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…
Pseudomagnetic focusing of valley-polarized beams in strained graphene
Alina Mreńca-Kolasińska, Christophe De Beule, Jia-Tong Shi +4
In addition to spin, the low-energy charge carriers in graphene have two inequivalent valley flavors K and K' related by time-reversal symmetry, which can potentially serve as carr…
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…
Squeezing Quantum States in Three-Dimensional Twisted Crystals
Vo Tien Phong, Kason Kunkelmann, Christophe De Beule +4
A fundamental idea in wave mechanics is that propagation in a periodic medium can be described by Bloch waves whose conserved crystal momenta define their transformations when disp…
Chiral zigzag modes and flatbands in network models of twisted bilayer graphene
C. De Beule, F. Dominguez, P. Recher
We construct a phenomenological scattering theory for the triangular network of valley Hall states that arises in twisted bilayer graphene under interlayer bias. Crucially, our net…
Gapless interface states at the junction between two topological insulators
Christophe De Beule, Bart Partoens
We consider a junction between two topological insulators, and calculate the properties of the interface states with an effective low energy Hamiltonian for topological insulators…
