Fermiology and the Candidate Chiral Superconductor in Rhombohedral Tetralayer Graphene
Sandesh S. Kalantre, Ben H. Alexander, Julian May-Mann +11
Chiral superconductivity, in which the phase of the superconducting order parameter winds in momentum space, has long been sought for its close link to topological superconductivit…
Crystals Caught Doping: Metallic Wigner Crystals in Rhombohedral Graphene
Junkai Dong, Tomohiro Soejima, Daniel E. Parker +1
Nearly a century after Wigner's initial proposal, electron crystals are now a topic of intense experimental and theoretical interest. However, most proposed crystalline phases are…
Quantum Geometry Driven Crystallization: A Neural-Network Variational Monte Carlo Study
Agnes Valenti, Yaar Vituri, Yubo Yang +7
Wigner crystals are a paradigmatic form of interaction driven electronic order. A key open question is how Berry curvature and, more generally, quantum geometry reshape crystalliza…
Beyond the Lowest Landau Level: Unlocking More Robust Fractional States Using Flat Chern Bands with Higher Vortexability
Yitong Zhang, Siddhartha Sarkar, Xiaohan Wan +3
Enhancing the many-body gap of a fractional state is crucial for realizing robust fractional excitations. For fractional Chern insulators, existing studies suggest that making flat…
hBN alignment orientation controls moiré strength in rhombohedral graphene
Matan Uzan, Weifeng Zhi, Matan Bocarsly +11
Rhombohedral multilayer graphene hosts a rich landscape of correlated symmetry-broken phases, driven by strong interactions from its flat band edges. Aligning to hexagonal boron ni…
Topological constraint on crystalline current
Tomohiro Soejima, Junkai Dong, Ophelia Evelyn Sommer +2
How much current does a sliding electron crystal carry? The answer to this simple question has important implications for the dynamic properties of the crystal, such as the frequen…
Phonons in Electron Crystals with Berry Curvature
Junkai Dong, Ophelia Evelyn Sommer, Tomohiro Soejima +2
Recent advances in 2D materials featuring nonzero Berry curvature have inspired extensions of the Wigner crystallization paradigm. This paper derives a low-energy effective theory…
-Jellium Model for the Anomalous Hall Crystal
Tomohiro Soejima, Junkai Dong, Ashvin Vishwanath +1
The jellium model is a paradigmatic problem in condensed matter physics, exhibiting a phase transition between metallic and Wigner crystal phases. However, its vanishing Berry curv…
Imaging Coulomb interactions and migrating Dirac cones in twisted graphene by local quantum oscillations
Matan Bocarsly, Indranil Roy, Vishal Bhardwaj +12
Flat band moiré graphene systems have emerged as a quintessential platform to investigate correlated phases of matter. A plethora of interaction-driven ground states have been prop…
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,…
Anomalous Hall Crystals in Rhombohedral Multilayer Graphene II: General Mechanism and a Minimal Model
Tomohiro Soejima, Junkai Dong, Taige Wang +4
We propose a minimal "three-patch model" for the anomalous Hall crystal (AHC), a topological electronic state that spontaneously breaks both time-reversal symmetry and continuous t…
Higher vortexability: zero field realization of higher Landau levels
Manato Fujimoto, Daniel E. Parker, Junkai Dong +3
The rise of moiré materials has led to experimental realizations of integer and fractional Chern insulators in small or vanishing magnetic fields. At the same time, a set of minima…
