Edge zeros and boundary spinons in topological Mott insulators
Niklas Wagner, Daniele Guerci, Andrew J. Millis +1
We introduce a real-space slave rotor theory of the physics of topological Mott insulators, using the Kane-Mele-Hubbard model as an example, and use it to show that a topological g…
Absence of quantization in the circular photogalvanic effect in disordered chiral Weyl semimetals
Ang-Kun Wu, Daniele Guerci, Yixing Fu +2
The circularly polarized photogalvanic effect (CPGE) is studied in chiral Weyl semimetals with short-ranged quenched disorder. Without disorder, the topological properties of chira…
Imaging Self-aligned Moiré Crystals and Quasicrystals in Magic-angle Bilayer Graphene on hBN Heterostructures
Xinyuan Lai, Daniele Guerci, Guohong Li +5
Using scanning-tunneling-microscopy and theoretical modeling on heterostructures of twisted bilayer graphene and hexagonal Boron-Nitride, we show that the emergent super-moire stru…
Nature of even and odd magic angles in helical twisted trilayer graphene
Daniele Guerci, Yuncheng Mao, Christophe Mora
Helical twisted trilayer graphene exhibits zero-energy flat bands with large degeneracy in the chiral limit. The flat bands emerge at a discrete set of magic twist angles and featu…
Geometric Stiffness in Interlayer Exciton Condensates
Nishchhal Verma, Daniele Guerci, Raquel Queiroz
Recent experiments have confirmed the presence of interlayer excitons in the ground state of transition metal dichalcogenide (TMD) bilayers. The interlayer excitons are expected to…
Chiral model of twisted bilayer graphene realized in a monolayer
Valentin Crépel, Aaron Dunbrack, Daniele Guerci +2
We demonstrate that a single layer of graphene subject to a superlattice potential nearly commensurate to a supercell exactly maps to the chiral model of…
Chern mosaic and ideal flat bands in equal-twist trilayer graphene
Daniele Guerci, Yuncheng Mao, Christophe Mora
We study trilayer graphene arranged in a staircase stacking configuration with equal consecutive twist angle. On top of the moiré cristalline pattern, a supermoiré long-wavelength…
Topological superconductivity in doped magnetic moiré semiconductors
Valentin Crépel, Daniele Guerci, Jennifer Cano +2
We show that topological superconductivity may emerge upon doping of transition metal dichalcogenide heterobilayers above an integer-filling magnetic state of the topmost valence m…
Time-dependent ghost-Gutzwiller non-equilibrium dynamics
Daniele Guerci, Massimo Capone, Nicola Lanatà
We introduce the time-dependent ghost Gutzwiller approximation (td-gGA), a non-equilibrium extension of the ghost Gutzwiller approximation (gGA), a powerful variational approach wh…
