Strongly coupled ultracompressed self-cavity plasmon polaritons at millikelvin temperatures
Luojia Zhang, Andrew T. Pierce, Xuepeng Wang +7
Van der Waals heterostructures exhibit self-cavity resonances from sub-terahertz to terahertz frequencies and thus offer an attractive route toward realizing cavity-modified phases…
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…
Imaging propagating terahertz collective modes in two-dimensional semiconductor double layers
Andrew T. Pierce, Chirag Vaswani, Dimitri Pimenov +7
Two-dimensional transition metal dichalcogenide (TMD) semiconductors exhibit a wide range of novel phenomena at millielectronvolt (terahertz-frequency) energy scales, including sup…
Strong interactions and isospin symmetry breaking in a supermoiré lattice
Yonglong Xie, Andrew T. Pierce, Jeong Min Park +10
In multilayer moiré heterostructures, the interference of multiple twist angles ubiquitously leads to tunable ultra-long-wavelength patterns known as supermoiré lattices. However,…
Tunable interplay between light and heavy electrons in twisted trilayer graphene
Andrew T. Pierce, Yonglong Xie, Jeong Min Park +5
In strongly interacting systems with multiple energy bands, the interplay between electrons with different effective masses and the enlarged Hilbert space drives intricate correlat…
Field-tuned and zero-field fractional Chern insulators in magic angle graphene
Daniel Parker, Patrick Ledwith, Eslam Khalaf +7
In contrast to the fractional quantum Hall (FQH) effect, where electron density fixes the applied magnetic field, fractional Chern insulators (FCIs) can realize FQH states in compa…
Superconductivity in a quintuple-layer square-planar nickelate

Since the discovery of high-temperature superconductivity in the copper oxide materials, there have been sustained efforts to both understand the origins of this phase and discover…
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…
