The ideal limit of rhombohedral graphene: Interaction-induced layer-skyrmion lattices and their collective excitations
Tixuan Tan, Patrick J. Ledwith, Trithep Devakul
We introduce an ideal limit of rhombohedral graphene multilayers. In this limit, we show analytically how short-range repulsion stabilizes a layer-pseudospin skyrmion lattice, whic…
Four Moiré materials at One Magic Angle in Helical Quadrilayer Graphene
Manato Fujimoto, Naoto Nakatsuji, Ashvin Vishwanath +1
We introduce helical twisted quadrilayer graphene (HTQG), four graphene sheets rotated by the same small angle, as a versatile and experimentally accessible platform for correlated…
Gradient-based search of quantum phases: discovering unconventional fractional Chern insulators
André Grossi Fonseca, Eric Wang, Sachin Vaidya +3
The discovery and understanding of new quantum phases has time and again transformed both fundamental physics and technology, yet progress often relies on slow, intuition-based the…
Exotic Carriers from Concentrated Topology: Dirac Trions as the Origin of the Missing Spectral Weight in Twisted Bilayer Graphene
Patrick J. Ledwith, Ashvin Vishwanath, Eslam Khalaf
The nature of charge carriers in twisted bilayer graphene (TBG) near , where superconductivity emerges, remains mysterious. While various symmetry-broken ground states have…
Modulation of superconductivity across a Lifshitz transition in alternating-angle twisted quadrilayer graphene
Isabelle Y. Phinney, Andrew Zimmerman, Zeyu Hao +5
We report electric field-controlled modulation of the Fermi surface topology and explore its effects on the superconducting state in alternating-angle twisted quadrilayer graphene…
