Moiré Topology in Twisted Structures with Noncollinear Spin-Orbit Coupling
Xilong Xu, Liangtao Peng, Shaffique Adam +1
Moiré superlattices provide a powerful platform for flat bands and correlated topological phases, yet most established examples rely on valley-contrasting Berry curvature in hexago…
High-Density Horizontal Arrays of Single-Chirality Carbon Nanotubes
Yanzhao Liu, Zilong Qiu, Yuguang Chen +18
Highly ordered high-density arrays of single-chirality single-walled carbon nanotubes (SWCNTs) are greatly desired for exploring the intrinsic anisotropic properties and collective…
Lattice Relaxation in Moiré Heterobilayers
Christophe De Beule, Yiyang Lai, Liangtao Peng +2
We develop an analytical theory for lattice relaxation in twisted moiré heterobilayers, accounting for lattice mismatch, twist, external biaxial heterostrain, and different elastic…
Disorder-induced symmetry breaking in moiré bands of marginally twisted bilayer MoS
Pablo Reséndiz-Vázquez, Christophe de Beule, Thi-Hai-Yen Vu +8
Twisted transition-metal dichalcogenides host highly tunable moiré potentials, flat bands, and correlated electronic phases, yet the role of disorder in shaping these emergent prop…
Role of electron-electron interactions in -valley twisted transition metal dichalcogenides
Christophe De Beule, Liangtao Peng, E. J. Mele +1
We investigate the role of long-range Coulomb interactions in -valley moirés using the self-consistent Hartree-Fock approximation. This platform was recently proposed [Nature 64…
Theory for Lattice Relaxation in Marginal Twist Moirés
Christophe De Beule, Gayani N. Pallewela, Mohammed M. Al Ezzi +3
Atomically thin moiré materials behave like elastic membranes where at very small twist angles, the van der Waals adhesion energy much exceeds the strain energy. In this ``marginal…
Itinerant Magnetism in Twisted Bilayer WSe and MoTe
Liangtao Peng, Christophe De Beule, Yiyang Lai +4
Using a self-consistent Hartree-Fock theory, we show that the recently observed ferromagnetism in twisted bilayer WSe [Nat. Commun. 16, 1959 (2025)] can be understood as a Ston…
Many-body perturbation theory for moiré systems
Liangtao Peng, Giovanni Vignale, Shaffique Adam
Moiré systems such as magic-angle twisted bilayer graphene have attracted significant attention due to their ability to host correlated phenomena including superconductivity and st…
Coulomb screening of superconductivity in magic-angle twisted bilayer graphene
Julien Barrier, Liangtao Peng, Shuigang Xu +7
The origin of superconductivity in magic-angle twisted bilayer graphene has been a subject of intense debate. While some experimental evidence indicated an unconventional pairing m…
Imaging the Sub-Moiré Potential Landscape using an Atomic Single Electron Transistor
Dahlia R. Klein, Uri Zondiner, Amit Keren +10
Electrons in solids owe their properties to the periodic potential landscapes they experience. The advent of moiré lattices has revolutionized our ability to engineer such landscap…
A self-consistent Hartree theory for lattice-relaxed magic-angle twisted bilayer graphene
Mohammed M. Al Ezzi, Liangtao Peng, Zhengyu Liu +4
For twisted bilayer graphene close to magic angle, we show that the effects of lattice relaxation and the Hartree interaction both become simultaneously important. Including both e…
Theoretical determination of the effect of a screening gate on plasmon-induced superconductivity in twisted bilayer graphene
Liangtao Peng, Indra Yudhistira, Giovanni Vignale +1
The microscopic pairing mechanism for superconductivity in magic-angle twisted bilayer graphene remains an open question. Recent experimental studies seem to rule out a purely elec…
High conductivity from cross-band electron pairing in flat-band systems
Maxim Trushin, Liangtao Peng, Gargee Sharma +2
Electrons in condensed matter may transition into a variety of broken-symmetry phase states due to electron-electron interactions. Applying diverse mean-field approximations to the…
Characterizing the Bulk-Boundary Correspondence of one-dimensional non-Hermitian interacting systems by edge entanglement entropy
Weitao Chen, Liangtao Peng, Hantao Lu +1
Dramatically different from the Hermitian systems, the conventional Bulk-Boundary Correspondence (BBC) is broken in the non-Hermitian systems. In this article, we use edge entangle…
Instability dynamics of nonlinear normal modes in the Fermi-Pasta-Ulam-Tsingou chains
Liangtao Peng, Weicheng Fu, Yong Zhang +1
Nonlinear normal modes are periodic orbits that survive in nonlinear chains, whose instability plays a crucial role in the dynamics of many-body Hamiltonian systems toward thermali…
