flat bands i…
Imaging electric field dynamics with graphene optoelectronics
Jason Horng, Halleh B. Balch, Allister F. McGuire +5
The use of electric fields for signalling and control in liquids is widespread, spanning bioelectric activity in cells to electrical manipulation of microstructures in lab-on-a-chi…
A quantum pathway to overcome the trilemma of magnetic data storage
Patrick Robert Forrester, François Patthey, Edgar Fernandes +3
The three essential pillars of magnetic data storage devices are readability, writeability, and stability. However, these requirements compete as magnetic domain sizes reach the fu…
Upgrade of a low-temperature scanning tunneling microscope for electron-spin resonance
Fabian D. Natterer, François Patthey, Tobias Bilgeri +3
Electron spin resonance with a scanning tunneling microscope (ESR-STM) combines the high energy resolution of spin resonance spectroscopy with the atomic scale control and spatial…
Antiferromagnetic MnNi tips for spin-polarized scanning probe microscopy
P. R. Forrester, T. Bilgeri, F. Patthey +2
Spin-polarized scanning tunneling microscopy (SP-STM) measures tunnel magnetoresistance (TMR) with atomic resolution. While various methods for achieving SP probes have been develo…
