ActICL: Post-Training for Agentic Multimodal In-Context Learning
Yanshu Li, Ruixiang Tang, Junyi Jessy Li +1
Multimodal in-context learning (ICL) is an important capability of multimodal large language models (MLLMs). Its performance is closely tied to the demonstrations it uses, making d…
Twist-configured moire-moire reconstruction governs diverse commensurate double-moire phases in twisted bilayer graphene on h-BN
Yuta Seo, Naoto Nakatsuji, Jimpei Kawase +6
The coexistence of multiple moire lattices in van der Waals heterostructures raises a fundamental question: how do distinct moire patterns interact and reconstruct? Here, we invest…
One-Dimensional Electronic States in a Moiré Superlattice of Twisted Bilayer WTe2
Takuto Kawakami, Hayato Tateish, Daiki Yoshida +10
One-dimensional (1D) moiré superlattices provide a new route to engineering reduced-dimensional electronic states in van der Waals materials, yet their electronic structure and mic…
High-throughput discovery of moiré homobilayers guided by topology and energetics
Naoto Nakatsuji, Jennifer Cano, Valentin Crépel
Van der Waals heterostructures promise on-demand designer quantum phases through control of monolayer composition, stacking, twist angle, and external fields. Yet, experimental eff…
Emergent electronic insulating states in a one-dimensional moiré superlattice
Jianfeng Bi, Masaki Minamikawa, Ruige Dong +11
Two-dimensional (2D) van der Waals (vdW) moiré superlattices have provided a powerful knob to engineer a plethora of new quantum states. However, extending such moiré engineering t…

We study the structural relaxation and electronic properties of a one-dimensional (1D) moiré system composed of a zigzag graphene nanoribbon (GNR) placed on a hexagonal boron nitri…
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…
Moiré Band Engineering in Twisted Trilayer WSe2

We present a systematic theoretical study on the structural and electronic properties of twisted trilayer transition metal dichalcogenide (TMD) WSe, where two independent moiré…
Manipulating moires by controlling heterostrain in van der Waals devices
Ian Sequeira, Andrew Z. Barabas, Aaron H Barajas-Aguilar +6
Van der Waals (vdW) moires offer tunable superlattices that can strongly manipulate electronic properties. We demonstrate the in-situ manipulation of moire superlattices via hetero…
Multi-scale lattice relaxation in general twisted trilayer graphenes
Naoto Nakatsuji, Takuto Kawakami, Mikito Koshino
We present comprehensive theoretical studies on the lattice relaxation and the electronic structures in general non-symemtric twisted trilayer graphenes. By using an effective cont…
